Ammonium perchlorate appears as a white, crystalline solid or powder. Classified as a division 1.1 explosive if powdered into particles smaller than 15 microns in diameter or if powdered into larger particles but thoroughly dried. Does not readily burn, but will burn if contaminated by combustible material. May explode under prolonged exposure to heat or fire. Used to make rocket propellants, explosives, pyrotechnics, as an etching and engraving agent, and in analytical chemistry.
Carbon and iron alloys are called steel.
Answer:
Coal is the fossil fuel causing the most pollution.

If enough HCl is not added, the percent yield will be lower as all the magnesium metal has not reacted with HCl.
<h3>What is percent yield of a reaction?</h3>
The percent yield of a reaction is the ratio of the actual yield and the expected yield expressed as a percentage.
- Percent yield = actual yield/expected yield × 100%
The reaction between magnesium metal and HCl liberates hydrogen gas and forms magnesium chloride salt.
If enough HCl was not added to react with all the magnesium metal, the actual yield will be lower.
Hence, percent yield will be lower as well.
Therefore, the percent yield will be lower if all the magnesium metal has not reacted with HCl.
