Answer: Answer:- C. The container contains 8 grams of liquid water and no ice.
Explanation:
The atoms in a metal form a matrix in which their outer electrons can move freely.
Answer:
A gas made up of homonuclear diatomic molecules escapes through a pinhole .533 times as fast as Ne gas. Write the chemical formula of the gas.
Molar mass of Ne gas is 39.1 g/mol
.533= sqrt(39.1/x)
Sq (0.533) = 20.18/x
0.284 = 20.18/x
x = 71.034 g/mol
Where the chlorine has a molar mass of = 35.5g and molar mass of Cl2 gas = 2 × 35.5 = 71 g/mol
Explanation:
Graham's law: Rate1/Rate2 = sqrt(M2/M1) where M is the molar mass
Thus we have (Rate of x)/(Rate of Ne) = sqrt((Molar mass of Ne)/(Molar mass of x))
From the question (Rate of x)/(Rate of Ne) =0.533
and sqrt((Molar mass of Ne)/(Molar mass of x)) = sqrt(39.1/(Molar mass of x))
.533/1= sqrt(39.1/x)
Sq (0.533) = 20.18/x
0.284 = 20.18/x
x = 71.034 g/mol
Hence a compatible gas is chlorine Cl2 with molar mass of
71 g/mol
Answer:
In Charles law, temperature and volume of the gas are kept at constant pressure. Where as in Boyle's law, pressure and volume of the gas are kept at a constant temperature. In Boyle's law, pressure and volume vary inversely where as, in Charles law, pressure and volume vary directly.
Answer:
The SI base unit for amount of substance is the mole. 1 grams NaOH is equal to 0.025001806380511 mole.
