construct a model of a plant or animal cell it must be made of edible materials you may use a sandwich bread for the cell you may also choose any food products example candies chocolate nuts etc for the other cell organelles and label them avoid using materials that have an unpleasant odor that maybe considered offensive. Base also in your task in the provided rubric, after constructing a model answer the following questions below if possible let them attached a picture of their cell model or make a drawing of it

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 !
