Answer:
It is a mixture that is uniform in both composition and properties.

Answer:
The solution in the buret, during a titration is called titrant.
Explanation:
A titration is a useful process, that makes you know the concentration of a solution. A titrant solution (burette) is evaluated against a titrand to control the pH changes against the volume aggregate. Only a strong acid with a strong base, a strong base with a strong acid, a weak acid with a strong base and a weak base with strong acid are valued.
When the pH reaches the equivalence point, it is said that the normality of the acid by the milliequivalents, is equal to the basic normality by its milliequivalents. In conclusion, the entire base / acid became its conjugate pair.
To check this sudden change in pH, a substance is used, called Indicator that changes the color of the titrand (analyte).
In a titration analysis, the substance in the buret is called the 'titrant'. It is used to react with the analyte, the sample solution whose concentration we're measuring. The goal is to reach the endpoint, the point when a distinct visual change indicates that the titrant has completely reacted with the analyte.
In a titration analysis, the solution in the buret is called the titrant. This solution contains a known concentration of a substance. During a titration, this titrant is added incrementally to a sample solution, called the analyte, which contains the substance whose concentration is to be measured. The titrant and analyte undergo a chemical reaction of known stoichiometry.
By measuring the volume of the titrant solution needed to completely react with the analyte, scientists can calculate the concentration of the analyte. This point where the titrant has completely reacted with the analyte is termed the equivalence point of the titration. The process of adding the titrant is halted when a distinct change is visually detected in the solution - this could be a color change, for example. This is known as the end point.

Carbon
Nitrogen
Answer: True
Air is a mixture of many things; it's not just Oxygen, but Hydrogen, Carbon, and Nitrogen as well are made up of air. Fun fact: Nitrogen is actually more abundant in air
Answer: B. Ca(OH)2
Explanation:just took the quiz/quick check
The Precision of a calculated answer is limited by the least precise measurement used in the calculation is false.
If the average value of different measurements is similar to the correct value of the measurement is said to be accurate and if the value of different measurements is close to each other then it is said to be precise.
The everage value of the different measurements may or not may be the same as exact and the resultant values must be the same as the calculated value for the precision of the result.
Therefore, the Precision of a calculated answer is limited by the least precise measurement used in the calculation is false.
