1. Explain what would have to happen to the structure of this original DNA sequence in question 1, in order for a trait to change through
mutation from parent to offspring.

You will need to use the following words in your description. Gene, base pair, mutation, copy/duplicate

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 a gas formation

you need to have a picture of the atom that way we can answer it
