A sample of krypton gas occupies 66.7 L at 25C assuming constant pressure what will the temperature of the gas be in kelvin if the volume increases to 100 L

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

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.

the answer is c i took the test

answer carbon and three oxygen atoms;
