Answer:
the left one
Explanation:
heavier means it goes faster
Answer:
Explanation:
From the given information:
At wavelength = 270 nm

At 270 nm
Suppose x is said to be the solution for the concentration of x and y to be the solution for the concentration of y;
Then:


Divide both sides by 200


Use l = 1cm (i.e the standard length)
Then;

<u>For 540 nm:</u>


since l = 1

Equating both (1) and (2) together, we have:

Hi my dear friend,
Because we must add heat, boiling water is a process that chemists call endothermic. Clearly, if some processes require heat, others must give off heat when they take place. ... Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing.
