The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction reaction _____. a)loses electrons and loses potential energy
b)gains electrons and gains potential
c)energy gains electrons and loses potential energy
d)loses electrons and gains potential energy
Answers
Answer : The correct option is a) Loses electrons and loses potential energy.
Explanation :
Reducing agent : In a redox reaction, it is oxidized by the loss of electrons and by the loses of potential energy. It is also called as electron donor.
Reducing agent reduces others by loss of electron and its oxidation state increases.
For example : Sodium is a reducing agent and itself oxidized as follows,
Therefore, the molecule that function as a reducing agent in a redox reaction is loses electrons and loses potential energy.
Final answer:
In a redox reaction, the reducing agent loses both electrons and potential energy. This process results in oxidation of the reducing agent as the oxidation state of the reducing agent increases.
Explanation:
Oxidation-Reduction Reaction
In a redox or oxidation-reduction reaction, the molecule acting as the reducing agent (or electron donor) loses electrons and loses potential energy. Hence, the correct option is a). The reducing agent donates electrons to another substance or molecule and, in this process, is itself oxidized. The oxidation state of the reducing agent increases. The reduction process involves a gain of electrons, but this gain happens to the substance that receives the electrons, not the one who donates them (the reducing agent).

Answers
Answer:
B) 88.6%
Explanation:
Percent yield equals actual yield divided by theoretical yield
actual yield is 31.0g
theoretical yield is 35g
percent yield was 88.57 which rounds up to 88.6%

According to reaction, 2 atoms of aluminum gas reacts with 3 molecules of chlorine gas.
Then 20 atoms of aluminum will react with :
of chlorine
Aluminum is a limiting reagent.
Molecules of chlorine left unreacted: 45 - 30 molecules = 15 molecules
Then 15 molecules of chlorine gas will react with :
of aluminum
10 more atoms of aluminum will required to use up all chlorine.
2:3 and an x. X is 30. 20/2 = 10 so an answer is
45/3 = 15. Both ratios are used
45 - 30 = 15 CL2 left.

c. The radioactive isotope reacts faster than stable isotopes in the nuclear reactions in the body.
d. The radioactive isotope reacts faster than stable isotopes in the chemical reactions in the body.
Answers
The statement that best explains the presence of carbon-14 in organisms is that the radioactive isotope reacts in the same way as stable isotopes in the chemicalreactions in the body. That is option B.
What is radioactive carbon-14?
Radioactive carbon-14 is a type of radioactive element that is present in the air which is assimilated in small quantities into the body during metabolism( chemical reaction of the body).
The radioactive carbon-14. can be used in a process called carbon dating because it reacts the same way as stable isotopes in their chemical reactions in the body.

1.3 x 10^22 times 3 = 3.9 x 10^22 atoms
Final answer:
The total number of atoms in 1.3 x 10^22 molecules of N(O)2 is 3.9 x 10^22 atoms since each molecule of N(O)2 consists of three atoms.
Explanation:
To answer the question of how many atoms there are in 1.3 x 10^22 molecules of N(O)2, one must be aware of the molecular composition of N(O)2. This molecule contains one nitrogen atom and two oxygen atoms, thus comprising three atoms in total. Consequently, to determine the total number of atoms, multiply the number of molecules by the number of atoms per molecule. Hence, the answer is 1.3 x 10^22 molecules * 3 atoms/molecule = 3.9 x 10^22 atoms.

The amount of hydrogen produced does not change if the volume of water was decreased to 440mL 400g.
What is Mole?
The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter.
A mole is defined as the amount of substance containing the same number of atoms, molecules, ions, etc. as the number of atoms in a sample of pure 12C weighing exactly 12 g.
The reaction will be;
Ca(s) + 2 H₂O(l) → Ca(OH)₂(aq) + H₂ (g)
Since water is in excess, because 0.1 moles of calcium requires only 0.2 moles of water which is 3.6 g, therefore changing the mass of water used will not affect the amount of hydrogen gas produced since the amount of hydrogen gas produced depends on the amount of calcium used.
Therefore, The amount of hydrogen produced does not change if the volume of water was decreased to 440mL 400g.
