Chapter 22: Problem 57

Sodium nitrite can be made by passing oxygen and nitrogen monoxide gases into an aqueous solution of sodium carbonate. Write a balanced equation for this reaction.

Short Answer

Expert verified
The balanced equation for the reaction is 2O2 + 4NO + Na2CO3 -> 2NaNO2 + CO2.

Step by step solution

01

Identify Reactants and Products

Firstly, the reactants are oxygen (O2), nitrogen monoxide (NO), and sodium carbonate (Na2CO3). These react to form Sodium Nitrite (NaNO2) as the needed product.
02

Write Unbalanced Chemical Equation

The unbalanced equation is given as: O2 + NO + Na2CO3 -> NaNO2. This shows the reactants and the product but does not account for the law of conservation of mass yet.
03

Balance The Equation

To balance the equation, coefficients are adjusted before each substance until the same number of each type of atom exists on both the left and the right side of the equation. The balanced equation becomes: 2O2 + 4NO + Na2CO3 -> 2NaNO2 + CO2. This means 2 moles of O2 reacts with 4 moles of NO and 1 mole of Na2CO3 to produce 2 moles of NaNO2 and 1 mole of CO2.

Use information from this chapter and previous chapters to write chemical equations to represent the following: (a) equilibrium between nitrogen dioxide and dinitrogen tetroxide in the gaseous state (b) the reduction of nitrous acid by \(\mathrm{N}_{2} \mathrm{H}_{5}^{+}\) forming hydrazoic acid, followed by the reduction of additional nitrous acid by the hydrazoic acid, yielding nitrogen and dinitrogen monoxide (c) the neutralization of \(\mathrm{H}_{3} \mathrm{PO}_{4}(\mathrm{aq})\) to the second equivalence point by \(\mathrm{NH}_{3}(\mathrm{aq})\).

All of the following have a tetrahedral shape except (a) \(\mathrm{SO}_{4}^{2-} ;\) (b) \(\mathrm{XeF}_{4} ;\) (c) \(\mathrm{CCl}_{4} ;\) (d) \(\mathrm{XeO}_{4} ;\) (e) \(\mathrm{NH}_{4}^{+}\)..

Which of the following species has a linear structure: \(\mathrm{ClF}_{2}^{+}, \mathrm{IBrF}^{-}, \mathrm{OCl}_{2}, \mathrm{ClF}_{3},\) or \(\mathrm{SF}_{4} ?\) (Central atom underlined.) Do any two of these species have the same structure?

Peroxonitrous acid is an unstable intermediate formed in the oxidation of \(\mathrm{HNO}_{2}\) by \(\mathrm{H}_{2} \mathrm{O}_{2}\). It has the same formula as nitric acid, HNO \(_{3}\). Show how you would expect peroxonitrous and nitric acids to differ in structure.

On the basis of molecular orbital theory, would you expect \(\mathrm{NH}_{2}^{+}\) to be linear or bent?
