Interpretation:
Chemical equation for the decomposition of aluminum oxide needs to be determined.
Concept introduction:
In a
A chemical equation is balanced by balancing the number of moles of each element on the reactants and on the products.
Answer to Problem 18PP
Chemical equation of the given decomposition reaction is as follows:
Explanation of Solution
Chemical equation of the reaction is as follows:
The above equation can be balanced by giving coefficients 2, 4 and 3 to
Thus, the balanced chemical equation will be:
Aluminium oxide decomposes when electricity passes through it to generate solid aluminium and oxygen gas.
This reaction is a decomposition type reaction. It is because in a decomposition reaction, a compounds breaks down to generate two or more than two new compounds or elements.
Chemical equation of the decomposition reaction,
“Aluminium oxide (s) decomposes when electricity passes through it” is,
In this reaction, aluminium decomposes on passing electricity to produce aluminium and oxygen.
