261.162 grams. Use the equation n=M÷Mr.
Answer: No
Explanation: The reason for this is because calcite has a hardness of 9 while feldspar has a hardness of 21. Calcite can scratch Gypsum which has a hardness of 3.

Explanation:
"A formal charge (FC) is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity" (chemlibretext).
We can obtain the formal charge from the formula;
Formal Charge = [number of valence electrons on atom] – [non-bonded electrons + 1/2number of bonds].
A structure in which SO2 has a zero formal charge is attached to this answer.

Answer:
Hydrogen is a very reactive element. It doesn't exist as a single atom in nature. Neither do any of the other binary nonmetals -- nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. They're too prone to react with something. They react with each other and form binary molecules because the binary molecules are more stable than single atoms (by a lot!). Compounds with other atoms are even more stable, so hydrogen reacts with oxygen to form water, and chlorine reacts with sodium to form table salt.
