Answer to Question #201307 in General Chemistry for Hlasoa

Question

An analysis of seven aspirins tablets from a population known to have a standard deviation of 5,gives the following results in my aspirins per tablet:

246, 249, 255, 251, 251, 247, 250

What is the 95% confidence interval for the population's expected mean?

Answer 1

The oxidation number of copper in reactant half cell is 0 but the oxidation number of copper in product half cell is 2. As there is an increase in the oxidation number of copper so copper is being oxidized.

The oxidation number of Silver in reactant half cell is +1 but the oxidation number of Silver in product half cell is 0. As there is an decrease in the oxidation number of Silver so silver is being reduced.

Oxidizing agents are the substance which oxidize other substance and get reduced themselves so silver is oxidizing agent here.

Reducing agents are the substance which reduce other substance and get oxidized themselves so copper is reducing agent here.
