Answer:
Kinetic energy is motion; it is the motion of waves, electrons, atoms, molecules, substances, and objects. Electrical energy is the movement of electrons.

<span>Co3+ is Cobalt with three electrons removed (It's positive by 3). So, the abbreviated notation for Cobalt, minus three electrons (Coming from 4s and 3d) is:
[Ar]4s1, 3d5</span>
When a weak acid is titrated against a strong base, the pH of the solution rises, levels off through the buffer zone, and then rises quickly to reach the equivalence point.
<h3>What is titration?</h3>
Titration is a typical research center technique for quantitative investigation synthetic to decide the convergence of a recognized analyte. Titration is a crucial cycle in the creation of cheddar. For this situation, titration is significant while estimating the pH and acridity of the underlying milk being utilized to make the cheddar. Corrosive base titration is a quantitative investigation of convergence of an obscure corrosive or base arrangement. Titration, otherwise called titrimetry, is a typical lab strategy for quantitative substance investigation that is utilized to decide the convergence of a distinguished analyte. A reagent, called the titrant or titrator is ready as a standard arrangement. A known fixation and volume of titrant responds with an answer of analyte or titrand to decide focus. The volume of titrant responded is called titration volume.

Answer:
The equilibrium vapour pressure of a liquid is the pressure exerted by a vapour in a closed vapour and gas system which is in thermal equilibrium.
It is measured using a simple manometer
Explanation:
When liquid and vapour are in a closed container, the molecules of the liquid and vapour at a certain temperature, will attain thermal equilibrium. this means that there is no net transfer of heat between the bodies. The pressure exerted by the vapour on the liquid at this point is called the equilibrium vapour pressure.
To measure the equilibrium vapour pressure, the instrument used is a manometer. To use this, a sample of the liquid is dropped in a sealed flask connected to a manometer, and the increase in the pressure of the system is monitored as the fluid evaporates. This increase in pressure is known as the vapour pressure.
