Answer:

A. glycine (NH 2 CH 2 COOH).

Explanation:

Hello,

In this case, we understand amino acids as organic compounds that assemble to form high order molecules called proteins, therefore, they are the building blocks of life. Structurally, as shown on the first attached picture, they make up of both an amino group and a carboxily group having the organic chain below. In such a way, the only listed compound that matches with such the aforesaid definitions is glycine whose structure is shown on the other attached document.

Best regards.

How many grams of calcium hydride are needed to form 4.550 g of hydrogen gas
stealth61 [152]
Molar mass 

CaH₂ = 42.0 g/mol

H₂ = 2.0 g/mol

<span>Balanced chemical equation :

</span>CaH2 + 2 H₂O = Ca(OH)₂ + 2 H₂

42.0 g CaH₂ ---------------------  4.0 g H2
    ? g CaH₂ ---------------------- 4.550 g H2

mass = 4.550 * 42.0 / 4

mass = 191,1 / 4

mass =<span> 47.775 g of CaH₂</span>
