Answer:
Na₂CO₃.
Explanation:
- <em>Le Châtelier's principle</em> states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
The compound that has a common ion effect is Na₂CO₃.
- When it is added to the solution, it is dissolved to produce Na⁺ and CO₃²⁻ which increases the concentration of CO₃²⁻ that will increase the concentration of the products side, so the reaction will be shifted to the left side to suppress the increase in the concentration of CO₃²⁻.
Answer:
C₅H₁₂.
Explanation:
- The hydrocarbon is burned in excess of oxygen to give CO₂ and H₂O.
- <em>The no. of moles of CO₂ produced = mass/molar mass </em>= 1.53 g/44.0 g/mol = <em>0.03477 mol.</em>
<em>Which is corresponding to 0.03477 mol of C.</em>
<em />
- <em>The no. of moles of H₂O produced = mass/molar mass</em> = 0.756 g/18.0 g/mol = <em>0.042 mol.</em>
<em>which corresponds to (0.042 x 2) = 0.084 moles of hydrogen.</em>
<em />
- The ratio of the number of moles of hydrogen to carbon in the composition of the compound will be 0.084 / 0.03477 = 2.4 = 12/5.
- <em>Therefore, the empirical formula of the compound under consideration is C₅H₁₂.</em>
