Answer:
The heat of vaporization of water is 2257-J/g - each grams must release 2257-J of thermal energy. When water condenses its temperature remains constant.
Q = m x Hv ===> 50-g x 2257-J/g = 112,850-J = 112.9-kJ
<span>a. 5.
b. 3.

The <span>simple machine found on the head of the ax is </span>Wedge. A wedge is an inclined plane that can be moved. When an ax is used
to split wood, the ax handle
exerts a force on the blade of
the axe, which is the wedge. That force pushes the wedge
down into the wood. The wedge in turn exerts an
output force splitting the wood in two.
KOH is the limiting reagent
The molar ratio is 1:2
So if you have 6 moles of MgCl2 you need 12 moles of KOH
