If 3 mol of [tex]$H_2O_2$[/tex] is decomposed according to the equation [tex]$2H_2O_2 \rightarrow 2H_2O + O_2$[/tex], but only 38.6 g of [tex]$O_2$[/tex] is collected, what is the percent yield of [tex]$O_2$[/tex]?

Answer :

Changes in energy as well as changes in matter are part of chemical reactions, such as those that take place when you light a match.

Thus, Without the energy provided by chemical processes, societies at all developmental levels would be unable to function. About 85% of the energy used in the US in 2012 comes from burning coal, wood, trash, and petroleum products.

We use this energy to generate electricity (38%), move people, products, and food (27%), produce industrial items (21%), and heat and power our homes and companies (10%) and chemical reactions.

While these combustion reactions aid in meeting our basic energy demands, the majority of scientists agree that they also play a significant role in the development of global warming.

Thus, Changes in energy as well as changes in matter are part of chemical reactions, such as those that take place when you light a match.
