write and balance the chemical equation. please give the answer as soon as possible before 28-4-14.
How do I find the molecular weight and the molar expression of Ca(OH)2 + H3PO4 = Ca3(PO4)2 + H2O After balancing it? I've been confused about this equation.
Since polyatomic ions naturally have subscripts with them, then do we ignore them when trying to balance a chemical equation?
I already know how they balnace I just don't understand how they balance. why does the O(2*) balance to 25? 2 C(8*)H(18*) + 25 0(2) yields 16 CO(2*) + 18 H(2*)O These ones have me...
i need help♥
