Answer:
0.981atm
Explanation:
According ot Dalton's law total pressure of a mixture of non-reactive gas is equal to sum of partial pressures of individual gases.
total pressure= 1.01at
Number of gases=2
Gases: water vapor and hydrogen
partial pressure of water vapor= 0.029atm
1.01= partial pressure of water vapor+ partial pressure of hydrogen
1.01= 0.029 + partial pressure of hydrogen
partial pressure of hydrogen = 0.981atm
The state of matter with the slowest moving atoms is solid!
The total pressure is calculated as below
Total pressure = partial pressure of (nitrogen +oxygen + argon gas)
= 587 mm hg + 158 mm hg + 7 mm hg = 752 mmhg is the total pressure
When peroxide is swallowed, it generates oxygen bubbles in the stomach. Drinking higher concentrations of hydrogen peroxide can be very dangerous because it can cause tissue burns.
Answer:
Dissolves a chemical sample well at high temperatures.
Does not dissolve a chemical sample well at low temperatures.
Explanation:
Recrystallization involves the dissolution of the solute in a solvent at high temperature. As the solution cools, it becomes saturated and the solute crystallizes out of the solution.
A good recrystallization solvent must only dissolve the solute at high temperature and must not dissolve it at low temperature. Hence, these are the two conditions required for any good recrystallization solvent.
