Explanation:
The relative formula mass of a substance, shown in grams, is called one mole of that substance. So one mole of carbon monoxide has a mass of 28 g, and one mole of sodium oxide has a mass of 62 g
<span>If the volume of a sample of water is 2.5 milliliters, the volume of this sample in liters is A.) 2.5 x 10^-3 L. 1 mL = 1 x 10^-3 L. 2.5 mL = x L. Make a proportion. 1 mL : 1 x 10^-3 L = 2.5 mL : x. x = 2.5 mL * 1 x 10^-3 L : 1 mL. x = 2.5 x 10^-3 L. Therefore, 2.5 mL = 2.5 x 10^-3 L.</span>
Th first one is Iron and the second one is Xenon
In a redox chemical reaction, one species gets reduced and another gets oxidized. Manganese element is reduced in this reaction.
<h3>What is oxidized and reduced?</h3>
In a redox reaction, the increase or decrease in the oxidation number and electrons results in the reduction and oxidation of the chemical species. The oxidation and reduction occur simultaneously in a reaction.
The oxidation number of Mn in permanganate ion was +8 on the left side and decreased to +4 on the right side of the equation. Potassium permanganate is an oxidizing agent that has reduced the manganese ion of the permanganate ion.
Therefore, manganese is reduced.

La materia en estado sólido se resiste por lo general a la deformación: las torceduras, los dobleces, las hendiduras, incluso en presencia de fuerzas constantes como el peso o la gravedad. Sólo si dicha resistencia es vencida, los sólidos cambian de forma (permanente o temporalmente, dependiendo de su elasticidad).
