Answer:

Energy of compressed string-potential energy (because it has ability to do work).

Energy of coal -potential energy (because it has ability to do work).

Energy of guitar string when plucked- kinetic energy(because the string is moving).

Energy from a flashlight when on - kinetic energy (because the light waves are in motion).

What molecule is needed to digest milk?
xxMikexx [17]

Answer:

For example, the sugar found in milk is called lactose. With the aid of the enzyme, lactase, the substrate, lactose, is broken down into two products, glucose and galactose. People who don't make enough lactase have trouble digesting milk products and are lactose intolerant.

The rate law for the reaction
juin [17]

Explanation:

Since, the given reaction is as follows.

              2NO(g) + Cl_{2}(g) \rightarrow 2NOCl(g)

Hence, rate law of the reaction is as follows.

               R = k[NO][Cl_{2}]

As it is known that rate of a reaction depends on the initial concentration of products. So here, the rate of reaction will depend on the concentration of NO and Cl_{2}. Since, power of the concentrations of each of these is equal to 1. Therefore, order of the reaction is equal to 1 + 1 = 2.

According to the rate law, reactants involved in the rate determining step are NO and Cl_{2}. Hence, first step of the mechanism is the rate determining step.

Also, according to the rate of reaction doubling the concentration of NO will double the rate of reaction.

The number of reactants taking part in a single step of the reaction is known as molecularity of the reaction. Therefore, molecularity of the first step of the reaction is 2.

Both the given steps are not termolecular.

Which method can you use to investigate the compressibility of a gas?
Alina [70]

Answer: Option (b) is the correct answer.

Explanation:

It is known that in a gas, molecules are away from each other due to more kinetic energy between its particles. As a result, there are more number of collisions between them.

So, when we apply pressure on a gas then its molecules come closer to each other. Due to which there occurs decrease in its volume.

Thus, we can conclude that to investigate the compressibility of a gas increase the pressure on it.
