We are given the chemical reaction and the amount of fuel used for the process. We use these data together with the molar masses to obtain what is asked. We do as as follows:
100 g C8H18 ( 1 / 114.33) ( 16 / 2 ) = 6.9973 mol CO2 produced
Answer:
<h2>87.21 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>87.21 moles</h3>
Hope this helps you
Explanation:
An atom consists of electrons, protons, and neutron. The protons and neutrons are present inside the nucleus whereas the electrons are present outside the nucleus.
These electrons revolve around the nucleus in circular motion. Therefore, an electron pair surrounds the central atom of a molecule. It is known that an electron contains a negative charge and like charges repel each other.
Hence, in an atom the force of repulsion between electron pairs pulls the atoms away from each other.
As a result, a molecules atoms are as far away from each other as they can get.
Answer:
CO(g) + H₂O(g) <=> CO₂(g) + H₂(g), (volume is decreased) .. No effect.
PCl₃(g) + Cl₂(g) <=> PCl₅(g)
, (volume is increased) .. Shift left.
CaCO₃(s) <=> CaO(s) + CO₂(g)
, (volume is increased) .. Shift right.
Explanation:
<em>Le Châtelier's principle</em><em> states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>

<em>CO(g) + H₂O(g) <=> CO₂(g) + H₂(g) (volume is decreased)</em>
- When volume is decreased, the pressure will increase:
- When there is an increase in pressure, the equilibrium will shift towards the side with fewer moles of gas of the reaction. And when there is a decrease in pressure, the equilibrium will shift towards the side with more moles of gas of the reaction.
- The reactants side (left) has 2.0 moles of gases and the products side (right) has 2.0 moles of gases.
So, decreasing the volume will have no effect on the reaction.
<em>PCl₃(g) + Cl₂(g) <=> PCl₅(g)
, (volume is increased)</em>
- When volume is increased, the pressure will decrease:
- When there is an decrease in pressure, the equilibrium will shift towards the side with more moles of gas of the reaction.
- The reactants side (left) has 2.0 moles of gases and the products side (right) has 1.0 mole of gases.
- So, decreasing the pressure will shift the reaction to the side with more moles of gas (left side).
so, increasing the volume will shift the reaction left.
<em>CaCO₃(s) <=> CaO(s) + CO₂(g)
, (volume is increased)</em>
- When volume is increased, the pressure will decrease:
- When there is an decrease in pressure, the equilibrium will shift towards the side with more moles of gas of the reaction.
- The reactants side (left) has 0 moles of gases and the products side (right) has 1.0 mole of gases.
- So, decreasing the pressure will shift the reaction to the side with more moles of gas (right side).
so, increasing the volume will shift the reaction right.
