Example chemistry quiz questions with answers

What is the pH of a neutral aqueous solution at 25 °C?7. Pure water dissociates into equal concentrations of H+ and OH- ions, so neither dominates.

Which type of bond forms when atoms share electron pairs?A covalent bond. Shared electron pairs hold the atoms together, unlike the electron transfer in ionic bonds.

True or false: Adding a catalyst shifts the equilibrium position of a reaction.False. A catalyst speeds up the forward and reverse reactions equally, so equilibrium is reached faster but its position does not change.

What is the molar mass of CO2 (C = 12.01, O = 16.00 g/mol)?44.01 g/mol. One carbon at 12.01 plus two oxygen atoms at 16.00 each gives 44.01.

Why does increasing pressure shift N2 + 3H2 ⇌ 2NH3 to the right?There are 4 gas molecules on the left and 2 on the right, so the system shifts toward fewer molecules to reduce the pressure increase.
