1 day ago · Ionization chart across the period. Specifically for example in Period 2 of the periodic table, the ionization chart shows that the first ionization energy increases from lithium (Li) to neon (Ne). Lithium has a low ionization energy because it has a relatively small effective nuclear charge and a larger atomic radius.
5 days ago · Answer. There are three ions in this equation: magnesium ions, copper ions, and sulfate ions. The spectator ion is the ion that remains unchanged during the reaction. We can write the ionic equation for this reaction as follows: M g () + C u () + S O () M g () + S O () + C u () s a q a q a q a q s 2 + 4 2 – 2 + 4 2 –.
Answer. An acid, as defined by Brønsted and Lowry, is a substance that can lose or donate a proton ( H +) in a reaction. The nitric acid can donate a proton to become a nitrate ion ( N O 3 – ). As the acid is in solution, the water molecules can accept the proton to become hydronium ions ( H O 3 + ):
5 days ago · Definition: Irreversible Reaction. An irreversible reaction is a reaction that proceeds in one direction only; the products do not react together to reform the reactants. An example of this is when the fuel in a Bunsen burner undergoes combustion. The fuel is often a mixture of propane and butane.
Apr 20, 2024 · Now , we define the isotonic solutions as two solutions which have the same osmotic pressures, and also , there will be no movement of solvent if they are kept side by side separated by a selectively permeable membrane. Now if we have two solutions, each of two different solvent , say A and B , but have the same osmotic pressures, i.e.
Apr 26, 2024 · Its chemistry is expected to be similar to other actinides, with a few notable predictions: Oxidation States: Lawrencium predominantly exhibits a +3 oxidation state, similar to other late actinides. The presence of a 7p electron suggests a possible +1 oxidation state, but this is less stable and not commonly observed. Halides Formation:
Apr 22, 2024 · State the unit of strength in chemistry. The mass of solute (in grammes) dissolved in one litre of solution is the strength of the solution. The strength units are gL–1 or g dm–3.
