Balance each of the following chemical equations. A) Mg(s)+Br2(l)→MgBr2(s)
Express your answer as a chemical equation. Identify all of the phases in your answer.
B) P4(s)+O2(g)→P4O10(s)
Express your answer as a chemical equation. Identify all of the phases in your answer.
C) Ba(OH)2(aq)+HNO3(aq)→Ba(NO3)2(aq)+H 2O(l)
Express your answer as a chemical equation. Identify all of the phases in your answer.
D) Cr2O3(s)+C(s)→Cr(s)+CO(g)
Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation:

The question states that the chemical equations should be balanced and the phases should also be indicated. The abbreviations of the phases have been indicated in the question with

i) (s) meaning the compound is in solid

ii) (aq) meaning the compound is in aqueous form

iii) (l) meaning the compound is in liquid

iv) (g) meaning the compound is in gaseous form

Balanced chemical equation is that in which the number of individual atoms on the reactant side is equivalent to the number of the same individual atoms on the product side.

Only the answer (the balanced chemical equations) will be written below.

A) This reaction is balanced

Mg(s) + Br₂(l) ⇒ MgBr₂(s)

B) P₄(s) + 5O₂(g) ⇒ P₄O₁₀ (s)

C) Ba(OH)₂(aq) + 2HNO₃(aq) ⇒ Ba(NO₃)₂(aq) + 2H₂O

D) Cr₂O₃(s) + 3C(s) ⇒ 2Cr(s) + 3CO(g)

ill try to . no promises tho.

explanation:

thats a little if u want the answer just look it up on google thats what i do haha : )
