Answer 3

Alright! To make this easier, do you know what the Law of Conservation of Mass is?

Answer 4

UHH NO SRRY

Answer 5

That's ok! I will introduce it to you:
Mass is NEITHER created nor DESTROYED in chemical reactions. What does this mean about the mass of the ''Products'' and ''Reactants'' sides? :D

Answer 6

i still dont get it

Answer 7

Ok. Let's say we are combining oxygen and hydrogen to get water. The mass on the ''Reactants'' side is 25 grams. During and after the reaction, no mass is LOST or ADDED. Meaning, 25 grams STAYS 25 grams.

In a chemical reaction, the mass of the products in a chemical reaction must equal the mass of the reactants.

Answer 8

Do you think you understand it now? :D

Answer 9

so a

Answer 10

Correct! From now on, remember that:
Mass on one side of the reaction WILL ALWAYS EQUAL the mass on the other side of the reaction. Remembering this will help you later. :D
Since there are 50 grams in one side, the other side MUST have 50 grams.

Answer 11

I am sorry if I confused you on something. I was wanting you to understand why both sides always the same mass. :)

Answer 12

WAIT, it is not A. Sorry!

Answer 13

oh ok

Answer 14

wht grade are you in

Answer 15

A states that the mass will be LESS than 50 grams. As I explained earlier, the mass on both sides will be EXACTLY the same. This means that B is the answer. :D

Answer 16

oh ok that was actuaally my second answer

Answer 17

I am in 10th grade. ^^
If you have ANY confusion with this problem, please let me know. Just remember that the mass on both sides will ALWAYS be the same no matter what. If you can remember just this, you will be fine.

Answer 18

thx im in 8th

Answer 19

No problem. I like helping others; I hope you are learning things from me. That way, whenever these topics show up in high school, you will be ready. :D
