Answer: 0.5 hour / 30 minutes / 1800s

Explanation: The problem can be expressed through the following equation:

v = d/t

Derive to find t:

t = d/ v

= 300 km /600 km/ h

= 0.5 hr

0.5 hr x 60 mins/ 1 hr = 30 mins

Or in seconds

30 mins x 60 s/ 1 min = 1800 s

Answer:

30 minutes

Explanation:

If the plane is going 600 km/h

divide the length and time and it would be half of that, so 300 km would take 30 mins.

5. Some areas of the nation have limestone in the soil and lake bottoms. Explain how the presence of this mineral acts as a natu
mixer [17]

Limestone is calcium carbonate Ca(Co3) it's dissociation equation is as follows: Ca(CO3) <----> Ca+2 + CO3-2 

but the solubility is very small in the presence of acid by LeChatlier's Principle you can shift to the right by adding acid 

H+ + CO3-2 <-----> H+CO3- (the bicarbonate ion which is really soluble) 

The system will pull more and more limestone out into solution as acid is added and neutralize the acid coming from the rain.

What is the similarity between simple diffusion and facilitated diffusion?
MakcuM [25]

they are both types of passive transport which means they require no energy. They both work with the concentration gradient which means they go from a high concentration area to a low concentration area. The differences are simple diffusion just goes though the membrane of a cell while facilitated diffusion uses a protein channel

Simple diffusion: it is the process where molecules move from a area of high concentration to an are of lower concentration. There is no energy needed in simple diffusion. For example when sodium is highly concentration in a cell, it moves outside of the cell where sodium is less concentration. it takes no energy as simple diffusion is random and molecules move according to their concentration.

Choose the options below that are true.
Assoli18 [71]

Answer:

The options <u>(A) -</u>The rate law for a given reaction can be determined from a knowledge of the rate-determining step in that reaction's mechanism.  and <u>(C) </u>-The rate laws of bimolecular elementary reactions are second order overall ,<u>is true.</u>

Explanation:

(A) -The rate law can only be calculated from the reaction's slowest or rate-determining phase, according to the first sentence.

(B) -The second statement is not entirely right, since we cannot evaluate an accurate rate law by simply looking at the net equation. It must be decided by experimentation.

(C) -Since there are two reactants, the third statement is correct: most bimolecular reactions are second order overall.

(D)-The fourth argument is incorrect. We must track the rates of and elementary phase that is following the reaction in order to determine the rate.

<u>Therefore , the first and third statement is true.</u>
