Hey, The answer is 11.12 I hope this helps you out
Answer : The correct chemical equation is:
![2NaBr(aq)+Pb(NO_3)_2(aq)\rightarrow PbBr_2(s)+2NaNO_3(aq)](https://tex.z-dn.net/?f=2NaBr%28aq%29%2BPb%28NO_3%29_2%28aq%29%5Crightarrow%20PbBr_2%28s%29%2B2NaNO_3%28aq%29)
Explanation :
Balanced chemical equation : It is defined as the equation in which the atoms of individual elements present of reactant side must be equal to the product side.
According to the question, when sodium bromide reacts with lead nitrate then it reacts to give sodium nitrate and lead bromide as a products.
The balanced chemical equation will be:
![2NaBr(aq)+Pb(NO_3)_2(aq)\rightarrow PbBr_2(s)+2NaNO_3(aq)](https://tex.z-dn.net/?f=2NaBr%28aq%29%2BPb%28NO_3%29_2%28aq%29%5Crightarrow%20PbBr_2%28s%29%2B2NaNO_3%28aq%29)
Answer:
"After 1 half-life there will be 50% of the original isotope, and 50% of the decay product.
After 2 half-lives there will be 25% of the original isotope, and 75% of the decay product.
After 3 half-lives there will be 12.5% of the original isotope, and 87.5% of the decay product.
After 4 half-lives there will be 6.25% of the original isotope, and 93.75% of the decay product." -Stephen Frantz, Former Director of the Reed College Nuclear Reactor
