(NH4)2CO3..... I just learned this so that why i know.
The sun i believe is one and wind
2C4H10 + 13O2 -> 8CO2 + 10H2O
2HNO3 + Ca(OH)2 ==> Ca(NO3)2 + 2H2O
<span>mols Ca(OH)2 = M x L = ? </span>
<span>Using the coefficients in the balanced equation, convert mols Ca(OH)2 to mols HNO3. </span>
<span>Then M HNO3 = mols HNO3/LHNO3. You have mols and M, solve for L.</span>
The other answer was very rude. Anyways I think the answer is Salt. Also if you view my profile don't mind the age I am actually 13. e.e
