Maria gets a kit that lets you grow a mineral. The instructions say to pour a packet of liquid into a small container and to place the container in a sunny area. Maria follows the directions and when the liquid evaporates, she observes tiny minerals that are left behind in the container. What is the process called?

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 !

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
