Answer:
It cant
Explanation:
It can not tell because the size of a human and an object to 2 different sizes. Therefor since they are 2 different sizes they can handle different amounts of temperature.
Answer:
1: [H+] = 0.01 M
2: [H+] = 0.0001 M
3: [H+] = 0.0001 M
Explanation:
Step 1: data given
pH = -log[H+]
pH = pOH = 14
Step 2:
1. A solution with pH = 2.0
pH = 2
-log[H+] = 2.0
[H+] = 10^-2
[H+] = 0.01 M
2. A solution with pH = 4.0
pH = 4
-log[H+] = 4.0
[H+] = 10^-4
[H+] = 0.0001 M
3. A solution with pOH = 10.0
pH = = 14 - 10 = 4
pH = 4
-log[H+] = 4.0
[H+] = 10^-4
[H+] = 0.0001 M
Answer is beryllium.
The electronegativity trend is that it increases from left to right in a period and from bottom to top in a group. This is why fluorine has the highest electronegativity out of all the elements. So since beryllium is at the very top of the group, it has the highest electronegativity
Explanation:
Assuming that moles of nitrogen present are 0.227 and moles of hydrogen are 0.681. And, initially there are 0.908 moles of gas particles.
This means that, for 
moles of 
+ moles of 
= 0.908 mol
Since, 2 moles of = 
= 0.454 mol
As it is known that the ideal gas equation is PV = nRT
And, as the temperature and volume were kept constant, so we can write
= 
= 
= 
= 5.2 atm
Therefore, we can conclude that the expected pressure after the reaction was completed is 5.2 atm.
Vapor pressure is the pressure which is exerted by the vapors of a liquid in equilibrium with the liquid. Vapor pressure depends on the boiling point; lower the boiling point higher will be the vapor pressure.
Based on the given compounds:
rubbing alcohol is polar and has the strongest intermolecular force of attraction followed by relatively polar ether and finally the non-polar propane.
The increasing order of boiling point will be:
propane < diethyl ether < rubbing alcohol
Thus, the increasing order of vapor pressure will be:
rubbing alcohol < diethyl ether < propane
Ans : F
