A mixture of methane $\left(\mathrm{CH}_{4}\right)$ and ethane $\left(\mathrm{C}_{2} \mathrm{H}_{6}\right)$ of mass $13.43 \mathrm{g}$ is completely burned in oxygen. If the total mass of $\mathrm{CO}_{2}$ and $\mathrm{H}_{2} \mathrm{O}$ produced is $64.84 \mathrm{g}$ calculate the fraction of $\mathrm{CH}_{4}$ in the mixture.

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Chemical reactions can be either spontaneous, requiring no input of energy, or non-spontaneous, typically following the input of some type of energy, such as heat, light or electricity. Chemical reactions are usually characterized by a chemical change, and they yield one or more products after the reaction is complete. Chemical reactions are described with chemical equations, which symbolically present the starting materials, end products, and sometimes intermediate products and reaction conditions. Chemical reactions happen at a characteristic reaction rate at a given temperature and chemical concentration. Typically, reaction rates increase with increasing temperature because there is more thermal energy available to reach the activation energy necessary for breaking bonds between atoms.

Let the amount of methaneb is equal to x g m. Thus, the amount of thine is equal to 13.43 minus x g m and balance reaction. Formata. We have 2 mole of c 22 mole of c h, 4 methane, plus 2 mole of oxygen and c o 2 plus h, 2 o. This is a reaction 1 and next is balance reaction for athene an then we have 2 moles of athene c 2 s. 6 plus 7 oxygen and 4 mole of c o 2 plus 6 molo h 2 on this is reaction to from reaction 1. We see that 1 mole of c h. 4 produces 1 mole of c 2, scwofom c h. 4 is equal to 44, divided by 16 into x, is equal to 2.744 multiply g m of c o 2 and astro form form from c h. 4 is equal to 18 divided by 16 into 2 by 1 into x is equal to 2.247. Multiply g m h, 2 o. Similarly, from reaction to 2, moles of ethane produces 4 moles of co. 2. So c, o 2 from ethane is equal to 44, divided by 13 into 4, divided by 2 into 13 point. Fourty 3 minus x is equal to 2.927 into 13.43 minus x g m c, o 2 h 2 from 18 c 286 is equal to 18 divided by 30 into 6, divided by 2 into charge, .43 minus x is equal to 1.798 into 13.43 minus x g M h, 2 o, given that the total ofthe total mass of c o 2 h 2 o produced is 64.842 .744 x plus 2.247 x plus 2.927 into 13.43 minus x, plus 1.78798 into 13.43 minus x is equal to 64.84 on solving the above region, 11 unknown Problem we get x x is equal to 5.2 g m. The friction of methane ch 4 in the mixture is 5.2 over 13.43 is equal to 0.387. Is the fraction of ch 4 in the mixture.
