'with two kittens' describe the cat. So, you should write 'is sleeping'. But if you mean that all three of them are sleeping, write 'A cat and his two kittens are sleeping'.
An increase in entropy.
if H and S have the same sign the temperature will determine spontaneity
It is multiplied by 2 if the intermediate reaction is multiplied by 2
The enthalpy of reaction does not depend on the steps taken in the reaction.(Apex)
The crystalline structure of the solid most determine the entropy of a solid.
The potential energy of the reactants is greater than the potential energy of the products.
rockets need only upward thrust as a force for flight
You think probable to an endothermic chemical reaction.
Intermediate equations with known enthalpies are added together
An exothermic reaction gives out energy (the reactants heat up) as the reaction proceeds.
Payload (apex)
Not B
to simplify the design of the rocket.
