Identify the statements that are consistent with the law of conservation of mass. a. New elements are produced using chemical reactions.
b. All samples of a given chemical compound consist of the same elements in the same proportion.
c. In a chemical reaction, the atoms of the reactants rearrange to form new compounds.
d. Chemical reactions neither create nor destroy mass in an isolated system.
e. The mass of the products in a chemical reaction are typically greater than the mass of the reactants.

answer; economic order quantity;

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
