Q: What state is achieved when the forward and reverse reactions proceed at equal rates? Read this paragraph and choose the correct option from the provided answers: At equilibrium, the forward and reverse reactions proceed at equal rates. The driving force in each direction is equal, because the free energy of the reactants and products under equilibrium conditions is equivalent (G = 0). We also know that, at equilibrium, Q = K eq . For a reaction that has reached equilibrium, the equation above becomes the following:. Choices: - neutrality - equality - constant - equilibrium A:
equilibrium

Q: Acetone is the simplest type of what organic compound that involves a carbonyl in which the carbon atom makes single bonds with two other carbon atoms? Read this paragraph and choose the correct option from the provided answers: A ketone involves a carbonyl in which the carbon atom makes single bonds with two other carbon atoms. Ketones undergo most of the same reactions as aldehydes, but they tend to be slightly less reactive. The simplest ketone is acetone, in which the carbonyl carbon is bonded to two CH 3 groups. This ketone is commonly used to remove fingernail polish and serves as an industrial solvent. Methyl ethyl ketone is used as a paint stripper and a solvent. Ketones are also used in the production of various polymers, either as a building block or as a solvent. Choices: - enzyme - protein - anion - ketone A:
(Answer)
ketone

Ques: Q: What happened to chemical reactions when temperature increases? Read this paragraph and choose the correct option from the provided answers: Temperature increases. Chemical reactions are faster at higher temperatures. Choices: - it slows down for a short time then speeds up - it stays the same - it becomes slower - it became faster A:
Ans: it became faster

(Q).
Q: Unlike wood and glass, steel is an example of a material that responds to what force? Read this paragraph and choose the correct option from the provided answers: Magnetism is the ability of a material to be attracted by a magnet and to act as a magnet. No doubt you've handled refrigerator magnets like the ones in Figure below . You probably know first-hand that they stick to a metal refrigerator but not to surfaces such as wooden doors and glass windows. Wood and glass aren't attracted to a magnet, whereas the steel refrigerator is. Obviously, only certain materials respond to magnetic force. Choices: - kinetic - electromagnetic - thermal - magnetic A:
(A).
magnetic

Ques:Q: What does hair get its color from? Read this paragraph and choose the correct option from the provided answers: 5.2 Accessory Structures of the Skin Accessory structures of the skin include hair, nails, sweat glands, and sebaceous glands. Hair is made of dead keratinized cells, and gets its color from melanin pigments. Nails, also made of dead keratinized cells, protect the extremities of our. Choices: - elasticity pigments - stimulating pigments - fluorescent pigments - melanin pigments A:

Ans:melanin pigments
