What does a smaller uncertainty in chemistry mean?

Give one reason why something would have a smaller uncertainty.

A reaction mixture is at equilibrium. What happens when the amount of one of the reactants is increased? The equilibrium state is lost and cannot be restored. The amount of the other reactant also increases. The amount of the product also increases.

The standard reduction potential for a substance indicates how readily that substance gains electrons relative to other substances at standard conditions. The more positive the reduction potential, the more easily the substance gains electrons.

Which piece of information is not necessary to calculate the force of gravity between two objects, A and B? A. The mass of object A. B. The mass of object B. C. The velocities of A and B. D. The distance between A and B.
