identify two mass balance equations for NaOCl
a. [Na+]
b. [OCl-]
c. [Na+] + [OCl-]
d. [OCl-] + [HOCl]
e. [Na+] + [HOCl]

Answers

Upon review of the provided chemical equations, each one is found to be balanced, with an equal number of each type of atom on both sides of the equation.

When determining if each chemical equation is balanced, we can confirm the balance by ensuring that the same number of each type of atom appears on both sides of the arrow. Here are the equations examined for balance:

a. 2Na(s) + O₂(g)
ightarrow 2Na₂O(s) - Each side has 4 Na atoms and 1 O₂ molecule, so this is balanced.b. CH4(g) + 2O₂(g)
ightarrow CO₂(g) + 2H₂O(l) - Each side has 1 C atom, 4 H atoms, and 4 O atoms, making it balanced.c. AgNO3(aq) + 2KCl(aq)
ightarrow AgCl(s) + KNO3(aq) - We have 1 Ag atom, 1 N atom, 3 O atoms, 2 K atoms, and 2 Cl atoms on both sides, so it is also balanced.

why is the solubility of a neutral organic compound unaltered by exposure to aqueous acid or base?

Answers

Neutral organic compounds are those whose pH are neither acidic nor basic. Having said so, the pH is approximately at 7. These neutral organic compounds are known not to react with the Bronsted lowry acids and Bronsted lowry bases.

Because it does not form any reaction, it can be concluded that the neutral organic compound's solubility cannot be changed or altered.

What is the STM in science

Answers

If you mean STEM, S is science, T is technology, and M is math.

Final answer:

STM in science stands for Scanning Tunneling Microscope, a device that allows visualization of atomic-level details on surfaces, revealing individual atoms and contributing to nanotechnology research.

Explanation:

In science, STM refers to a Scanning Tunneling Microscope, an instrument for imaging surfaces at the atomic level. An STM uses a sharp tip that scans a surface at a constant potential. As the tip moves close to surface atoms, electrons tunnel from the surface to the tip, creating a current that varies based on the distance between the tip and the surface. This tunneling-electron current is monitored and used to construct an image of the specimen with atomic-scale resolution. With an STM, scientists can literally see individual atoms, such as those on a sheet of gold, and structures like carbon nanotubes, providing profound insights into the physical world at the nanoscale.

A 0.5376 g sample of an unknown compound is found to contain 0.3044 g of carbonate. Could this compound be calcium carbonate?

Answers

Calcium carbonate has the formula: CaCO3
From the periodic table:
mass of calcium = 40 grams
mass of carbon = 12 grams
mass of oxygen = 16 grams
Therefore,
molar mass of CaCO3 = 40 + 12 + 3(16) = 100 grams
molar mass of carbonate = 12 + 3(16) = 60 grams

One mole of calcium carbonate contains one mole of carbonate. Therefore, 100 grams of CaCO3 contains 60 grams of CO3.
If the 0.5376 grams of the unknown substance is CaCO3, then the amount of carbonate will be:
amount of carbonate = (0.5376*60) / 100 = 0.32256 grams

Based on the above calculations, the sample is not CaCO3

What is the volume of 220 grams of an object with a density 55g/cm3

Answers

Density = mass / volume

55 = 220 / x

55x = 220

x = 4

So, the volume is 4

The volume of 220 grams of an object having density of 55 g/cm³ is 4 cm³.

What is the relation between Mass and Volume ?

Mass and volume of a body are related as follows -

M = D x V

D - density of element

M - mass of element

V - volume of element

Given is an object that has mass of 220 grams and density of 55 g/cm³.

Mass and volume are related as -

M = D x V

Rewrite the relation as follows -

V = M / D

Mass of metal object [M] = 220 g

Density [D] = 55 g/cm³

Substitute the values -

V = 220/55

V = 4 cm³

Therefore, the volume of 220 grams of an object having density of 55 g/cm³ is 4 cm³

balance this equation
Cu(NO3)2➡️CuO+NO2+O2

Answers

Balanced equation:
2 CU(NO3)2 = 2 CUO + 4 NO2 + O2
Reaction type: decomposition

Final answer:

The balanced chemical equation for the decomposition of copper(II) nitrate into copper(II) oxide, nitrogen dioxide, and oxygen is 2 Cu(NO3)2 ➔ 2 CuO + 4 NO2 + O2. This illustrates the conservation of mass by ensuring equal numbers of each type of atom on both sides of the equation.

Explanation:

The question you've asked pertains to balancing the chemical equation Cu(NO3)2 ➔ CuO + NO2 + O2. This process involves ensuring that the number of atoms for each element is the same on both sides of the equation.

To balance this equation, we start with the given substances and adjust the coefficients (the numbers in front of the chemical formulas) to make sure the atoms are balanced. After several steps of balancing, we arrive at the balanced equation:

2 Cu(NO3)2 ➔ 2 CuO + 4 NO2 + O2

This equation indicates that 2 moles of copper(II) nitrate decompose to form 2 moles of copper(II) oxide, 4 moles of nitrogen dioxide, and 1 mole of oxygen gas. The balancing process takes into account the conservation of mass, which states that atoms are neither created nor destroyed in a chemical reaction.

a glass marble has a mass of 18.5 g and a volume of 6.45 cm^3

Answers

Well since you're giving me the mass and volume, I'm going to assume that you're looking for the density.

Density = mass/volume

D = 18.5/6.45

D = 2.86822...grams/cm^3

The density of the glass marble is 2.87 [tex]g/cm^3[/tex].

Given the following data:

Mass of glass marble = 18.5 gramsVolume of glass marble = 6.45 [tex]cm^3[/tex]

In this exercise, you're required to determine the density of the glass marble.

Density can be defined as mass per unit volume of an object.

Mathematically, the density of an object is given by the formula;

[tex]Density = \frac{Mass}{Volume}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Density = \frac{18.5}{6.45}[/tex]

Density = 2.87 [tex]g/cm^3[/tex]

Therefore, the density of the glass marble is 2.87 [tex]g/cm^3[/tex].

A man and woman, drenched in sweat, limping from a building as it crumbles to the ground, muster the last of their strength to rescue humanity from its inevitable extinction at the cold, metal hands of humanoid creatures with artificial intelligence gone awry. For decades, books and movies have dictated how we think of robots. Simply the word "robot" can bring to mind images of evil, mechanical creatures bent on taking over the world and wiping out every glimmer of humanity. And yet, the truth of machines is dramatically different. Today's robots hold little in common with their villainous cousins from action-packed science fiction. Most robots have no interest in harming the human population at all; they exist to aid people in making life safer, healthier, and more productive.(PARAGRAPH #1) For example, jobs such as welding and painting are important to civilization as we know it, but experience has taught us that these activities can be hazardous to human health. In addition, fumes in automobile and airplane factories can harm organic bodies that become exposed to their toxins in the assembly process. Even when the best precautions are taken, workers may still suffer from lack of adequate ventilation. What is the answer to these difficult dilemmas? Robots. Because machines don't rely on clean air or comfortable temperatures, because they can function even in the midst of deadly gasses, they can take over with ease where humans would suffer greatly. Working together, humans and robots can get the job done.(PARAGRAPH #2) A robot's job isn't limited to the terrestrial level, either. Even in space, machines such as the R2 humanoid robot at the International Space Station complete dangerous tasks for astronauts, protecting them from potentially deadly situations. And then, when there are mundane but essential tasks to conduct on the space station, R2 takes care of those, as well, freeing up the astronauts' time for more important responsibilities. Thus, in space and on Earth, robots manage to create healthier, happier humans.(PARAGRAPH #3) In fact, there are robots on Earth that exist specifically to boost human health. Just as contact lenses enhance human sight, robotics can increase human mobility. People with disabilities and various forms of paralysis now have hope that they can achieve better range of motion, when before this wasn't possible. With the help of robots, scientists are working to create an exoskeleton that will attach itself to the outside of the human body, establishing a connection to the human brain. Neurosciencst Miguel Nicolelis has a dream. "We are working with the Brazilian government, who is helping fund the project. At the 2014 soccer World Cup celebrations we hope to have a Brazilian teenager with quadriplegia walk out and make the opening kick."(CONCLUSION) Explosions and car crashes may sell tickets for the summer blockbuster, but robots have so much more to offer, and much of it is positive service to humans. At the heart of the field of robotics is not the creation of people-destroying machines with evil artificial intelligence, but something much more useful. Robots aren't our enemies; instead, they are the valuable result of scientific endeavors to create safer lives for people everywhere.
