Oxygen gas generated in an experiment is collected at 25°C in a bottle inverted in a trough of water. The external laboratory pressure is 1.000 atm. When the water level in the originally full bottle has fallen to the level in the trough, the volume of collected gas is 1750 ml.
The feature of waves that you are noticing is called the amplitude. That's the height of the wave from the average water level to the crest, or, conversely, the depth down to the trough. In the macroscopic world, the amplitude of the waves is really important.
Oct 18, 2024 · Successive ionisation energies of an element. The successive ionisation energies of an element increase. This is because once you have removed the outer electron from an atom, you have formed a positive ion. Removing an electron from a positive ion is more difficult than from a neutral atom.
Ionisation energy. The first ionisation energy is the energy involved in removing one mole of electrons from one mole of atoms in the gaseous state. The first...
Chemical reactions vary in speed. The rate of reaction measures how much product is made in a given time. For reactions to occur, reactant particles must collide. Part of...
Investigate the effects of changing the conditions of a reaction on the rates of chemical reactions by measuring the production of a gas (in the reaction between hydrochloric acid and marble chips).

Among the effects that this model describes are the increasing spacing between peaks (or troughs) in the periodic signal of anode current vs. acceleration voltage, the effect of temperature on the peak spacing in the Hg experiment, and an explanation of why the peak spacing is typically wider than the energy of the first (lowest) excited state o...
