Calculate the EMF of the following concentration cell: (also explain each step of calculation) Mg(s) | Mg2+ (0.2 M) || Mg2+ (0.6 M) | Mg(s)

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.
