What characterizes a heterogeneous mixture
The mixture is made up of different consistencies.
What happens to a solute
It gets dissolved in something else.
Why can liquid boil at a low pressure
Reducing the air pressure allows the molecules to escape
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
How many moles of O2 gas in 1L container
I assume you mean at standard temperature and pressure. Use,
PV = nRT
(1 atm)(1 liter) = n(0.08206 L*atm/mol*K)(298.15 K)
n = 1/24.466
= 0.04 moles oxygen gas
--------------------------------
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
What kind crystalline solid is KCI
What is the volume of oxygen occupied by 2 moles at 1.3 ATM pressure and 300K
Ask us anythingWhich of the following intermolecular forces is the strongest
