I have the same question why can’t I accept this comment HELPPP 3737
Answer:
to mi understanding iz fusion reaction
Answer:
Some of the calcium carbonate remained stuck to the side of the glassware after filtering
Some of the calcium carbonate spilled when measuring its mass
Explanation:
The percent yield is obtained from;
Actual yield/Theoretical yield * 100
Usually, the actual yield is less than the theoretical yield thereby making the percent yield less than 100%.
In the case of this particular reaction; when some calcium carbonate remains stuck on the glassware or some calcium carbonate is spilled during weighing, the actual yield of product obtained from the reaction becomes less than the theoretical or calculated yield hence the percent yield becomes less than 100%.
I'm not sure if this is the exact answer for I do not learn this in school yet. But I hope this helps!

Answer:
— Washing with soap and water is an effective way to destroy and dislodge many microbes
Explanation:
- Soap actually kill germs on our hands, it breaks them up and removes them
- .But soap molecules have two different ends to them.
- One end is attracted to water molecules – this is called hydrophilic
- – and the other end loves oil and fat molecules – this is called hydrophobic.
- Soap is able to bind to the oils on our hands, and then mix with the water to wash all the germs away.
