Question

Using chemical symbols write and balance the molecular equations in standard form (lowest integers). Include phases for all equations. You may have to decide on the products. You can use the formula editing tool to help you or, for example, enter H2O for H2O. Use "->" for the → symbol. Be sure to leave a space before plus signs and arrows.
Part 1

An aqueous solution of copper(II) nitrate is added to an aqueous solution of sodium hydroxide (decide on the products).

Part 2

Solid iron(III) oxide and aluminum metal react to form iron metal and solid aluminum oxide.

Answer 1

This is the best I can do using the equation tool,
\[CuNO_{3}(aq) + 2NaOH(aq) \rightarrow Cu(OH)_{2} (s) + Na_{2}NO_{3}(aq)\]
Cu(NO3)2 (aq) + 2NaOH (aq) → Cu(OH)2 (s) + Na2NO3 (aq)

\[Fe_{2}O_{3} (s) + 2Al(s) \rightarrow 2Fe(s) + Al_{2}O_{3}(s)\]
