How many moles of carbon dioxide are produced from the complete combustion of 5.42 moles of ethanol? 2C2H6O +7 O2 ®4 CO2 + 6H2O

10.84 moles of will be produced from complete combustion of 5.42 moles of ethanol

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

According to stoichiometry :

2 moles of ethanol produce =  4 moles of

Thus 5.42 moles of ethanol will produce=  of  

Thus 10.84 moles of will be produced from complete combustion of 5.42 moles of ethanol

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
