2. ask a question
3. form a hypothesis
4. test the hypothesis
5. analyze results
5 , drawing conclusions,
6. and communicating the results
Explanations:
<u>Question</u> <u>1:</u> Lithium in 20.00+ g is C. or D., but 25.00+ g is D. which means this is the correct option.
I am unsure of <u>Question</u> <u>2</u>. I don't think it is mole though.
<u>Question</u> <u>3:</u> Boron in 25.00-30.00 g is B. or D., but 25.00 g would be C.
<u>Question</u> <u>4:</u> 2.393 x 1024 atoms of Oxygen is 63.58 mole O. I don't know for sure, but I think this is correct.

The volume of the base should be gradually increased, stopping once the equivalence point is achieved. At the volume halfway between the equivalence point and the acid, the acid's pKa is equal to the pH.
<h3>What is titration, for instance?</h3>
Titration, sometimes referred to as titrimetry, is a method for calculating the concentration of a specific analyte in a mixture that is used in chemical qualitative analysis. Titration, which is also sometimes referred to as volumetric analysis, is a crucial analytical chemistry method.
<h3>What governs titration in its basic form?</h3>
The following is the fundamental titration principle: The sample being studied is given a solution, referred to as a titrant or standard solution. A chemical is present in the titrant in a known concentration.
