Since the reaction gives off heat energy it is considered to be an exothermic reaction
In order to balance an equation, we apply the principle of conservation of mass, which states that mass can neither be created nor destroyed. Therefore, the mass of an element before and after a reaction remains constant. Here, the balanced equation becomes:
4Al + 3O₂ → 2Al₂O₃
The coefficients are 4, 3 and 2.
Answer:What is the question
Explanation:
Hard question !! Is this math .. if not then oh okay cause I’m bad at math but good at everything else so let me think about it !
