Answer:
1. CaCO3(s) <=> CaO(s) +CO2 (g) Delta H = +178 kJ/mol
Since Delta H is positive, it means the reaction is endothermic
a. An increase in temperature will will shift the equilibrium position to the right, thus forming more products
b. A decrease in the temperature will shift the equilibrium position to the left, thus forming more reactants
2. PCl3(g) + Cl2(g) <-> PCl5 (g) Delta H= -88 kJ/mol
From the above, Delta H is negative which implies exothermic reaction.
c. Increasing the temperature will shift the equilibrium position to the left, thus forming more reactants.
d. Decreasing the temperature will shift the equilibrium position to the right, thus forming more products
Answer: Exploratorium Senior Scientist Paul Doherty explains why not—the orbit of the moon is tilted relative to the orbit of the Earth around the sun, so the moon often passes below or above Earth. At those times, it does not cross the line between the sun and the Earth, and therefore does not create a solar eclipse.

Answer:
LDPE would be the best choice for a hand warmer designed to release heat quickly.
Explanation:
Judging from the graph, the LDPE plastic releases heat quicker than the Latex. (and I also did the gizmo-)
