When we see a compound that has parentheses, we treat them the same way we would in algebra. If we saw 2(x-4), we could distribute that 2 so that it would be 2x-8, right? Parentheses work in much the same way, but we usually use subscripts to be distributed. Fe2(SO4)3 looks complicated. But remember our subscripts are just part of the chemical formula and they are still to the right of whatever elements we're looking at. This formula tells us there are 2 irons, 3 sulfurs, and 12 oxygens (just like when we distributed the 2 in the algebraic formula and multiplied above, we multiply the subscripts). Let's look at an example: which of the following compounds has 9 hydrogens (H)? Options: (NH4)2HPO4 C4H8BeF3NO4 C6H12O6 CH6NO3P
