Answer:
Proton is a sub atomic particle while oxygen is an atom ....
Answer:
Option B
Explanation:
Salt is a non-volatile solute and hence adding salt will increase the boiling point of water and hence reduce the vapor pressure. While on the other hand, adding more water will require more time to boil and hence produce vapor and thus the vapor pressure. Shaking will also not help in increasing the vapor pressure. Thus, only increasing the temperature of the water will create more vapors at a faster rate and hence increase the vapor pressure.
Thus, option B is the correct answer
Answer:
It is basic and has a pH of 9.8.
Explanation:
pOH = 4.2
we will determine its pH.
pOH + pH = 14
pH = 14 - pOH
pH = 14 - 4.2
pH = 9.8
According to pH scale the the pH lower than 7 is consider acidic while pH of seven is neutral and pH greater than 7 is basic.
The given solution has pH 9.8 it means it is basic.
Answer:
If you are not eye to eye with the miniscus you would be reading wrong because you have to read right from the middle because of you won’t you’d always be off
Explanation:
Answer:
C₃H₆ + H₂O = C₃H₈O
Explanation:
Hydration reactions (reactions involving converting an alkene to alcohol) have only one product, so there will be no byproduct along with propanol.
