Choose the best definition of the difference between a structural formula and a Lewis structure of a molecule. *Structural formulas show all the valence electrons orLewis structures show both lone pairs of electrons as well as the bonds orStructural formulas show both lone pairs of electrons as well as the bonds orStructural formulas don't exist while Lewis structures dopls answer quick I will give branylist

structure formula shows only number of atoms and how many each bonded, like fewer details..

Explanation:

But lewis structure gives you the original geometry of the structure that naturally in the environment

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

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 !
