Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . suppose 17. g of octane is mixed with 93.0 g of oxygen. calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. be sure your answer has the correct number of significant digits.

52.8 g of

Explanation:

To calculate the moles, we use the equation:

a) moles of octane

b) moles of oxygen

According to stoichiometry :

2 moles of require 25 moles of

Thus 0.150 moles of   require=  of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

As 2 moles of give =  16 moles of

Thus 0.150 moles of give =  of

Mass of

Thus 52.8 g of will be produced from the given masses of both reactants.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
