Answer:The substance is Biodegradable
Explanation:
When something is biodegradable it can be broken down by organical processes or decomposers.
Answer:
The electrons are supplied by the species getting oxidized. They move from anode to the cathode in the external circuit. The external battery supplies the electrons. They enter through the cathode and come out through the anode
The answer should be A.
Hope this helps :-)
Answer:
Approximately .
Explanation:
Note that both figures in the question come with four significant figures. Therefore, the answer should also be rounded to four significant figures. Intermediate results should have more significant figures than that.
<h3>Formula mass of strontium hydroxide</h3>
Look up the relative atomic mass of , , and on a modern periodic table. Keep at least four significant figures in each of these atomic mass data.
Calculate the formula mass of :
.
<h3>Number of moles of strontium hydroxide in the solution</h3>
means that each mole of formula units have a mass of .
The question states that there are of in this solution.
How many moles of formula units would that be?
.
<h3>Molarity of this strontium hydroxide solution</h3>
There are of formula units in this solution. Convert the unit of volume to liter:
.
The molarity of a solution measures its molar concentration. For this solution:
.
(Rounded to four significant figures.)
