Answer:
A. 88
Step-by-step explanation:
A circle is 360 degrees right ? so, 136 cant be right since 136 is almost half of a circle and that angle doesn't look nearly half, 44 and 22 cant be right either since AB is 44 degrees and its growing outwards so it cant be exactly 44 and it cant be less 44 (22)
so your answer will be A. 88
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.
