The mixture is placed in a container of larger volume. State whether the amount of G will increase of decrease and explain why.
Decrease; More moles on left; Equilibrium shifts to the right in order to increase the pressure
1 of 5
Explain how pH of a pH 9 solution changed more than that of a pH 4 solution when left open to air.
Reacts with CO2; pH falls; Acidic gas produced
2 of 5
Name the strongest type of interaction between polymer chains.
Hydrogen Bonds
3 of 5
KCN rather than HCN is added to the carbonyl group, Given that Ka for HCN is lower; Suggest why it is not used.
Weak acid so only partially disassociates; CN- very low
