Molar mass of NaOH = 23 + 16 + 1 = 40.0 g/mol
Molar mass of HCl = 1 + 35.5 = 36.5 g/mol
NaOH + HCl = NaCl + H2O
1*40 g NaOH ------> 1*36.5 g HCl
g NaOH -------> 7.3 g HCl
36.5 g = 40 * 7.3
36.5 g = 292
mass ( NaOH ) = 292 / 36.5
mass ( NaOH ) = 8.0 g of NaOH
hope this helps!.
Answer:
endothermic
Explanation:
condensate is an endothermic change
<span>Answer for the given question is CaBr2.
Although, the given equation requires balancing of by adding one more HBr and one more H2o in resultant. The given equation will product at least one CaBr2. Hence the answer for the given equation is Calcium bromide i.e. CaBr2.</span>
