Atoms
Explanation:
This is also a form of molucules
<span>choices are:
Zirconium metal plus hydrogen chloride yields zirconium chloride solution and hydrogen gas
Xenon solid plus hydrochloric acid yields xenon chloride and hydrogen gas
Zinc metal plus hydrogen chloride yields zinc dichloride plus hydrogen gas
Zinc metal plus an aqueous solution of hydrochloric acid yields an aqueous solution of zinc chloride plus hydrogen gas
right ans is:

Weathering is the process of breaking large rocks and boulders into much smaller ones. Weathering can be brought about by wind and water mostly. Sometimes even biological forces account for some types of weathering.
When the concentration is expressed in mass percentage, that means there is 3 g of solvent H₂O₂ in 100 grams of the solution. Then, that means the remaining amount of solute is 97 g. We use the value of molarity (moles/liters) to determine the amount of solution in liters, denoted as V. The solution is as follows:
0.02 mol KMnO4/L solution * 158.034 g KMnO4/mol * V = 97 g KMnO4
Solving for V,
V = 30.69 L
