It took 4.5 minutes for 1.0 l helium to effuse through a porous barrier. how long will it take for 1.0 l cl2 gas to effuse under
serious [3.7K]
When The rate of effusion is inversely proportional to the √molar mass of the substance.
and we have R(He) = 1L / 4.5 min so,
R(He)/R(Cl2) = (molar mass of Cl2/ molar mass of He)^0.5
and when we have the molar mass of Cl2 = 70.9  & the molar mass of He = 4
so by substitution:
(1L/4.5 min)/ R(Cl2) = (70.9 / 4)^0.5
(1L/4.5 min) / R(Cl2) = 4.21
∴R(Cl2) = (1L/4.5 min) / 4.21 = 1L/ (4.5*4.21)min = 1 L / 18.945 min
∴Cl2 will take 18.945 min for 1 L to effuse under identical conditions

the empirical formula of a compound is NO2. it's molecular mass is 92g/mol. What is its molecular formula?
lesantik [10]
The molecular formula:
N_x(O_2)_x

M_{N_x(O_2)_x}=x \times M_N + x \times 2 \times M_O \\ \\
m_N=14 \ \frac{g}{mol} \\
m_O=16 \ \frac{g}{mol} \\ M_{N_x(O_2)_x}=92 \ \frac{g}{mol} \\ \\
92=x \times 14+x \times 2 \times 16 \\
92=14x+32x \\
92=46x \\
\frac{92}{46}=x \\
x=2 \\ \\
N_2(O_2)_2 \Rightarrow N_2O_4

The molecular formula is N₂O₄.

These reactions can also be reversed, breaking the large molecules into its individual molecules. what substance would need to b
lesantik [10]
The appropriate response is water. This reversible reaction can be broken into two responses. These two responses are happening all the while, which implies that the reactants are responding to yield the items, as the items are responding to deliver the reactants. Crashes of the responding atoms cause substance responses in a shut framework.

Which of the following statements will decrease the amount of work the system could perform? (a) Add to the solution (b) Add sol
Dmitry_Shevchenko [17]

Answer:

Increase the concentration of the solution

Explanation:

Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration. For instance, if your lemonade was too tart, you would add more water to decrease the concentration
