Two substances A and B react with each other in such a way that one-half of A remains after 25 min and one-fourth of A remains a

fter 50 min. Doubling the concentration of B while keeping the concentration of A fixed doubles the rate of the reaction. This reaction is
a. first-order in both A and B.
b. second-order in A and first-order in B.
c. zero-order in both A and B.

Answer:

a. first-order in both A and B.

Explanation:

In order to determine the kinetics of reaction let us consider the given data

a) Doubling the concentration of B while keeping the concentration of A fixed doubles the rate of the reaction. : it means the reaction is first order reaction with respect to reactant B.

b) The half life is the time required to complete the reaction by half way.

As with time one half of A remains and after equal time one fourth of A remains it means again the order of reaction is first with respect to A also.

There is no effect on the half life if we are decreasing the initial concentration of A also.

Espresso Coffee House is designing a coffee mug that keeps liquids hot. The research department tested several different materia
raketka [301]

Answer:

This question is incomplete

Explanation:

This question is incomplete because the result of the described experiment would have better determined the type of scientific explanation to profer. However, the type of material that will preserve the relative hotness or temperature of the hot coffee for the longest time will be a material than can resist heat transfer. These materials tend to keep hot substances hot by not allowing the heat of the coffee to be conducted or pass through it. These materials are mostly insulators or made by placing an insulator between two heat conductors.

Generally, heat is usually transferred from a region of higher concentration to a region of lower concentration, hence when the heat is denied of this transfer, the heat will remain trapped in the "heat-donor" substance (in this case the hot coffee). Thus, the material chosen (A, B or C) will be the material that resists heat transfer the most based on the explanation above.

Crude oil is derived from which of the following materials?
QveST [7]

I believe that crude oil is derived from plants because it is made up of a liquid that is found beneath the earth surface so I guess you could go with plants it is not an animal or rock or salt so.. could be brainliest not 100% sure so if you are not sure go with your gut
