Hello!
Fossil fuels are Carbon-based compounds that when heated in the presence of oxygen undergo a combustion reaction to produce thermal energy and gases. The chemical equation for the combustion of a generic Fossil Fuel (C) is the following:
C + O₂ →CO₂
From this chemical reaction, we can see that CO₂ (Carbon Dioxide) is produced, so the consumption of fossil fuels has increased the Carbon Dioxide concentrations in the atmosphere.
Have a nice day!

The concentration of HCONH2 in equilibrium is 0.55M
Explanation:
Gasoline is a mixture of compounds called hydrocarbons (compounds of hydrogen and carbon). It is obtained by purifying crude oil by fractional distillation. Gasoline is most commonly referred to as a mixture of compounds, therefore it is a mixture. Gasoline is composed of hydrocarbons combined with different concentrations of ethanol. <span>Pure substances can be either elements or compounds. </span>Mixtures<span> can be either</span>homogeneous or heterogeneous<span>. Another term for a </span>homogeneous mixture<span> is a solution. ... </span>Gasoline<span> is thus a blend of different compounds, so it is a </span>mixture<span>.</span>
