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!.
For machines such as a rake the output force is less than the input force. If the input force of the rake is 10 newtons and the output force is 5 Newtons mechanical advantage is .5
The answer to your question would be sound because dogs have excellent hearing so when it hears loud thunder it was a frightened reaction
