The maximum concentration (in m) of calcium ions[] in the given solution is 6.2×
The balanced equillibrium equation is ,
(s) ↔ (aq) + (aq)
From the reaction equation above, the formula for Ksp:
Ksp = [][ ] = 3.4×
We know the value for [ ] , so we can solve for []as:
( 3.4×) = [] (0.055)
[] = 61.8×
[] = 6.2×
Therefore, the maximum concentration (in m) of calcium ions[] in the given solution is 6.2×

The carbon atom reduced in the transformation of chloromethane to methyllithium.
The reaction between chloromethane and lithium form methyllithium.
→
In above reaction, methyllithium is formed by the dispersing of lithium metal and adding chloromethane .
The carbon atom in chloromethane is partial positive charge because chlorine is high electronegative atom. The carbon atom in methyllithium is partial negative charge because carbon is more electronegative than lithium.
So, in above reaction two lithium metal donate two electron ( each lithium donate one electron) to the carbon atom(having positive charge) of chloromethane and get negative charge in methyllithium .
The gain of electron is reduction. So,The carbon atom reduced in the transformation of chloromethane to methyllithium.

Just divide!
60 seconds = 1 min
60 mins = 1 hour
1987 seconds divided by 60 seconds = 33.11 minutes
Your answer would be 33 minutes and 11 seconds
(2) a base because they accept H+ ions. NH3 is the conjugate base of NH4+.
