Answer:
Explanation:
To know the temperature at which KCl dissolves in water we need to refer to the general solubility curves.
In the case of , of it will dissolve in of water at a minimum temperature of .
So, the the minimum temperature needed to dissolve 35 grams of KCl in 100 grams of water is .
Answer:
86.9 g
Explanation:
Use the conversion factor: 4.82 mol H2O x (18.02g H2O/1 mol H2O)
The moles cancel out so we have to multiply 4.82 x 18.02 = 86.9
The answer is 3 sig. figs.
Answer:
I don't know if this will really help you but I'll try to explain it
Explanation:
it wants you tell some things you see on the graph. Some examples you can say is what kind of bond it is and things like that. You can use a periodic table
I think the answer is B because Sound travels about 1,500 m/s underwater, and sound travels about 332 m/s in air. Sound underwater travels faster and longer in water. The particles are more tightly packed together, so sounds travel faster through water.
Answer:
The Dew Point temperature is always lower than the Dry Bulb temperature and will be identical with 100% relative humidity (the air is at the saturation line). As air temperature changes the Dew Point tends to remain constant unless water is added or removed from the air.
