cyclohexanol is burned as a fuel, according to the following equation, how many moles of oxygen are needed to produce 13.7 mol o

lidiya [134]

The moles of oxygen that are needed to produce 13.7 moles of carbon dioxide is 21.17 moles of Oxygen

calculation

2 C₆H₁₂O + 17 O₂ → 12 CO₂ +12 H₂O

The moles of O₂ is determined using the mole ratio

that is for given equation above O₂ : Co₂ is 17 :12

therefore the moles of O ₂= 13.7 moles x 17/12 =21.17 moles

Calculate the pOH of a solution if the concentration of hydroxide ions (OH-) is 1.9 x 10-5M?

OLEGan [10]

Answer:

9.28

Explanation:

pOH refers to a measure of hydroxide ions concentration. pOH tells about the alkalinity of a solution. If pOH is less than 7 then aqueous solutions are alkaline, acidic if pOH is greater than 7 and neutral if pOH is equal to 7.

Concentration of the hydroxide ions = 1.9 x 10-5 M

pH = $-log(1.9\times 10^{-5})=4.72$

pOH = 14 - pH

=14 - 4.72 = 9.28
