Answer:
The formula of the gas produced is .
Explanation:
Whenever metal phosphides reacts with water they form phosphine gas and alkaline solution of metal hydroxide.
So, when sodium phosphide is treated with water it gives phosphine gas and sodium hydroxide solution as a product.
The formula of the gas produced is .
The most reactive metal on the periodic table is Francium, However, Francium is an artificial element and only minimal quantities have been produced, so for all practical purposes, the most reactive metal available is Cesium, in the alkali metal family.
ANSWER In theory, Francium, in practice the Cesium
Answer:
Explanation:
The amount of matter is measured in grams. Thus, you need to convert the number of atoms of Ca (calcium) into mass to compare with 2.45 grams of Mg.
To convert the atoms of calcium into mass, you divide by Avogadro's number, to obtain the number of moles of atoms, and then divide by the atomic mass of calcium.
<u />
<u>1. Number of moles, n</u>
<u />
<u>2. Mass</u>
Then, 2.45 g of Mg represent a greaer mass than the 3.25 × 10²² atoms of Ca.
