Please balance the equation, putting the correct coefficient in each box.

Mariulka [41]

Answer: $Bi(OH)_3+3HNO_3\rightarrow 3H_2O+Bi(NO_3)_3$

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 will be:

$Bi(OH)_3+3HNO_3\rightarrow 3H_2O+Bi(NO_3)_3$

A lahar is a type of mudflow that occurs?

Natalka [10]

A lahar is a type of mudflow that occurs after a volcanic eruption. It is a sort of mudflow or trash stream made out of a slurry of pyroclastic material, rough flotsam and jetsam, and water. The material streams down from a fountain of liquid magma, normally along a waterway valley. Lahar is the most deadly by-products of the eruption because of the speed they can travel.
