Answer:
B. Measures of central tendency
Explanation:
Mean, median and mode are best described as measures of central tendency of a given data set.
Mean is the average of the samples given
Mode is the data point with the most frequent occurrence
Median is the data point that lies in the middle
- All these parameters tells us how far a data point is from the middle or how close they are.
The balanced chemical equation in a basic solution will be,
→
The reaction in which oxidation and reduction reaction takes place simultaneously is called redox reaction or oxidation - reduction reaction .
Rules for the balanced chemical equation in a basic solution are :
- First write half - reaction.
- Now balancing the main atoms in the reaction
- Now balancing the hydrogen and oxygen atoms on both sides of the reaction .
- If the oxygen atoms is not balance on both side then add water molecule at that side at that side where more number of oxygen atom is present.
- If the hydrogen atom are not balanced on both side then add hydroxide ion at that side of where less number of hydrogen are present.
- Now at last balance the charge.
Therefore, the balanced chemical equation in a basic solution will be,
→
