Answer: Letter D represents the wavelength of the wave.

Explanation: We are given a wave in the image. Wave comprises of crests and troughs.

Wavelength of a wave is defined as the distance between the two crests or two troughs or one crest and one trough.

And here letter D is the distance between the two troughs. Hence, this indicates the wavelength of the wave.

D represents the wavelength in your problem. The wavelength is the measurement between two crests and can be measured on the bottom crest or the top crest.

A pharmacist measures the mass of a powdered drug. The mass is 506 mg . What is the mass in grams? Write your answer as a decima
otez555 [7]

Answer:

0.506 g

Explanation:

we know that one miligram is equal to 0.001 g or we can say that  one gram contain thousand miligram. so,

if the mass of drug is 506 mg then to convert it into gram we have to divide 506 mg into 1000.

LenaWriter [7]

If a chemical reaction catalyzed by an enzyme is being carried out, and there is a sudden, drastic decrease in temperature, the thing that will most likely to happen next is going to be the :

“enzyme activity will decrease, and the reaction will proceed very slowly, or possibly not at all.“

Explanation:

This compliance is required to how enzymes bind to other molecules and cause chemical reactions to occur on those molecules. Lowering the temperature reduces the motion of molecules and atoms, expecting this compliance is reduced or lost. As the temperature decreases, so do enzyme activity. While higher temperatures do increase the activity of enzymes and the rate of reactions,

A student observes the combustion (burning) of propane (C3H8). Because of the heat and light it generates, the student concludes
insens350 [35]

Answer:

The student's conclusion is not correct

Explanation:

Activation energy is the minimum amount of energy required for a reaction to occur. All reactions require there activation energy to be met before the reaction can proceed. When the temperature of a reaction is increased, the kinetic energy of the reactant molecules increases; colliding more with each other, which makes them "surmount" the activation energy of the reaction faster as compared to a lower temperature.

In combustion, there is burning of an hydrocarbon (in this case propane) in excess oxygen. The burning assists in increasing the kinetic energy of the reactant particles which in turn easily surmounts the activation energy of the reaction  by colliding (effective collision) more with oxygen. So, the reaction has an activation energy but the activation energy has been met and passed and hence the reaction is proceeding faster.

Increasing the temperature of a reaction is one of the ways of increasing the rate of a chemical reaction.
