Answer to Question #280541 in General Chemistry for ghj

Question

The reaction between solid aluminum and liquid bromine is exothermic. This reaction creates the product aluminum bromide.

What equation includes the correct formulas and demonstrates conservation of mass?

Answer 1

$2Al_{(s)}+3Br_{2(l)}\to\>2AlBr_{3(s)}$

The answer include correct formula of Aluminum, Bromine liquid and Aluminum Bromide

The mass of the products is equal to mass of reactants because there are equal numbers of atoms of each type of elements in reactants and in the products, that is, the equation is balanced.

Therefore the equation demonstrate law of conservation of mass.
