Is sio2 most likely a molecular, metallic, ionic, or covalent-network solid? silicon readily reacts to form silicon dioxide, , which is quite hard and is insoluble in water. is most likely a molecular, metallic, ionic, or covalent-network solid? sio2 is a molecular solid. sio2 is a metallic solid. sio2 is an ionic solid. sio2 is a covalent-network solid?

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 !
