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

List four observations that indicate that a chemical reaction may be taking place

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
