Question

Formulas for this Timetable

CL- OH- MnO4- NO3- HCO3- SO4^2 - CO3^2- Cr2O7^2- PO4^3-
NH^4+
Na+
CU+
Pb^2+
Au^3+
B^3+
Sn^4+

I need to make the correct formulas for each one for example NH4CL NaCl and so one so the ones on the side have to match up with each one on top with the correct formulas

Answer 1

You must know how to do this so why don't you write the formulas and let me check them for you. I'm happy to do that. Just remember that any chemical formula has a zero charge so keep the number of positive charges equal to the number of negative charges. For example, Na is +1 and Cl is 1- so a 1:1 ratio is the formula for NaCl. For Ba and Cl, Ba is 2+ and Cl is 1- so you must have 2 Cl^- to make the compound BaCl2 zero charged. For Na^+ and (PO4)^3-_, Na is +1 and PO4 is -3 so you must have Na3PO4 to make that compound zero charge.
