Answer:
Molecular Mass:
1. 40g per mole
2. 19g per mole
3. 64g per mole
4. 32 g per mole
5. 17g per mole
6. 59.5g per mole
7.58.5 g per mole
8.220g per mole
9. 78g per mole
10. 200g per mole
Explanation:
Molecular Mass = Number of atom x atomic mass of an element

Answer:
It is always less than the theoretical yield
Explanation:
For many chemical reactions, the actual yield is usually less than the theoretical yield. This is due to possible loss in the process or inefficiency of the chemical reaction.
C. Neon is the element which is not likely to form bonds. This is because neon is a noble gas, which means that it already has the maximum of 8 valence electrons, and doesn't need more, whereas gold, oxygen, and mercury can bond more electrons.
Answer:
13
Explanation:
because the number of protons and electrons in the atom are the same
Out of the following given choices;
A) when there are too many neutrons
B) when the neutrons are slowed down
C) when there is a chain reaction
D) when there is critical mass
The answer is A. A fission nuclear reactor is controlled by regulating the number of neurotoxins produced in the chain reaction. Too many neutrons cause an accelerated chain reaction that causes enormous heat to be generated in a short amount of time which could cause an explosion. Control rods , made of “neutron poisons”, e.g. cadmium, are put in the reactors to control the number of neutrons at any one time
