Food or liquid that is consumed by the body eventually gets digested and then eliminated as waste. This process ensures that the body gets rid of what it no longer needs or can't use.

What requirements must be satisfied for a reaction to be feasible for titration?

For a reaction to be feasible for titration, it must be a quantitative reaction, meaning it goes to completion with a known stoichiometry. The reaction must also be fast enough to proceed to completion within a reasonable time frame. Additionally, the reaction should have a distinct endpoint to indicate completion.


What phase change is taking place when a substance goes from a gas to a liquid?

The phase change when a substance goes from a gas to a liquid is called condensation. This occurs when the temperature of the gas decreases, causing the gas particles to lose energy and come together to form a liquid.


Why do reactants in a chemical reaction weigh exactly the same as different products at the end of a reaction?

Energy may only be transformed from one sort to another. Mass is a form of Energy and as such, must be, and is, conserved. It is 'of no surprise' then, that the number of atoms that enter a chemical reaction is equal to the number of atoms that exist after the reaction has been completed.


What things must happen in order that a substance can be smelled?

For a human to smell a substance, The substance must be volatile, and molecules of it must be airborne and drift near the nose. The substance must come in contact with an olfactory nerve-ending in the nose. The olfactory nerve must react, by excitation, to the molecule, sending an electrical impulse to the brain. The brain must receive and process olfactory (smell) nerve signals.


What must be done to make oxygen a liquid?

To make oxygen a liquid, it must be cooled to a temperature below its critical temperature of -118.57 degrees Celsius and be subjected to high pressure. This will cause the oxygen molecules to come close together and transition from a gas to a liquid state.
