Question

Write a balanced chemical equation when (iii) Manganese dioxide is heated with aluminum powder.

Answer 1

Chemical reactions:

• The process of two or more molecules interacting to create a new product is known as a chemical reaction.
• Reactants are substances that interact to make new substances, whereas products are those substances that result from the interaction.

Aluminium powder is used to heat manganese dioxide.

• Magnesium oxide is the chemical formula for manganese dioxide.
• Aluminium powder is represented chemically as $\mathrm{Al}$.
• Let's look at the balanced chemical equation for the reaction at hand.
• $$\begin{gathered} 3{\mathrm{MnO}}_2\left(\mathrm{s}\right)+4\mathrm{Al}\left(\mathrm{s}\right)\to 3\mathrm{Mn}\left(\mathrm{s}\right)+2{\mathrm{Al}}_2{\mathrm{O}}_3\left(\mathrm{aq}\right) \\ \mathrm{Manganese}\mathrm{Aluminium}\mathrm{Manganese}\mathrm{Aluminium} \\ \mathrm{Dioxide}\mathrm{Oxide} \end{gathered}$$.
