Question

How do you indicate a gas in a balanced chemical equation?

Answer 1

Balance chemical equation -

• The same number of atoms of different elements on the reactants and products side is called the balanced chemical equation.
• This is done by the hit and trial method using coefficient and multiples till the number is obtained.
• The triangle on the arrow$\stackrel{∆}{\to }$ shows the heating condition.
• Upward arrow (⤒) indicate the gaseous product in the chemical equation.

Example - ${\mathrm{CaCO}}_3\stackrel{∆}{\left(\mathrm{s}\right)\to }\mathrm{CaO}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)\uparrow$
