you can tell a triple-beam balance is level when the
a. three beams are all lined up
b. balance tips back to the right
c. object does not slide off the pan
d. pointer lines up with the white line labeled 0

C. object does not slide off the pan

Explanation:

Triple beam balance is the name given to an instrument that is capable of measuring the mass of objects and measuring substances. This instrument is composed of three bundles, as the name says, the front bundle, the middle bundle and the long bundle. These three beams together indicate the difference in people and measurements of the objects in individual analyzes. When the balance of the triple beam is level you will notice that the measured object will not slide out of the pan

an acid is any substance that has pH of less than 7. The pH scale is used to measure how acid or alkali a substance is:

Explanation:

0-3 = strong acid (UI turns red)

4-6 = weak acid (UI turns orange/yellow)

7 = neutral (UI turns green)

8-10 = weak alkali (UI turns blue)

11-14 = strong alkali (UI turns purple)

The pH of an acid is determined by the concentration of Hydrogen ions (H+) the substance has when in solution. All acids contain hydrogen ions when in solution; the higher the concentration of H+ ions, the lower the pH.

Fast Fact: Bee stings are acidic. They can be neutralized using baking powder which contains sodium hydrogen carbonate.
