H+ conc = antilog to negative pH
H+ conc of pH 3 = 1 x 10^-3 M
One unit pH change of the H+ concentration is by a factor of 10. Since pH 3 to pH 5 is 2 unit changes, pH 3 then has one hundred<span> times more H+ concentration than a pH of pH 5. </span>
Answer:
X>5
Explanation:
4x-20> 5-x
1) add x on both sides
2) you should then have 5x-20> 5
3) add 20 on each side
4) you should then have 5x>25
5) divide each side by 5
6) your answer is x>5
Answer:
B They are most often young males who are poor, homeless, and sickly.
Solution :
Simplifying the left side of the equation
Transposing 6 to the other side
Subtracting to get the final no.
Cross multiplying we get
Dividing it
<u>Henceforth, the solution of this eq. is 7</u>
