Given the chemical equation:  4KO2 (s) + 2CO2 (g) > 2K2CO3 (s) + 3O2 (g) Indicate the oxidation number for each atom involved in the reactants: "K" , "O" in KO2 , "C" , "O" in CO2

Balance the chemical equation below using the smallest possible whole number stoichiometric coefficients. Fe(s) + O₂(g) + H₂O(1) → Fe(OH)₂ (aq) ロ→ロ X 3

Please answer the following pertaining to analytical chemistry.

6Br (aq) +Cr2O,2- (aq) +14H* (aq) → 3BR2 (g)+2Cr3+ (aq) +7H2O1) Which element is oxidized? Which element is reduced? What is the reducing agent? Oxidizing agent?

Add the oxidation numbers of the following atoms in the compounds: Compound Atoms S: 1 SO2 0: 2 С: 1 co,2- 0: 3 Со: 1 COF2 F: 2

Please write the whole reducing and oxidizing agents. This will help me

In the following reaction, which element in what species is oxidized? C,H, (g) + 3 0, (g) → 2 CO, (g) + 2 H,0 (g)

Decide whether each chemical reaction in the table below is an oxidation-reduction ("redox") reaction. If the reaction is a redox reaction, write down the formula of the reducing agent and the formula of the oxidizing agent.

In the reaction FeCl 3 (s) + H2 (g) → 3HCI (g) + Fe (s), Cl acts as a reducing agent neither a reducing nor oxidizing agent

Assign oxidation states to all of the species in the following redox reaction. For the reactants, identify electron loss or gain, the species oxidized, the species reduced, the oxidizing agent and the reducing agent. Oxidation state Electron loss or gain Oxidized or reduced Reducing or oxidizing agent Mg(s) ♥ ◊ ŵ +2Fe³+ (aq)- → ◊ ♥ ◊ ◊ Mg2+ (aq) + 2Fe²+ (aq) ◊
