Answer: The ratio of carbon to bromine atoms in the molecule is 3:1
Explanation:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions.
Chemical formula shows the elements in a compound and the relative proportions of those elements.
The chemical formula given for the compound is 
which means the ratio of carbon to bromine atoms is 3: 1.
Thus the ratio of carbon to bromine atoms in the molecule is 3:1
Answer:
Cl is more likely to than Na
Explanation:
The question asks for the element more take up an electron from the other
The ability of an atom to take take or give electrons in a chemical reaction, depends on its electron affinity and ionization energy, respectively
Chlorine, Cl, has the highest electron affinity in the periodic table which makes it attract electrons more towards itself
Sodium, Na, has a low ionization energy (about 2/5 of that of chlorine) than chlorine, Cl, making sodium more readily able to give its valence electron in a reaction
Therefore, Cl is more likely to take up an outer electron from Na.
