Easy

Magnesium oxide reacts with dilute nitric acid to form magnesium nitrate and water.

The equation for the reaction is:

MgO(s)+2HNO3(aq)→Mg(NO3)2(aq)+H2O(l) \text{MgO}(\text{s}) + 2\text{HNO}_3(\text{aq}) \rightarrow \text{Mg(NO}_3)_2(\text{aq}) + \text{H}_2\text{O}(\text{l}) MgO(s)+2HNO3​(aq)→Mg(NO3​)2​(aq)+H2​O(l)

Which of the following correctly identifies the physical state of each substance in the chemical equation?

magnesium oxide: solid | nitric acid: aqueous | magnesium nitrate: aqueous | water: liquid

magnesium oxide: solid | nitric acid: liquid | magnesium nitrate: solid | water: aqueous

magnesium oxide: aqueous | nitric acid: aqueous | magnesium nitrate: solid | water: liquid

magnesium oxide: aqueous | nitric acid: liquid | magnesium nitrate: aqueous | water: aqueous
