Answer:
Option (C) 3
Explanation:
The pH scale is a scale that ranges from 0 to 14. The pH reading has various notifications. These notifications are as follow:
1. If the pH reads between 0 and 6, then the solution is acidic.
2. If the pH reads 7, then the solution is neutral.
3. If the pH reads between 8 and 14, then the solution is basic.
With the above information, option C is the correct answer to the question.
Answer:
7
Explanation:
You divide the 14m/s by 2 and get the answer of the acceleration of 7
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:
A flame test is an analytic procedure used in chemistry to detect the presence of certain elements. :)
