Write a balanced half-reaction for the reduction of aqueous hydrogen peroxide to liquid water in basic aqueous solution. Be sure to add physical state symbols where appropriate.

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Which of these is not an example of chemical weathering? a. iron-rich mineral rusting b. feldspar turning into clay c. limestone reacting with acid d. granite breaking up into sand

Achemical reaction is done in the setup shown, resulting in a change of mass. what will happen if the same reaction is done in a sealed container that is placed on the electronic balance?
