The correct option is A.
Metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. The malleability of metals refers to their ability to withstand bending and hammering without breaking. Metals are not dull, neither are they brittle, those are the properties of non metals.
Answer:
The change in entropy of gas is
Explanation:
n= Number of moles of gas
Change in entropy of gas =
From the given,
Let "T" be the initial temperature.
Therefore, The change in entropy of gas is
When it gains an electrons is negatively charged so in this case I think it will be. -ion
<u>Answer:</u> The total vapor pressure of the solution is 81.3 mmHg
<u>Explanation:</u>
To calculate the total pressure, we use the equation given by Dalton and Raoults, which is:
where,
= total vapor pressure
We are given:
Mole fraction of benzene = 0.580
Mole fraction of toluene = (1 - 0.580) = 0.420 (Total mole fraction is always equation to 1)
Vapor pressure of benzene = 183 mmHg
Vapor pressure of toluene = 59.2 mmHg
Putting values in above equation, we get:
Hence, the total vapor pressure of the solution is 81.3 mmHg
