Answer:
162.4g of CO2 are produced
Explanation:
The combustion of ethanol, C2H5OH, occurs as follows:
2C2H5OH + 7O2 → 4CO2 + 6H2O
<em>Where 2 moles of C2H5OH produce 4 moles of CO2.</em>
<em />
To solve this question we need to convert the mass of ethanol to moles. Then, the moles of ethanol to moles of CO2 using the balanced reaction and to mass:
<em>Moles C2H5OH -Molar mass: 46.07g/mol-</em>
85.0g * (1mol / 46.07g) = 1.845 moles C2H5OH
<em>Moles CO2:</em>
1.845 moles C2H5OH * (4mol CO2 / 2mol C2H5OH) = 3.69 moles CO2
<em>Mass CO2-Molar mass: 44.01g/mol-:</em>
3.69 moles CO2 * (44.01g/mol) =
<h3>162.4g of CO2 are produced</h3>
Electronegativity is the tendency of atom to attract shared pair of electron towards itself . Its value is out of 4 , and Fluorine is higly electronegative.
So,
D electronegativity, is the correct answer.
Answer:
b
d
a
c
Explanation:
More carbons in longest chain = higher BP
D has a BP of 0.8
A has a BP -0.5
C is the lowest because the more branched it is the lower BP
Answer:
Viscosity of water decreases markedly with increasing temperature. When the viscosity decreases, the flow resistance decreases. So for the same driving force, that is the pressure drop per unit length, the water flow rate will be higher.
Hope this helps :)
Answer:
Lactose, the disaccharide of milk, consists of galactose joined to glucose by a β-1,4-glycosidic linkage. Lactose is hydrolyzed to these monosaccharides by lactase in human beings.
