To compute for the empirical formula, assume there is 100 grams of the compound. That means there is 40.28 g B, 52.2 g N and 7.53 g H. Convert the mass into moles using their molar masses:
40.28 g B * 1 mol/10.811 g = 3.725835 mol B
52.2 g N * 1 mol/14 g = 3.72857 mol N
7.53 g H * 1 mol/1 g = 7.53 mol H
Divide all the moles by the smallest amount which is 3.725835 mol.
B: 3.725835/3.725835 = 1
N: 3.72857/3.725835 = 1
H: 7.53/3.725835 = 2
Therefore, the empirical formula is BNH₂.
Chemical- it produces ammonia.
Answer:
Liquid
Explanation:
Earth’s core is liquid because it’s hot enough to melt iron, but only in places where the pressure is low enough
Answer:
During World War II, rationing was implemented to control the equal distribution of items in short supply. Although the primary goal of rationing was equal distribution, a secondary goal was to free valuable factory resources for war production.
