A mixture of hydrocarbons contains 34.8% heptane, C7H16, 10.1% nonane, C9H20, and 55.1% octane, C8H18. The mixture is combusted in an excess of oxygen. What mass of CO2 is generated from the combustion of 17.0 kg of the mixture?
:

The branch of science which deals with chemicals is called chemistry.

The correct answer is 14.277 kg

The calculation part is as follows:-

Total mass-produced is

Hence, the correct answer is - 14.277kg.

Mass Heptane : 0.348 x 17 = 5.916 kg

mass C in Heptane (MW=100.21 g/mol) :

Mass Nonane : 0.101 x 17 = 1.717 kg

mass C in Nonane (MW=128.2 g/mol) :

Mass Octane : 0.551 x 17 = 9.367 kg

mass C in Otane (MW=114.23 g/mol) :

Total mass produced :

4.959+1.446+7.872=14.277 kg

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
