Does the production of a new gas by a substance represent a chemical property? explain.

Explanation:

Property of a substance which makes chemical changes in the composition of  any substance is known as chemical property.

Evolution of gas also represents that a chemical change has taken place in the chemical reaction and therefore it brings chemical change in composition of substances.

For example, when sodium carbonate reacts with hydrochloric acid then it results in the formation of carbon dioxide gas and water.

This reaction shows that chemical composition of reactants has changed and thus, it is a chemical reaction.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
