Answer:
covalent bond is the answer
Silicate. It is silica, SiO2 with contaminants such as Fe3+ that give it color. technically it is a tecto-silicate.<span>

The answer should be 12 since 4 x 3 = 12
This is because ammonia is NH^3 and if it has a number before it you multiply it with the rest of the chemical equation.
I hope this helps
It’s not C.The answer is B.Because as you know,Ionic bonding is the electrostatic forces of attraction between the positive and negative ions.It is a transfer of electrons between the metals(positively charged ions) and non-metals (negatively charged ions)
—->As for this case,iron is a metal and oxygen is a non-metal based on the periodic table.Hence the answer is B.
