Question

Identify the correct net ionic equation for the reaction that occurs when solutions of Na_3 PO_4 and Ca(NO_3)_2 are mixed. 2Na_3 PO_4 (eq) + 3Ca(NO_3)_2 (eq) rightarrow 6Na NO_3 (s) + Ca_3 (PO_4) _2 (s) Na^+ (eq) + NO_3^- rightarrow NaNO_3 (s) Na^+ (eq) + Ca^2+ (eq) + PO_4^3- (eq) rightarrow NaCaPO_4 (s) Ca^2+ + PO_4^2- (eq) rightarrow CaPO_4 (s) 3Ca^2+ (eq) + 2PO_4^3- (eq) rightarrow Ca_3 (PO_4) _2 (s) What is the oxidation state of carbon in sodium carbonate (Na_2 CO_3)? +2 -2 +4 -4 In the following reaction, which substances are the reducing and oxidizing agents? 2Mg(s) + O_z (g) rightarrow 2MgO(s) Mg is the reducing agent; MgO is the oxidizing agent MgO is the reducing agent; Mg is the oxidizing agent Mg is the reducing agent; O_2 is the oxidizing agent O_2 is the reducing agent; Mg is the oxidizing agent None of the above are correct.

Explanation / Answer

7-A,

8-A,

9-C

Magnesium gradually loss of the electron so it is reducing oxygen taking of electrons so it oxidizing agent
