Gasohol is a mixture of ethanol and gasoline. balance the equation and determine the mass of co2 produced from the combination of 10.00g of ethanol C2H5OH(l) + 3 O2(g) -> 2 CO2(g) + 3 H2O(g)

(10×2×44)÷46

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.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
