<span>Density determines what floats and what sinks. More dense sinks less dense will float.</span>
Answer:

Answer is: a. Mg + 2HCl → H₂ + MgCl₂.
Reduction hald reaction: 2H⁺ + 2e⁻→ H₂.<span>
Oxidation half reaction: Mg</span>⁰ → Mg²⁺ + 2e⁻.
In this chemical reaction, magnesium lost two electrons (oxidation, change oxidation number from 0 to +2) and hydrogen gain that two electrons (reduction, change oxidation number from +1 to 0).
When 2 moles of potassium chlorate decompose, 3 moles of oxygen are produced.
Im pretty sure its d salt water and alcohol
