If the cup of water contained hot water. Sugar will dissolve a lot slower if it was in room temperature and even slower if it was in cold water.
<span>If you overshoot the endpoint in titration of the KHP, an error will happen in your calculations for the molarity of NaOH you are standardizing. For this, a neutralzation reaction happens where amount of acid should be equal to amount of base. Adding more of the base needed to reach the equivalence would mean you have higher volume which will make the calculated concentration of NaOH lesser.</span>
Answer:
1 mole of water (H2O)
Explanation:
Water has a chemical formula of H2O, there will be 2 moles of hydrogen in every mole of water.
In one mole of water, there will exist approximately 6.02×10^23 water molecules.
So, there will be a total of 6.02×10^23×2≈1.2⋅10^24 hydrogen atoms.
1. air components change from place to place, while water will just stay the same
2. Water doesn't have nor show individual properties, but air does show that it has it's own property
3. You can separate different gases from air physically, but with water you must pass electricity through it.
Don't take my word for it, this is just what I learned back in middle school.
