What is the energy released when 0.24kg of methane is completely burnt in oxygen

Meth­ane is a gaseous com­pound with the chem­i­cal for­mu­la of CH₄. Meth­ane has no smell or taste, and is a non-tox­ic sub­stance. The flamma­bil­i­ty lim­it of the gas is a con­cen­tra­tion in air from 5 to 15%.

Meth­ane is the sim­plest rep­re­sen­ta­tive of the alka­nes. This group of or­gan­ic com­pounds is called sat­u­rat­ed or paraf­fin hy­dro­car­bons.

They have a sim­ple bond be­tween the car­bon atoms in the mol­e­cule, and the oth­er va­len­cies of each car­bon atom are sat­u­rat­ed with hy­dro­gen atoms.

The most im­por­tant reaction of alka­nes is com­bus­tion. Alka­nes burn with the for­ma­tion of wa­ter vapor and gaseous car­bon diox­ide. As a re­sult of this re­ac­tion, chem­i­cal en­er­gy is re­leased in huge quan­ti­ties, which can be trans­formed into elec­tri­cal or ther­mal en­er­gy.
