Larger elements are able to form in a supernova explosion because the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron to be produced.
<h3>What is Supernova?</h3>
This is referred to the explosion of a star and it resulting in larger elements being formed through a process known as nucleosynthesis and is usually accompanied by an increase in the brightness of the star.
The elements produced are usually larger than elements such as iron and examples include uranium, gold etc.
This is therefore the reason why it was chosen as the most appropriate choice.

Answer:
it has a fixed volume it can also be compressed
Explanation:
a gases molecules don't move slow because they are not solid and are not compacted.
a gas does not have a fixed shape because there is nothing to hold its shape
2CH4 + 2NH3 + 3O2 ---> 2HCN + 6H2O
10g CH4 x 1molCH4/16.042gCH4 x 2mol HCN/2molCH4 = 0.6mol HCN
12g NH3 x 1molNH3/17.034gNH3 x 2molHCN/2molNH3 = 0.7mol HCN
Methane is the limiting reactant
Use the moles of Hydrogen Cyanide that you would get when used the limiting reactant, Methane
0.6molHCN x 27.028gHCN/1molHCN = 16.2grams --> 16 grams Methane
<h3>Answer:</h3>
C. 9
<h3>Explanation:</h3>
There are 2 electrons in the first shell, and 7 in the second, for a total of 9.
A flouride ion, on other hand, would have 8, since it fills that second shell with an extra electron (that's why it has a charge of -1)
