MgCl2 + AgNO3 → AgCl + Mg(NO3)2
Law Incorporation [45]

Answer:

MgCl2 + 2AgNO3 → 2AgCl + Mg(NO3)2

Explanation:

I'm assuming you want to balance it so...

The first thing I see is that there are two chlorines on the reactant side and one on the product side

Adding a coefficient of 2 would get 2AgCl2

Now there are two silvers on the reactant side, so add a 2 to AgNO3 on the products side. Now they are all balanced.

If that is not what you are looking for let me know!

What is the mass in grams of 2.0 moles of NO2
mote1985 [20]
Use your periodic table to get 1 mol. Look up the atomic masses. I'll round the numbers since every periodic table is different.
 
N = 14
O2 = 2 *16
Total = 30 grams / mol


Therefore 2 mols = twice as much = 60 grams.
