HELP plis ! Find the molar masses of the following compounds: SHOW ALL WORK!!!

1) LiI. Li. 7 + I 127

134g/mol

2) PbCO4

Pb =. 1 x 207 =207

C = 1 X 12 = 12

O = 4 x 16 = 64

283 g/mol

3) Mg(OH)2

Mg= 1x 12 = 12

O= 2 x16 =32

H= 2x1= 2

46 g/mol

4) K3PO4

5) (NH4)3PO4

6) C12H22O11

7) Fe2(SO4)3

8) Na3P

9) AgF

10) NH4C2H3O2

**40** points asapessay questions (10 points possible) clear image of next, create your own scenario. it can be one of your own real experiences or one you make up. use imagery in your writing to give your instructor a the setting and an action taking pace in your writing explain the structure and functions of the skin at work in your scenario. !

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

How do you know when a chemical reaction has occurred
