After the water is boiled off, the mass is 9.7 grams, so find the weight of the water.
12.98 - 9.7 = 3.28g H2O
Find how many moles of CuSO4 and H2O you have.
If there are about 18g per mole of H2O
3.28/18 = .1822 moles of H2O
If there are about 160g per mole of CuSO4
9.7/160 = .0606 moles of CuSO4
.1822/.0606 = 3
Ratio of H2O to CuSO4 = 1:3
Formula
<span>CuSO4.3H2O
</span>
Full Name
<span>Copper (II) Sulphate Trihydrate</span>
Answer:
Explanation:
for spontaneous reaction,
ΔG is negative
K>1
E > 0
cell A:
ΔG and EO suggests that reaction is spontaneous. But K is less than 1.
Hence K is wrong
cell B:
ΔG and EO suggests that reaction is non spontaneous .But K is greater than 1.
Hence K is wrong
cell C:
E and K suggest than reaction is non spontaneous but ΔG suggest that reaction is spontaneous.
Hence ΔG is wrong
More specifically the cell wall prevents the vacuole from getting to large and making the plant cell burst.
