When the following equation is balanced, the coefficient in front of hcl is: ba(s) + hcl(aq)→bacl2(aq) + h2(g) question 4 options: 6 1 3 2

2

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced equation for the given reaction is:

Thus the coefficient for is 2.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
