Tommy purchases a 2 liter bottle of soda and pours it into cups that hold
500 ml each. How many cups does he
use if he pours out the entire bottle of
soda?

A: 4
B:40
C: 5
D: 50

A. 4

Explanation:

We know that Tommy purchased a 2 liter bottle, in which pours 500ml of said bottle in cups, following asked of how many cups would he need before finishing the soda.

First off, 1 liter is 1,000 millileters, therefore that dividing a two liter bottle (2000ml) by 500ml will give us our answer :

2000/500

A. 4

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 !

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
