B. carbon because it's atomic number is 6
The answer is (c) lessen the environmental impact of acid rain. This is because acid rain is mainly due to the <span>sulfur dioxide (and nitrogen oxides) emissions from smokestacks (and motor vehicles). Controlling the sulfur dioxide emissions would mean an attempt to lessen the environmental impact of acid rain.</span>
Molar mass
NH3 = 17 g/mol
N2 = 28 g/mol
4 NH3 + 6 NO = 5 N2 + 6 H2O
4 x 17 g NH3 ------------ 5 x 28 g N2
?? g NH3 --------------- 300 g N2
300 x 4 x 17 / 5 x 28 =
20400 / 140 => 145.71 g of NH3
I believe the correct answer from the choices listed above is the second option. The factor that <span> influences both solubility and the rate of dissolution would be temperature. It is the only factor from the list that affects both. Solubility is a function of temperature only while the rate of dissolution is a function of all. Hope this answers the question.</span>
