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>

Ionic crystals are made from ions that are bonded together by ionic bonds. An example is salt crystals that are made of sodium and chloride ions.
Explanation:
An ionic bond is formed when one atom donates electrons to another atom so they both attain stable electron configuration. The two atoms are then bound by their acquired charges. For example sodium atom2.8.1) donates its valence electrons to chlorine atom (2.8.7). They both achieve stable electron configuration of 2.8 and 2.8,8 respectively. Because sodium ion will now have a positive charge (because it has more protons than electrons) and chloride ion will have a negative charge because it has more electrons than protons, the two are bonded together electrostatically forming ionic bonds.
