put cool water over it not cold and cover the burrn
Answer:
D
Explanation:
We can use the mole ratio to calculate the partial pressure. The total number of moles is 0.2 + 0.2 + 0.1 = 0.5 moles
Now, we know that the mole fraction of the argon gas would be 0.2/0.5
The partial pressure is as follows. To calculate this, we simple multiply the number of moles by the total pressure.
0.2/0.5 * 5 = 1.0/0.5 = 2.00atm

Mixture. Mixtures separate, solutions do not.
Use the brass foil to carry the current, because metals conduct electricity well in the solid state.
Dissolve the calcium chloride in water, because ionic compounds conduct electricity well when dissolved.
Pure water, sugar, or methane are not useful because they are covalent compounds and do not conduct an electric current.
What's the question? I don't understand where the problem is.
