Answer:
if you add a neutron to lithium-7 it becomes a compound nucleus of lithium-8
Explanation:
firstly find for the molar mass of kcl and molar mass of k
and then
molar mass of k = x
molar mass of kcl= 40
cross mutiply and then simplify you will get your answer
Scientists use the scientific method all the time to help them understand things about certain topics. The scientific method is a list of steps that are used before, during, and after the experiment. The scientific method can help prove hypothesis about things and can tell you the outcome of the experiment.
Answer:
Methanol would be used as a reagent in excess, since it is a very low-cost solvent. For product isolation, the first thing to do is remove the methanol through a distillation process. The residue produced can be dissolved in diethyl ether. Using a NaHCO₃ solution, extraction is performed. When it separates into two phases, the product will be in the ether and the reagent in the aqueous phase. The ether can also be removed by distillation, and at the end of this process you will have the product you want.
