Answer: 1 mole of water (H2O)
Poor people get money when we eat the rich or something along those lines
Elimanate B then C and then it should be A or D just sayin i could be wrong about this i hope im right
Answer:
3Ba(OH)2 + 2H3PO4 —> Ba3(PO4)2 + 6H2O
Explanation:
Ba(OH)2 + H3PO4 —> Ba3(PO4)2 + H2O
There are 3 atoms of Ba on the right side and 1atom on the left side. It can be balance by putting 3 in front of Ba(OH)2 as shown below:
3Ba(OH)2 + H3PO4 —> Ba3(PO4)2 + H2O
There are 2 atoms of P on the right side and 1atom on the left. It can be balance by putting 2 in front of H3PO4 as shown below:
3Ba(OH)2 + 2H3PO4 —> Ba3(PO4)2 + H2O
Now, there are a total of 12 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 6 in front of H2O as shown below:
3Ba(OH)2 + 2H3PO4 —> Ba3(PO4)2 + 6H2O
Now the equation is balanced as the numbers of the atoms of the different elements present on both sides are equal
Answer:
Vapor pressure for solution is: 20.48 Torr
Explanation:
Formula to be applied: ΔP = P° . Xm
ΔP = P° - P'
P° → Vapor pressure of pure solvent
P' → Vapor pressure of solution
Xm = Mole fraction.
Let's replace data → 26.5 Torr - P' = 26.5 Torr . 0.227
P' = - (26.5 Torr . 0.227 - 26.5 Torr) →
