sodium metal vs vinegar experiment @MR. INDIAN HACKER #shorts #e_bull_jet #ytshorts #shortsindia

One day Vabhav was performing experiments in the science laboratory based on the of chemical combination. Just then his chemistry teacher, Mr. Rajeev, came into the laboratory. Mr. Rajeev told Vaibhav that in an experiment conducted byby a class IX student when 10.6 g of sodium carbonate was reacted with 12.0g of ethanoic acid in a closed flask, then 16.4 g of sodium ethanoate, 4.4 g of carbon dioxide and an unknown mass of substances Y were produced. Mr. Rajeev asked Vaibhav to make use of this information and answer the following questions : (a) Write a word equation for the reaction which takes place on reacting sodium carbonate and ethanoic acid (b) Which is the substance Y which is produced in this reaction ? (c) What mass of substance Y is produced in this reaction ? (d) Which law of chemical combination has been made use of in calculating the mass of substance Y ? State this law (e) What values are displayed by Vaibhav in this eposide ?

In an experiment 50ml of 0.1(M) solution of a salt is reacted with 25ml of 0.1(M) solution of sodium sulphite. The half equation for the oxidation of sulphite ion is SO_(3)^(2-)(aq)+H_(2)O rarr SO_(4)^(2-)(aq)+2H^(+)(aq)+2e^(-) If the oxidation number of metal in the salt was 3 , what would be the new oxidation number of metal?
