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>
835 g Ar to liters of Argon gas is calculated as follows
find the moles of Ar = mass/molar mass
= 835g /39.95 g/mol = 20.9 moles
At STP 1mole of ideal gas = 22.4 L, what about 20.9 moles
= 20.9 moles/1mole x 22.4 L =468.16 L of Argon
The answer is glass is the easiest to recycle
