Answer:
104.56cm³
Explanation:
Mass=826g
Density =7.9g/cm³
Volume =Mass /Density
Volume =826/7.9
Volume =104.56cm³
D. They react readily with oxygen in the air
Answer: 4.4 x 10^-7
The dissociation equation for this reaction is:
MgCO3 (s) → Mg+2 (aq) + CO3-2 (aq)
(Here 0.08 >>> x )
So the solubility MgCO₃ in a solution that containing 0.080 M Mg²⁺ is 4.4 x 10^-7
ANSWER:
I think its B.
