I believe it is either A or B
Answer:
ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
Explanation:
First, we will write the molecular equation, since it is easier to balance.
2 HBr(aq) + ZnS(s) ⇄ H₂S(aq) + ZnBr₂(aq)
In the full ionic equation we include all ions and molecular species.
2 H⁺(aq) + 2 Br⁻(aq) + ZnS(s) ⇄ 2 H⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + 2 Br⁻(aq)
In the net ionic equation we include only the ions that participate in the reaction and the molecular species.
ZnS(s) ⇄ S²⁻(aq) + Zn²⁺(aq)
Ok so simple 1Ag2O ---> 1Ag+1O2 do u understand how I got that????
Yes ...........................
Answer:
Q1=(330g)*(80cal/g)=26,400cal
Q2=(430cal)*(1cal/(g-c)*(100c=43,000cal
Q3=(430g)*(540 cal/g)= 232,200cal
Total heated absorbed is
<h3> Q1+Q2+Q3= 301,600 or 301.6 kcal</h3>
