What is the mass of 2.25 mol of the element Iron (Fe)? Choose the correct set up from the given choices.

a. You would divided 2.25 mol by (55.84 mol divided by 1 gram)

b. You would multiply 2.25 mol by (1mol divided by 55.84 g)

c. You would multiply 2.25 mol by (55.84g divided by 1 mol)

d. You would divide 2.25 mol by (1 mol divided by 55.84g)

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
