Answer:D. In order to restore equilibrium, the reaction shifts right, towards products
Explanation:
Answer:
Therefore 500 ml of solution have 0.25 mol of NaCl .. = 14.61 g (ans.)
Explanation:
Molar mass Li2CO3 = 73.89 g/mol
Molar mass Li = 6.94g/mol Li = 6.94*2 = 13.88g
% LI = 13.88/73.89*100 = 18.78% perfectly correct.
Answer:
Ca(OH)₂ (aq) + 2NH₄Cl (aq) → CaCl₂ (aq) + 2NH₃ (g) + 2H₂O (l)
Ca²⁺ + 2OH⁻ + 2NH₄⁺ + 2Cl⁻ → Ca⁺² + 2Cl⁻ + 2NH₃ (g) + 2H₂O (l)
2OH⁻ + 2NH₄⁺ → 2NH₃ (g) + 2H₂O (l)
Speed is calculated using the formula distance divided by time. For a distance of 26.2 miles, and a time of 3 hours and 40 minutes, we first convert the time to make it solely in terms of hours. 40 minutes is 2/3 of an hour, so this is a total time of 3 2/3 or 11/3 hours. If we divide 26.2 miles by 11/3 hours, we get a resulting speed of 7.14 miles/hour.
