Explanation

The total work done in moving a body along a closed path in a gravitational field is always zero.

This is because the gravitational field is conservative,

Meaning the work done by the conservative force is independent of the path taken and

Only depends on the initial and final positions,

And for a closed path, the initial and final positions are the same.

Explanation

The molar mass of HCl is 36.5 g/mol. To find the moles of HCl:

Moles of HCl= 36.5g/mol16.5g =0.452 moles

Since the reaction is 1:1, 0.452 moles of HCl will produce 0.452 moles of NaCl.
