Answer:
6) 225.8 g
7) 1.01 g
8) 21.624 g
Explanation:
6) Molar Mass of Lithium Bromine: 86.845
86.845 * 2.6 = 225.8 g
7) Molar Mass of Neon: 20.180
20.180 * 0.05 = 1.01 g
8) Molar Mass of Water Vapor: 18.02
18.02 * 1.2 = 21.624 g
Answer: Law of conservation of mass explains these observations.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
Mass of reactants= mass of Mg+ mass of 
= 48 g + 32 g = 80 g
Mass of products = mass of 
= 80 g
Thus mass of reactants is equal to mass of products, thus law of conservation of mass is obeyed.

Hello!
There are two tests one could use to identify a solution of Ag₃PO₄ (keep in mind that this compound is very insoluble and very little amounts of it are in solution)
For Ag⁺ ion: Precipitate with NaCl. The adding of NaCl should produce a white precipitate.
Ag⁺(aq) + NaCl(s) → AgCl(s)↓ + Na⁺
For PO₄⁻³ ion: Precipitate with Ammonium Molybdate and Acid. This reaction should produce a yellow precipitate:
PO₄⁻³<span> + 3NH</span>₄⁺<span> + 12MoO</span>₄⁻²<span> + 24H</span>⁺<span> </span>→<span> (NH</span>₄)₃PO₄.12MoO₃(s)↓<span> + 12H</span>₂<span>O
