Explain why powdered magnesium reacts faster with 30cm3 of 2M Hydrochloric acid than equal mass of Magnesium ribbon with 30cm3 of 2M hydrochlorric acid

What does a particular point on a line of a phase diagram represent? o a. the maximum temperature a substance can exist at without bonds breaking b. the pressure created by the kinetic energy of molecules at a particular temperature c. the melting point or boiling point of a substance at a specific pressure d. the conditions in which temperature and pressure have equal effects on a substance

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

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.
