Answer:
C. matter
Explanation:
When hydrogen atoms collide at very high speeds, the natural electrostatic repulsion that exists between the positive charges of their nuclei is overcome and the atoms fuse, this fusion of light hydrogen atoms produces a heavier element, helium.
<em>In short, nuclear fusion is a process by which nuclear reactions between light elements form heavier elements (up to iron), therefore fusion produces new types of matter. </em>

First, determine the molar mass of the empirical formula given for the substance. This can be solved by adding the products of the number of moles and the molar mass of each of the atom as shown below,
M = (3 mols C)(12 g C/1 mol C) + (2 mols H)(1 g H/1 mol H) + (1 mol N)(14 g N/1 mol N)
M = 52 g/mol
Then, divide the given molar mass above by the calculated value.
n = 208.19 g/mol / 52 g/mol = 4
Then, multiply the value of n to the coefficients of the atoms giving us the answer.
<em> ANSWER: C₁₂H₈N₄</em>
I believe the correct answer is A
Is it because the bonds between hydrogen molecules for easier than bonds between chlorine molecules?
Answer: a. BaO
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here element barium is having an oxidation state of +2 called as 
cation and 
is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
