The statement best describes the difference between a substance with a pH of 3.0 and a substance with a pH of 6.0 is - The substance with the lower pH has 1,000 times as many hydrogen ions per volume of water.
pH is the scale or measure for the substance about its acidic or basic strength. It ranges from 0 to 6.9 which is acidic and 7.1 to 14 which is basic.
Acidic substance has high concentration of Hydrogen ions whereas, basic substance has low concentration of hydrogen ions, however for the OH⁻ ions it is reverse.
- Concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log() then,
=> 3 = -log ()
=> = (for pH = 3)
=> pH = -log()
=> 6 = -log ()
=> =
(for pH = 6)
Thus, The substance with the lower pH (3) has 1000 times as many hydrogen ions per volume of water.

A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density of a 240-g rock that displaces 89.0 cm³?
Answer:
Explanation:
Given data
Mass m=240g
Volume V=89.0 cm³
To find
Density d
Solution
If rock displaces 89.0 cm³ of water means volume of rock is also 89cm³
So
Answer:

The magnetic field along z axis is
Explanation:
Given that,
Length of the current element
Current in y direction = 5.40 A
Point P located at
The distance is
We need to calculate the magnetic field
Using Biot-savart law
Put the value into the formula
We need to calculate the value of
Put the value into the formula of magnetic field
