Zinc metal reacts with hydrochloric acid, HCl (aq), react to give hydrogen gas, H2 (g) and aqueous zinc chloride, ZnCl^2 (aq). A 0.4000 g sample of impure zinc fully reacts completely when added to 750.0 L of 0.0179 M HCl. After the reaction, the molarity of the solution has been reduced to 0.00403 M. What is the percent by mass of zinc in the sample?

the answer is a. co2, this would be colder than the : )

explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

the answer is minerals.
