Which of the following statements correctly describe a chemical change? Select all that apply!
| Only the physical form of the substance is changed during a chemical change. |
| A chemical change involves a change in phase without a change in composition. |
| The physical properties of the substance are changed during a chemical change. |
| The composition of the substance is altered during a chemical change. |
Homework Answers
1. Is a physical change, as the physical property changes.
2. This is also a physical change Example, water as ice water and vapour are easily convert into one another.
3. This is also a physical change
4. Yes this is a chemical change, because in chemical change composition is changes of the substance

Which of the following statements correctly describe melting and melting point? Select all that apply. Check all that apply. The temperature of a solid rises steadily during the melting process. At the melting point of a substance the solid and liquid phases are in equilibrium Pressure changes have little effect on the melting point of a substance. During melting the kinetic energy of the particles increases dramatically

Which of the following statements correctly describe the transition state of a reaction? Select all that apply. Check all that apply The transition state species is highly unstable. The transition state only exists at the instant of highest potential energy in the reaction The transition state species is either the reactant or product depending on the reaction. The energy required to form the transition state is the enthaloy change of the reaction (AH, Do you know the

Which of the following statements correctly describe the half-life of a reaction? Select all that apply. Check all that apply. The half-life of a first-order reaction is independent of the initial concentration. The half-life of a reaction is related to its rate constant. The half-life of a reaction is the time taken for (A)to drop to half its original value. A chemical reaction is complete after two half-lives have passed. The half-life of a reaction is always a constant value.

Which of the following statements is true about chemical equilibrium? Select all that apply. At chemical equilibrium, the reactants have been completely consumed. At chemical equilibrium, both reactions stop completely. At chemical equilibrium, the concentrations of the species involved in the reaction stay constant (in the absence of an external perturbation). At chemical equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.
