Energy can be conserved by efficient energy use.
Answer: Option A
<u>Explanation:</u>
Energy can be transferred from one form to another, but it cannot be destroyed or created. So it can be conserved if efficiently used. Thus efficient usage of energy lead to conservation of energy. Due to conservation of energy, the forces can be renewable and non-renewable.
So, we should know how the input energy can be completely converted to another form of energy leading to efficient usage of energy without any loss. As if there is no loss, input energy will be equal to output energy leading to 100% efficiency.
I think the most appropriate answer is: the solvent being used in the experiment
<span>To correct for any light absorption not originating from the solute you will need to calibrate the tools with a solution that most similar to the sample.
Blank covete or standard solution can be used, but it was not ideal. By using the solvent as calibration, you can remove the reading from the solvent so your result only comes from the sample.

Molarity of HCl = number of moles/ volume
Number of moles = Molarity of Hcl * volume
No of moles = 0.8 * 18.6 * 10^(-3) = 14.88 * 10^(-3)
From the equation one mole of HCl reacts with one mole of ammonia
Hence number of moles of ammonia = 14.88 * 10^(-3)
From question volume of ammonia = 5 * 10^(-3)
So it follows that Molarity of ammonia = number of moles of ammonia/ volume
Molarity = 14.88 * 10^(-3)/5 * 10^(-3) = 2.976 * 10^(-3 -(-3))
Molarity = 2.976
