Mouth ⇒ oesophagus ⇒ Stomach ⇒ small intestine ⇒ large intestine ⇒ rectum ⇒ anus.
Note: the liver produces bile which neutralises the acidity of hydrochloric acid in the stomach, but food does not go through the liver. Moreover, the pancreas is a major part in enzyme production, but food does not pass through the pancreas either.
Chemical potential energy
Answer:
The correct answer is D
Explanation:
Many substances hold their molecules together in the liquid or solid bosom. This is due, in addition to the pressure and temperature conditions, by the forces of Van der Waals. These are still produced in nonpolar molecules by the movement of electrons through the molecules; in extremely short periods of time, their electrons "charge" towards one end of the molecule, producing small dipoles and keeping the molecules very close to each other.
<u>Answer:</u> The balanced chemical equation for the combustion of liquid ethanol is written below.
<u>Explanation:</u>
Combustion reactions are defined as the reactions in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water. Heat is released during these reactions.
A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.
The balanced chemical equation for the combustion of liquid ethanol follows:
By Stoichiometry of the reaction:
1 mole of liquid ethanol reacts with 3 moles of oxygen gas to produce 2 moles of carbon dioxide gas and 3 moles of water vapor.
Hence, the balanced chemical equation for the combustion of liquid ethanol is written above.
