What causes pressure

Pressure is caused by collisions of gas molecules with surfaces or other gas molecules.

How much KB is in 1 KB

Well, the obvious answer would be: 1 KB, did you mean: "How many bytes in 1 KB?" if you did then the answer would be: 1024 bytes in 1 KB.

What would heating a sealed glass jar do

Increase the pressure of the gas inside

Why does lowered air pressure allow water to boil at room temperature

Less force pushes down on the liquid, making it easier for gas to escape

What do many bases have in common

they often form hydroxide ions

What is the equation form of the ideal gas law

PV=nRT

D:

What is Ka for H2CO3 aq H aq HCO3 aq

Ka= [h+][HCO3-]/[H2CO3]

What does volatility refer to

the tendency of liquids to form a vapor

A mixture of He Ar and Xe has a total pressure of 2.60atm The partial pressure of He is 0.350atm and the partial pressure of Ar is 0.350atm What is the partial pressure of Xe

Total = 2.60 atm. 2.60-.350atm(He)-.350atm(Ar) = 1.8 atm Xe
