1) The names of the molecules
2) Write the chemical equation

3) Balance the chemical equation
1 fluoride in the reactants and 1 fluoride in the products
1 carbon in the reactants and 1 carbon in the products
4 hydrogens in the reactants and four hydrogens in the products
1 oxygen in the reactants and 1 oxygen in the products
Since the number of atoms in the reactants is the same that the number of atoms in the products, the chemical equation is balanced.

It's A, metals. Metals are solid at room temperature but still very malleable and the best conductors. Metalloids can still conduct electricity but nowhere near as well as metals.
The primary structure is the amino acids' unique sequence. The polypeptide's local folding to form structures such as the α-helix and β-pleated sheet constitutes the secondary structure. The overall three-dimensional structure is the tertiary structure
