for number 1: find out how many moles of HCl are in 25mL of a 0.10M solution by multiplying volume times molarity. M HCl = 25mL x 1L/1000mL x 0.10mol / 1L next calculate how many mL of xM Mg(OH)_2 solution contains the calculated number of moles of HCl. (I'm assuming you were given the...

take the charge on the cation, say Ca^+^2 and then the charge on the anion hydrogen carbonate HCO_3^- and you will criss cross the charges to form Ca(HCO_3)_2 other examples: Fe^+^3 and ClO_4^- forms Fe(ClO_4)_3 Ca^+^2 and Cl^- forms CaCl_2

I also live in Ontario and am familiar with the courses. Calculus, depending on the textbook you are using, will be broken up into a few different parts. Mainly, it'll involve studying the slope (rate of change) of tangents and secants of functions by means of differentiation and...
