Decay is a type of degradation reaction and thus is considered a first order reaction. thus the formula goes like this.
rate constant= 0.693/half life
so here...
rate constant= 0.693/1620 year^-1
There are many combinations because it is not all about the number of chemicals, but also about the size of the strand. The longer the strand the more combinations there are and more variations and various lengths provide various results.
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×
