A metal is thought to be copper or aluminium. When 6.5 g of the metal absorbs 12 J, its temperature rises by 4.8 °C. Identify the metal and give reason for your answer

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. the values of phosphorous acid are 1.30 6.70 calculate the ph for each of the given points in the titration of 50.0 ml of 1.5 m h3po3(aq) with 1.5 m koh(aq) .

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.
