Answer:
Mole fraction H₂ = 0.29
Partial pressure of H₂ → 88.5 kPa
Explanation:
You need to know this relation to solve this:
Moles of a gas / Total moles = Partial pressure of the gas / Total pressure
Total moles = 3 mol + 7.3 mol → 10.3 moles
Mole fraction H₂ → 3 moles / 10.3 moles = 0.29
Mole fraction = Partial pressure of the gas / Total pressure
0.29 . 304 kPa = Partial pressure of H₂ → 88.5 kPa
Yahoo has the answer to that question. because i looked it up on yahoo..
Answer:
compound is a pure substance while mixture is an impure substance
Compounds are always homogeneous whereas mixtures can be homogeneous or heterogeneous
in a compound, the ingredients are present in definite proportion while the constituents in a mixture are in variable proportion
the properties of compound are identical to the properties of it's ingredients unlike mixture wherein the properties of ingredients and the mixture are same
.. compounds are boiled or melted at definite temperature while mixture do not have a fixed melting and boiling point
