Question

What is the balanced chemical equation for the reaction used to calculate ΔH∘f of SrCO3(s)?
If fractional coefficients are required, enter them as a fraction (i.e. 1/3). Indicate the physical states using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively without indicating allotropes. Use (aq) for aqueous solution.

Answer 3

Sr+(2/3)O2--->SrCO3

Answer 4

s,g,s

Answer 5

don't you need some C in there somewhere?

Answer 6

Hahaha.... uhhh yeah

Answer 7

ugh that isn't the answer either

Answer 8

Sr+2/3CO2---->SrCO3

Answer 9

but that isn't balanced...

Answer 10

...Okay give me a sec

Answer 11

2Sr+2CO3---->2SrCO3

Answer 12

s,g,s

Answer 13

but CO3 isn't something you're going to find except as an ion

I think you need solid Sr, solid C, and gaseous O2 in some combination

Answer 14

Sr+c+2/3O3---->SrCO3

Answer 15

dan what do you think?

Answer 16

nvm got it
