The amount of W(OH)2 needed would be 448.126 g

<h3>Stoichiometric calculation</h3>

From the equation of the reaction:

W(OH)2 + 2 HCl → WCl2 + 2 H2O

The mole ratio of W(OH)2 to HCl is 1:2

Mole of 150g HCl = 150/36.461

= 4.11 moles

Equivalent mole of W(OH)2 = 4.11/2

= 2.06 moles

Mass of 2.06 moles W(OH)2 = 2.06 x 217.855

= 448.188g

How can a atom help you see both unity and diversity

Mariana [72]

Atoms show us the basic proverb about the strength and the bond when they are Unity and Diversified.

<u>Explanation:</u>

Every basic matter in the earth is composed of atoms. It is the smallest unit of the matter which is taken to observe the properties of the whole element.
The atom consists of different energy levels and consist of protons electrons and neutrons.
The atoms when are compactly arranged it result in the great strength required to bring the deformation in shape which shows that unity is always great.
But in the liquid and gas, the atoms are arranged in a randomly dispersed pattern which shows that they can be separated and involved in any process easier to get the heterogeneous product easily which is an example for Diversity.
