Structure is achieved when a protein folds into a compact, three-dimensional between side-chain r groups of amino acids. structure is the sequence of amino acids in a protein. structure describes the alpha helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain. structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex. a. primary,
b. secondary,
c. tertiary,
d. quaternary

The answer to your question is:

Explanation:

1._Terciary__ structure is achieved when a protein folds into a compact, three-dimensional between side-chain R groups of amino acids.

2._Primary___ structure is the sequence of amino acids in a protein.

3._Secondary___ structure describes the alpha helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain.

4._Quaternary___ structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.
