Write out these balanced equations (include physical states): Solid iron(II) hydroxide decomposes to form solid iron(II) oxide and liquid water.   Solutions of silver nitrate and aluminum iodide are mixed together, forming solid silver iodide and aqueous aluminum nitrate.   When calcium metal is placed in water, hydrogen gas bubbles out, leaving a highly alkaline (basic) solution. Write the balanced chemical equation for this reaction. Phases are optional. Do not write an ionic equation (i.e., the answer should not show any charges).
