b) 0.15 moles CaO (molar ratio of CaO to CaCO3 is 1:1)
c) 8.4 grams CaO (0.15 moles)*(56 grams/mole)
2. a) 0.274 moles Na2O (17g/62 grams/mole)
b) 46.6 grams NaNO3 (2 moles NaNO3/1 mole Na2O)*(0.274 moles Na2O)*(85 g/mole NaNO3)
Answer:Um... I think 5000 i am not really sure
Explanation: I Dont Really Know
Answer:
False
Explanation:
There is a water cycle wherever there is water. If it is cold, the water cycle will just be very slow.
The answer should be A, they turn litmus paper blue!
The vapor pressure at the new temperature can be obtained as 0.074 atm.
<h3>What is the vapor pressure?</h3>
The term vapor pressure has to do with the pressure that accumulates owing to the fact that some of the liquid is leaving the solution and gets to the top of the container.
Now we have the formula;
ln(P2/P1) = -ΔHvap/R(1/T2 - 1/T1)
P2 = final pressure
P1 = initial pressure
ΔHvap = Enthalpy of vaporization
T2 = final temperature
T1 = initial temperature
ln(P2/0.2020) = -20.94 * 10^3/8.314(1/240.9 - 1/261.5)
ln(P2/0.2020) = -2518.6(0.0042 - 0.0038)
ln(P2/0.2020) = -1.00744
Taking the exponential of both sides;
P2/0.2020 = e^-1.00744
P2 = e^-1.00744 * 0.2020
P2 = 0.074 atm
