Explain an acidic solution of permanganate ion reacts with oxalate ion to form carbon dioxide also Mn. State the balanced equation for the reaction.
What's the central atom for NaOH, how many bonds are formed, is it polar or nonpolar, and what's the direction of electronegativity
The specific heat of an unknown metal is found to be 0.233 J/K g. The Law of Dulong and Petit predicts a molar heat capacity of 26 J/K mol. Use this law to estimate the molar mass of the metal.
Consider a solution of carbonic acid, H2CO3. (a) Calculate the H3O+ ion concentration of a 0.15 M solution of carbonic acid.
