When it changes phases energy is needednto break down the bonds so that is can change state from one phase to another.
Answer:
E. HCl
Explanation:
Cl atom does not have enough electronegativity to make enough positive charge on H.
To estimate the molar mass of the gas, we use Graham's law of effusion. This relates the rates of effusion of gases with their molar mass. We calculate as follows:
r1/r2 = √(m2/m1)
where r1 would be the effusion rate of the gas and r2 is for CO2, M1 is the molar mass of the gas and M2 would be the molar mass of CO2 (44.01 g/mol)
r1 = 1.6r2
1.6 = √(44.01 / m1)
m1 = 17.19 g/mol
Window cleaner is ammonia dissolved in water. This is an example of a _______.
A higher density (besides H2O) as they have a more rigid structure, they have better conductive abilities than their liquid or gas forms. there are a couple more that i cannot think of at this moment in time.
