It depends on which manner the formulae is being asked but the answer is: KNO3
The correct answer is: by the transfer of one or more electrons from one atom to another.
It is the answer of 10 51
These are the factor that you observe or measure.
Percent yield is 23.11 % when 162.8 g of CO2 are formed from the reaction of excess amount of C8H18 and with 218.0 grams of O2.
Explanation:
Balanced equation for the chemical reaction:
2C8H18 + 25O2 → 16CO2 + 18H2O
data given:
CO2 formed (actual yield) = 162.8 grams
mass of oxygen = 218 grams
16 moles of CO2 formed when 5 moles of oxygen reacted
3.6 moles of CO2 formed when 6.8 moles of oxygen reacted.
In the reaction 16 moles of CO2 will have 44.01 x 16
theoretical yield of CO2 = 704.16 grams
percent yield =
x100
putting the values in the above equation
percent yield =
x 100
= 0.23 x 100
= 23.11 %
Percent yield is 23.11 %.
