Answer:
We expect 3 chlorine atoms per molecule of product produced.
Explanation:
Given the reactants 2 Sb + 3 Cl2. As you can see in periodic table, Cl always acts with an oxidation state of -1, while Sb can act with +3 or +5. If reactants are balanced in the given part of the reaction, it means that the product must be 2SbCl3. In this reaction Sb has an oxidation state of +3.
Then 2 Sb + 3Cl2 ⇒ 2 SbCl3, so there are 3 atoms of chlorine per molecule of product produced.
If Sb was acting with +5, you need 5 atoms of chlorine per product and then
2Sb + 5Cl2 ⇒ 2SbCl5, this way you need more atoms than you have.

Write the nuclear symbol and hyphen notation for each of the following isotopes:
a. mass number of 28 and atomic number of 14
b. 26 protons and 30 neutrons
Explanation:
Isotopes are types of atoms of same element with same number of protons and electrons but differ in number of neutrons in their nucleus.
Hyphen notation is written as: Elemental Symbol - (Mass number)
Nuclear Symbol : [tex]^{A}_{Z} \text{Elemental symbol}[/tex]
a. Mass number of 28 and atomic number of 14.
The element with atomic number 14 is Silicon.
The hyphen notation for this given isotope of a silicon : Si-28.
Nuclear Symbol : [tex]^{28}_{14}Si[/tex]
b. 26 protons and 30 neutrons.
Mass number of element = 26 + 30 = 56
Atomic number of element = number of proton = 26
The element with 26 atomic number is iron.
The hyphen notation for this given isotope of a iron : Fe-56.
Nuclear Symbol : [tex]^{56}_{26}Fe[/tex]
The nuclear symbol for the isotope with a mass number of 28 and atomic number 14 is 28Si, and for the isotope with 26 protons and 30 neutrons, it is 56Fe. The corresponding hyphen notations are Si-28 and Fe-56 respectively.
Explanation:To identify and write the nuclear symbols and hyphen notations for isotopes, we look at their atomic number (number of protons), mass number (protons plus neutrons), and the element's symbol. Let's apply this method to the isotopes mentioned:
For the isotope with a mass number of 28 and an atomic number of 14, the element is silicon (Si), because the atomic number 14 corresponds to silicon in the periodic table. The nuclear symbol would be 28Si and the hyphen notation would be Si-28.
For the isotope with 26 protons and 30 neutrons, the element with 26 protons is iron (Fe), thus having a mass number of 56 (26 protons + 30 neutrons). The nuclear symbol is 56Fe and the hyphen notation would be Fe-56.
The mass number is written as a superscript to the left of the element symbol, and the atomic number is written as a subscript, though it is often omitted because the element symbol implies the atomic number.

C + H2O → CO + H2 What substance are we expected to solve for?
The substance you're solving for in a chemical reaction equation, such as C + H2O → CO + H2, is the appropriate coefficients that ensure the equation is balanced, accounting for preserving same amount of each type of atom on both reactant and product sides.
Explanation:The chemical reaction in question is an example of a reaction requiring balancing. In the reaction C + H2O → CO + H2, the substance to solve for would be the coefficients that balance the chemical equation, ensuring that the number of each type of atom on the reactant side is equal to the number on the product side.
For example, if you start with balancing carbon (C) and hydrogen(H), you could get to the point where you have an odd number of oxygen atoms (O) on the product side. To correct this, a conventional balanced equation with integer-only coefficients can be derived by multiplying each coefficient by 2.
Similarly the ratio of the volumes of involved substances will be equal to the ratio of their coefficients in the balanced equation for the reaction

compare and contrast these isotopes: uranium -239, uranium -238, and uranium -235
Answer: They have same number of protons but differ in number of neutrons.
Explanation:
Isotopes are defined as the species which have same number of neutrons but differ in the number of neutrons.
Uranium is the 92nd element of the periodic table.
Atomic number is defined as the number of protons that are present in an atom.
Atomic number = Number of protons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
For the given isotopes: [tex]_{92}^{239}\textrm{U},_{92}^{238}\textrm{U}\text{ and }_{92}^{235}\textrm{U}[/tex]
For [tex]_{92}^{239}\textrm{U}[/tex]Number of protons = 92
Number of neutrons = 239 - 92 = 147
For [tex]_{92}^{238}\textrm{U}[/tex]Number of protons = 92
Number of neutrons = 238 - 92 = 146
For [tex]_{92}^{235}\textrm{U}[/tex]Number of protons = 92
Number of neutrons = 235 - 92 = 143
Hence, they have same number of protons but differ in number of neutrons.
Uranium-239, uranium-238, and uranium-235 are three isotopes of uranium. They have different numbers of neutrons and exhibit different properties. Uranium-238 is the most stable, while uranium-235 and uranium-239 are used as nuclear fuel.
Explanation:Uranium-239, uranium-238, and uranium-235 are three isotopes of uranium. Isotopes have the same number of protons but different numbers of neutrons. Uranium-239 has 92 protons and 147 neutrons, uranium-238 has 92 protons and 146 neutrons, and uranium-235 has 92 protons and 143 neutrons.
Uranium-239 and uranium-235 are both used as fuel in nuclear reactors and have the ability to undergo nuclear fission, releasing a large amount of energy. Uranium-238 is not fissile but can undergo a process called alpha decay, where it emits an alpha particle.
In terms of stability, uranium-238 is the most stable isotope among the three, followed by uranium-235 and uranium-239. Uranium-238 has a very long half-life, which makes it useful for dating rocks and determining the age of the Earth.

There is a old phrase digging a hole through the earth's center would bring you out in china if you could drill a hole from long island straight through the earth's core, where would you in fact come out
One may approach the Indian Ocean if you dug straight through any of the states.
What happen if you dig hole in china ?Although it's a common practice among American parents to tell their children they'll end up in China, that couldn't be further from the reality.
Since the Earth is a spherical, any digging that begins in one hemisphere must eventually finish in another. China is in the Northern Hemisphere and far distant.
Observe a globe more closely, China and the United States are not genuinely on opposite poles. Since they are both in the Northern Hemisphere, that is not conceivable.
You would actually emerge from the heart of the Earth if a hole were to be bored there from anyplace in the lower 48 states. midway through the Indian Ocean.
Thus, If you went straight through any of the states, you may go close to the Indian Ocean.

At what phase of the cell cycle does the genetic material double?
Answer:
The answer is the S phase.
Explanation:
The cell cycle of a eukaryote cell is composed of different phases: G1, S, G2 and M phases. Collectively, G1, S and G2 phases are called the interphase and prepares cells for division. G1 and G2 are cell growth phases. Only during the S phase, the chromosomes, that carry the genetic material of the cell, will duplicate. The M phase is the mitotic phase, in which the cell divides and produces two daughter cells.
