Answer:
Substance A is a base and Substance B is an acid.
According to the experimental results
Double replacement, C6H12 and 9O2 yield two different compounds so its a double replacement equation.
Hello, Lindaparker, a spit could form from a rocky headland where prevailing winds would
blow at an angle to the rocky headland, gradually depositing sand and
shingle at that place. A spit is a permanent land form resulting
from marine deposition and wind deposition. It is usually a long and
narrow accumulation of sand or shingle with one joined to the land and
the other end projecting at a narrow angle out into the sea. Salt marshes sometimes form on the sheltered side of a spit.
Answer : The partial pressure of is 102.3 mmHg.
Explanation :
As per question,
Mass of = 62.9 g
Mass of = 33.2 g
Molar mass of = 18 g/mole
Molar mass of = 62 g/mole
First we have to calculate the moles of and .
Now we have to calculate the mole fraction of and .
Now we have to partial pressure of .
According to the Raoult's law,
where,
= partial pressure of water vapor
= total pressure of gas
= mole fraction of water vapor
Therefore, the partial pressure of is 102.3 mmHg.
