Answer:
Ca(OH)2 + 2 HBr = CaBr2 + 2 H2O
Step-by-step explanation:
Is it H2O2 on the right side and HBr2 on the left side?
Then there is no solution.
I think the formula must look like
Ca(OH)2 + HBr = CaBr2 + H2O
You have 2 Br on the right side then it must be 2 HBr on the left side.
Ca(OH)2 + 2 HBr = CaBr2 + H2O
You have 4 Hs and 2 Os on the left side then it must be 2 H2O on the right side.
Ca(OH)2 + 2 HBr = CaBr2 + 2 H2O
Now everything looks fine.

Answer:
(dd + qq) ≥ 17
Step-by-step explanation:
We know that the number of coins that we have should be greater than or equal to 17, because it can be no less than 17. So we add dd and qq together, and we say that that sum must be greater than or equal to 17.
