Light: not physical

The reactants are Mg (s) +HCl (aq)

Answer:

MgCl₂ and H₂

Explanation:

The reaction between Magnesium and Hydrochloric acid is a single replacement reaction. In a single replacement, a metallic ion replaces another ion based on their positions in the activity series.

The reaction can be written as:

              Mg + HCl → ?

The ionic form can be written as:

             Mg + H⁺ + Cl⁻ → ?

Now lets look at the reaction halves:

            Mg → Mg²⁺ + 2e⁻        This is an oxidation half in which 2e⁻ is lost

           2H⁺ + 2e⁻ → H₂         This is a reduction half in which 2e⁻ is gained

In the activity series, Mg is higher up and is able to replace the hydrogen ions that in the lower part of the series.

Combining both reaction halves, we have:

               Mg + 2H⁺ → Mg²⁺ + H₂

If we include the spectator ions we have:

             Mg + 2HCl → MgCl₂ + H₂

Answer:

On the other hand, the molecules in liquid water are held together by relatively strong hydrogen bonds, and its enthalpy of vaporization, 40.65 kJ/mol, is more than five times the energy required to heat the same quantity of water from 0 °C to 100 °C

Answer: The energy required to vaporize the given amount of water is 22600 J

Explanation:

The conversion involved in this process are:

[tex]H_2O(l)(100^oC)\rightarrow H_2O(l)(100^oC)[/tex]

To calculate the amount of heat required at constant temperature, we use the equation:

[tex]q=m\times L_{vap}[/tex]

where,

[tex]q[/tex] = amount of heat absorbed = ?

m = mass of water = 10 g

[tex]L_{vap}[/tex] = latent heat of vaporization = 2260 J/g

Putting all the values in above equation, we get:

[tex]q=10g\times 2260J/g=22600J[/tex]

Hence, the energy required to vaporize the given amount of water is 22600 J

Answer:

38.36 L.

Explanation:

where, P is the pressure of H₂ in atm (P = 1.0 atm, STP conditions).

V is the volume of H₂ in L (V = ??? L).

n is the no. of moles of H₂ in mol (n = mass/molar mass = (10.0 g)/(2.0 g/mol) = 5.0 mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of H₂ in K (T = 0.0°C + 273 = 273.0 K, STP conditions).

∴ V = nRT/P = (5.0 mol)(0.0821 L.atm/mol.K)(273.0 K)/(1.0 atm) = 38.36 L.

Answer:

The hot tea should transfer 25.63 kJ the surroundings to cool the tea.

Explanation:

Q = m.c.ΔT,

where, Q is the amount of heat has to be transferred from the tea to the surroundings to cool the tea (Q = ??? J).

m is the mass of the hot tea (m = dV = (1.0 g/mL)(250 mL) = 250 g), suppose the density of water is the density of tea.

c is the specific heat of the hot tea (c = 4.10 J/°C.g).

ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = 350 K - 375 K = -25°C).

∴ Q = m.c.ΔT = (250 g)(4.10 J/°C.g)(-25°C)) = - 25630 J = - 25.63 kJ.

So, the hot tea should transfer 25.63 kJ the surroundings to cool the tea.

Microwave is Electromagnetic, as is radio wave, ocean is mechanical, s is seismic. A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one. Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

Explanation:

Waves are either mechanical or electromagnetic. Mechanical waves require a medium to propagate and can be longitudinal or transverse, like sound waves and waves from a tuning fork. Electromagnetic waves, such as light, do not need a medium and can travel through a vacuum.

To classify waves as either mechanical or electromagnetic, it is essential to understand their fundamental characteristics and how they propagate. Mechanical waves, like the ripples created in water from a stone's impact or the waves coming from a tuning fork, need a medium (like air, water, or solids) to travel through. These waves can be longitudinal, where the disturbance occurs in the same direction as the wave's propagation, or transverse, where the disturbance is perpendicular to the direction of wave propagation.

On the other hand, electromagnetic waves comprise oscillating electric and magnetic fields and can propagate through a vacuum. The classic example of an electromagnetic wave is light, which can travel through empty space and does not require a medium.

Examples of mechanical waves include sound waves and seismic waves, while examples of electromagnetic waves include light waves, radio waves, and X-rays. Maxwell's equations offer further insight into the behavior of electromagnetic waves, predicting their properties and the speed at which they travel.

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute.

Explanation:

Definition:

Solvent is the that part of solution which is present in large proportion and have ability to dissolve the solute. In simplest form it is something in which other substance get dissolve. The most widely used solvent is water, other examples are toluene, acetone, ethanol, chloroform etc.

Water is called universal solvent because of high polarity all polar substance are dissolve in it. Hydrogen is less electronegative while oxygen is more electronegative and because of difference in electronegativity hydrogen carry the partial positive charge while oxygen carry partial negative charge.

Water create electrostatic interaction with other polar molecules. The negative end of water attract the positive end of polar molecules and positive end of water attract negative end of polar substance and in this way polar substance get dissolve in it.

Example:

when we stir the sodium chloride into water the cation Na⁺ ions are surrounded by the negative end of water i.e oxygen and anion Cl⁻ is surrounded by the positive end of water i.e hydrogen and in this way all salt is get dissolved.

Cell potential is defined as D. difference between reduction potentials of half cells.

The cell potential is calculated by taking the difference in the half reaction which is reductive and the half reaction which is oxidative.

Symbolically: E°cell = E°cathode − E°anode

Under standard temperature and pressure condition, the standard cell potential of hydrogen electrode is 0 V. The cell potential is obtained by subtracting because it is impossible to measure the exact single electrode potential hence it is measured in the form of difference.

Considering the definition of pH, the pH of an acid solution containing 0.10 M HNO₃ is 1.  

You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:

pH= - log [H⁺]

On the other side, a strong acid is an acid that completely dissociates into hydrogen ions and anions in solution at constant temperature and pressure. Under these conditions, the concentration of a strong acid equals the concentration of hydrogen ions.

In this case, HNO₃ is a strong acid, so:

[HNO₃]= [H⁺]= 0.10 M

So the pH can be calculated as:

pH= - log (0.10 M)

Solving:

pH= 1

Finally, the pH of an acid solution containing 0.10 M HNO₃ is 1.

Learn more:

The pH of a solution can be calculated using the formula pH = -log [H3O+]. In this case, the pH of a 0.10 M HNO3 acid solution would be 1.0 because HNO3 completely dissociates in water, and the hydronium ion concentration is 0.10 M.

This problem pertains to the field of acids and bases, specifically dealing with the concept of pH. The pH of a solution can be calculated using the formula pH = -log [H3O+], where [H3O+] stands for the hydronium ion concentration. Bear in mind that for a strong monoprotic acid such as HNO3, the concentration of this acid equals the concentration of hydronium ions due to its complete dissociation in water.

In this case, [H3O+] equals 0.10 M, the same as the concentration of HNO3. Now, substituting this into the pH formula gives us pH = -log(0.10), which simplifies to a pH of 1. This means the pH of a 0.1M HNO3 solution would be 1.0.

The entropy of a system decreases when a gas condenses into a liquid, which corresponds to option B. a gas condensing. This reflects the second law of thermodynamics where the total entropy of the universe still increases while local decreases are possible with energy transfer.

Entropy is a measure of disorder or randomness in a system, and it is an important concept in thermodynamics. In the question presented, the process in which entropy decreases is the condensation of gas into a liquid or solid. Therefore, the correct answer to which system sees a decrease in entropy is B. a gas condensing.

For example, when water vapor condenses on a cold surface, it goes from a disorderly gas phase to a more ordered liquid phase, which means that its entropy decreases. Energy transfer is necessary for the entropy of a system to decrease. This is consistent with the Second Law of Thermodynamics, which states that for the entropy of a system to decrease, the entropy of the surroundings must increase by a greater amount, thus the total entropy of the universe still increases.

STP has been the state of standard temperature and pressure. At STP, the temperature has been 273.15 K, while the pressure has been 1 atm.

Assuming ethane has been an ideal gas:

PV = nRT

P = pressure = 1 atm

V = volume

n = moles = 6.1

R = constant = 0.08206 atm.L/mol.K

T = temperature = 273.15 K

Substituting the values:

Volume = 6.1 mol × 0.08206 atm.L/mol.K × 273.15 K

Volume = 136,6 L.

The volume of ethane at STP has been 136,6 L.

Considering the temperature of the gas being 100[tex]\rm ^\circ C[/tex]:

Elements in the same group of the periodic table, such as lithium and sodium, usually have similar properties. These properties stem from the same number of electrons in their outermost shell.

In the periodic table, elements that are in the same group (vertical column) often have similar properties. This is because they have the same number of electrons in their outermost shell, which determines their chemical behavior. For instance, lithium (Li) and sodium (Na) are both in Group 1, and they share similar characteristics: they are highly reactive metals that react with water to produce hydrogen gas. These elements have a single electron in their outermost shell, which makes them eager to donate that electron in reactions, leading to similar chemical properties.

A individual who practices accounting or accountancy is called an accountant. Accountants may be using titles like "Chartered Accountant," "Chartered Certified Accountant," "Chartered Accountant," or "Registered Public Accountant" after passing certification tests provided by respective professional associations. These experts may be made responsible for professional wrongdoing and are given specific duties by legislation, such as the authority to verify a company's monetary accounts. Non-qualified accountants have no statutory privileges or obligations and are free to operate independently or in the employ of a competent accountant.

Certified Public Accountants (CPAs) and Public Accountants are the two designations for licensed accountants in the United States (PAs). Certified Management Accountants (CMAs) and Certified Internal Auditors (CIAs) are examples of unlicensed accountants (CMAs). Although individuals may get many certificates, the main distinctions between them are their legal standing and the kinds of services they offer. In addition, a lot of accounting work is done by uncertified people who can be working under a certified accountant's supervision. As was already said, the majority of accountants are employed by private companies or are free to provide their services without being certified.

Answer:

1. [OH⁻] = 2.4 x 10⁻¹⁴ M.

2. [H₃O⁺] = 4.167 x 10⁻¹ M.

Explanation:

Firstly, we need to calculate the molarity of Mg(OH)₂:

M = (no. of moles of solute)/(V of the solution (L).

∴ M of MgCl₂ = (no. of moles of solute)/(V of the solution (L) = (1.2 x 10⁻¹⁴ mol)/(1.0 L) = 1.2 x 10⁻¹⁴ M.

1. [OH⁻]:

Mg(OH)₂ → Mg²⁺ + 2OH⁻.

∴ [OH⁻] = 2(1.2 x 10⁻¹⁴) = 2.4 x 10⁻¹⁴ M.

2. [H₃O⁺]:

∵ [H₃O⁺][OH⁻] = 10⁻¹⁴.

∴ [H₃O⁺] = 10⁻¹⁴/[OH⁻] = 10⁻¹⁴/(2.4 x 10⁻¹⁴ M) = 4.167 x 10⁻¹ M.
