My teacher had our class do a lab in which we reacted magnesium metal with hydrochloric acid to form magnesium chloride and hyrdogen gas. I found out how many grams I should have recovered .822 grams of magnesium chloride, but instead I recovered .990 grams. My teacher wants us to include 2 errors d...

this is what it says when translated: The Germisch from 5-Nitro and 3-Nitro-2-aminopyridin, received after by nitrating from 2-Aminopyridin and relocation of the 2-Nitraminopyridin primarily developed, in that for instance 50fachen quantity of H2O was suspended and with konz. HCl up to the complete ...

those symbols are placed like a coeefficent after the compound/element

(s)= solid, (l)= liquid, (aq)= aquaeus, and (g)= gas

I'd show you the way to plot it out to solve, but it's hard when typing, so here's your answer: 4.57*10^29 properly sig figed and everything, hope it helps.[/u]

BaCl2 + Na2SO4= NaCl + BaSO4
Then you can put it in the balancer

not impossible at all

Cl2+ 2KI= 2KCl + I2

Hope it helps

The equation is this:

Ni+ 2C2(NOH)2(CH3)--> Ni[C2(NOH)2(CH3)2]2

All help appreciated, thanks.
