I. Find the molar mass for each compound. Round to the nearest percent. 1) Iron (II) oxide

2) C6H12O6

3) Carbon dioxide

4) Calcium carbonate

II. Convert from grams <---> moles and vice versa

1) 72.06 g of C to moles

2) 3.5 moles of H2O to grams

3) 63.9 g of CH4 to moles

4) 5.8 moles of CaCO3 to grams

the role of the microscope world in creating new materials .

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.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
