Q: Q: What reaction means, literally, "splitting with water"? Read this paragraph and choose the correct option from the provided answers: Esters are neutral compounds, unlike the acids from which they are formed. In typical reactions, the alkoxy (OR) group of an ester is replaced by another group. One such reaction is hydrolysis, literally "splitting with water. " The hydrolysis of esters is catalyzed by either an acid or a base. Acidic hydrolysis is simply the reverse of esterification. The ester is heated with a large excess of water containing a strong-acid catalyst. Like esterification, the reaction is reversible and does not go to completion. Choices: - aqueous - hydroxis - fission - hydrolysis A:
A: hydrolysis

Q: Q: What is the term for the force applied to a wheel and axle? Read this paragraph and choose the correct option from the provided answers: In a wheel and axle, force may be applied either to the wheel or to the axle. This force is called the input force. A wheel and axle does not change the direction of the input force. However, the force put out by the machine, called the output force, is either greater than the input force or else applied over a greater distance. Choices: - velocity force - momentum - output force - input force A:
A: input force
