The initial number of moles of the unknown acid (HA) is equal to the final amount of the number of moles of the known base (NaOH) because they fully consumed each other.
<h3>What is neutralization reaction?</h3>
Neutralization reactions are those reactions in which acids and bases reacts with each other for the formation of water and salt.
Acids reacts with base to form salt means all gets consumed by each other so the initial moles of an unknown acid is equal to the final moles of the known base.
And reaction between them is shown as:
HA + NaOH → NaA + H₂O
Hence acids and bases fully consumed each other that's why we can calculate the moles of unknown substance.

The correct option is C.
Finance charge on credit card refers to the interest you pay for borrowing money when you are using a credit card. It is the interest you are charged on the debts you owe and sometimes it might include other charges such as penalty fees for late payment. Individual finance charge is usually calculated using the the person APR [Annual Percentage Rate], amount of debt owe and the time period been considered. The higher your debts, the higher your finance charge.
Answer:
The Following are the matching to this question:
Explanation:
- It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.
- Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.
- Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.
- The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.
- The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
- It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.
