Answer: 32
Explanation: but you can find them on goggle
There is a 2:1 ratio between H2 and O2. so for every mol of O2 used there would be 2 mol needed, so if we use 4 mol of O2 we multiply 4 by 2 to get 8 mol of H2 used in this reaction
Answer:
MgBr2 > KBr > C3H7COOH > C6H12O6
Explanation:
A strong electrolyte is a solution that dissociate completely in solution. A weak electrolyte does not dissociate completely in solution. The more the number of particles in solution, the more the conductivity of the solution.
For the substances Lister in the question;
MgBr2(aq) ------> Mg^2+(aq) + 2Br^-(aq)
KBr(aq) -----> K^+(aq) + Cl^-(aq)
C3H7COOH(aq) ------->C3H7COO^-(aq) + H^+(aq) (poorly dissociates)
C6H12O6 does not dissociate because it is molecular
