Answer:
The differences in their data are not significant.
Answer:
The correct option is A.
Explanation:
Isomers are molecules with the same formula but different structure. If you look at the previous structures and count the number of C and H, you find that A and the molecule from the question has the same number of C and H, but their structures are different.
<em>Answer:</em>
The equlibrium concentration sof Ca+2 ion willl be 4.9×10∧-3 M
<em>Data Given:</em>
Ksp of CaSO4 = 2.4 × 10∧-5
CaSO4 ⇔ Ca+2 + SO4∧-2
<em>Solution:</em>
Ksp = [Ca+2].[ SO4∧-2]
2.4 × 10∧-5 = [x].[x]= x²
x = 4.9×10∧-3 M
<em>Result:</em>
- The conc. of Ca+2 ion is 4.9×10∧-3 M
