If we work it out with direct proportions, the vapor pressure of propanone is 56 degrees Celsius. The atmospheric pressure is about 101 kPa. If the vapor pressure is equal to the atmospheric pressure, the substance boils. Therefore, if we hold a linear proportion, 45/56 = x/101. 56x = 101*45, x = 101*45/56 = 81. The closest choice here is (3) 70 kPa.

Answer:
The answer to your question is: 5 friends
Explanation:
Data
Larry bought 12 1/2 pounds of candy
gave each friend 2 1/2 pounds
number of friends = ?
Process
Convert mixed fractions into improper fractions
12 1/2 = (24 + 1) / 2 = 25 /2
2 1/2 = (4 + 1) / 2 = 5/2
Divide the fractions
= 
= 5
Larry gave candies to 5 of his friends
Answer:
It is correct because iron is more reactive than silver.
Explanation:
Decreasing Pressure. The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle's law. <em>Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.</em>
