Answer:
1/8
Explanation:
From;
Nt/No = (1/2)^t/t1/2
N= amount of dimethylether present at time t
No= amount of diethylether present at time t=0
t= time taken for N molecules of diethylether to remain = 4710 seconds
t1/2 = half-life of diethylether = 1570 seconds
Substituting values;
Nt/No = (1/2)^4710/1570
Nt/No = (1/2)^3
Nt/No= 1/8
Hence after 4710 seconds only 1/8 molecules of dimethylether will remain
AlBr3 + 3LiOH —> Al(OH)3 + 3LiBr

Answer:
The two products that will be formed are:
Ca(NO3)2
NaI
Explanation:
When NaNO3 reacts with CaI2, double substitution reaction takes place.
This means that I2 and NO3 will each substitute the other.
The chemical reaction used to explain this is as follows:
2NaNO3 + CaI2 .........> 2NaI + Ca(NO3)2
