At a pressure 41 kpa, the gas in a cylinder has a volume of 18 liters. assuming temperature remains the same, if the volume of the gas is decreased to 10 liters, what is the new pressure

i dont know

explanation:

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
