Question

A small quantity of copper (II) carbonate is heated in hard glass test tube. i. Record your observation. ii. Give the equation for the same. iii. Which type of change is this. Give reason.

Answer 1

Answer:

this is your answer this is your answer

Answer 2

Answer:

the reaction is balanced with respect to mass and , as indeed it must be if it reflects chemically reality. Most carbonates undergo this decomposition, provided your supply enuff heat to the reaction

Typically, we would fiercely heat the copper carbonates in a vessel whose out flow we bled into a solution of limewater, Ca(OH)² (aq). The librated carbon dioxide would react with the calcium hydroxide to form a carbonate

Ca(OH)² +( aq) + carbon dioxide (g) --- Ca Co³ (s)

+ H² o
