Outline the steps needed to determine the limiting reactant when 0.50 mol of Cr and 0.75 mol of H3PO4 react according to the following chemical equation.\(2Cr + 2{H_3}P{O_4} \to 2CrP{O_4} + 3{H_2}\). Determine the limiting reactant.
Use the following equations to answer the next four questions:
i.\({H_2}O\left( s \right) \to {H_2}O\left( l \right)\)
ii.\(N{a^ + }\left( {aq} \right) + C{l^ - }\left( {aq} \right) + A{g^ + }\left( {aq} \right) + NO_3^ - \left( {aq} \right) \to AgCl\left( s \right) + N{a^ + }\left( {aq} \right) + NO_3^ - \left( {aq} \right)\)
iii.\(C{H_3}OH\left( g \right) + {O_2}\left( g \right) \to C{O_2}\left( g \right) + {H_2}O\left( g \right)\)
iv. \(2{H_2}O\left( l \right) \to 2{H_2}\left( g \right) + {O_2}\left( g \right)\)
v. \({H^ + }\left( {aq} \right) + O{H^ - }\left( {aq} \right) \to {H_2}O\left( l \right)\)
(a) Which equation describes a physical change?
(b)Which equation identifies the reactants and products of a combustion reaction?
(c)Which equation is not balanced?
(d)Which is a net ionic equation?
This equation describes the production of tin (II) chloride.\(Sn\left( s \right) + 2HCl\left( g \right) \to SnC{l_2}\left( s \right) + {H_2}\left( g \right)\)Is this a redox reaction? If so, provide a more specific name to the reaction if appropriate, and identify the oxidant and reductant.
Write the net ionic equation representing the neutralization of any strong acid with an ionic hydroxide.
(Hint: Consider the ions produced when a strong acid is dissolved in water)
Determine the oxidation states of the elements in the compounds listed. None of the oxygen-containing compounds are peroxides or superoxides.
