Will award brainliest! plz check my ! how does the law of conservation of mass apply to this reaction: al + 3hcl = h2 + alcl3? a. the equation needs to be balanced. there are fewer hydrogen atoms in the equation than aluminum or chlorine. b. the law of conservation of mass has already been applied. there is an equal number of each element on both sides of the equation. c. hydrogen and chlorine need to be balanced. there is an equal amount of aluminum on each side. d. only the hydrogen needs to be balanced. there are equal numbers of aluminum and chlorine.

The correct answer is...

D. Only the hydrogen needs to be balanced. There are equal numbers of aluminum and chlorine.

The correct answer would be d

Explanation:

I am sure of this because I took the test and I got 100 percent

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

have a great day because if you dont you and i will be sad
