As a result reductant become oxidized by reducing the oxidant which itself get reduced by accepting the electron from the reductant.
Population density increases
Answer:
0.203 is the mean of the concentration of the HCl solution
Explanation:
You have 5 concentrations. The most appropiate result is the mean of those results. The mean is a statistical defined as the sum of each result divided by the total amount of results. For the results of the problem, the mean is:
0.210 + 0.204 + 0.201 + 0.202 + 0.197 = 1.014 / 5 =
<h3>0.203 is the mean of the concentration of the HCl solution</h3>
Answer:
An element
Explanation:
Elements are not able to be separated, but everything else can, whether that be physically or chemically.
