So, law of conservation of mass.
The mass of the reactants have to equal the mass of the products.

Answer 6

Yeah, what Arithmetic said. XD

Answer 7

Oh okay, thank you!! Science is so confusing to me aha

Answer 8

Could you help with a few others?

Answer 9

Ok thank you :)

Hydrogen gas (Hsmall2) and chlorine gas (CIsmall2) react to form hydrochloric acid (HCI). What is the correct balanced chemical equation for this reaction?

a. 2Hsmall2+ 2Csmall2=HCI
b. Hsmall2+ CIsmall2= 2HCI

two more options one sec

Answer 10

H2 + Cl2 -> 2HCl

Answer 11

c. 2Hsmall2+CIsmall2= 2HCI
d. Hsmall2+CIsmall2=HCI

Answer 12

are any of the 2's small, at the bottom?

Answer 13

Correct

Answer 14

Ok so B?
