(a)
Interpretation:
The true statement about the oxidation number of elemental substance is to be predicted.
Concept introduction:
Oxidation number indicates the number of electron lost or gained by an atom in the compound. The oxidation number can be negative or positive or zero. It is also known as oxidation state. It is assigned to the elements in the chemical formula.
(b)

- Write the net ionic equation for the reaction, if any, that occurs on mixing (a) solutions of sodium hydroxide and magnesium chloride. (b) solutions of sodium nitrate and magnesium bromide. (c) magnesium metal and a solution of hydrochloric acid to produce magnesium chloride and hydrogen. Magnesium metal reacting with HCl.arrow_forwardThe ampere unit is used to describe the flow of electricity in an electrical circuit. One ampere is an amount of electricity corresponding to the flow of 6.21018 electrons past a point in a circuit in 1 second. In a hydrogen fuel cell, hydrogen atoms are dissociated into H+ ions and electrons (HH++1e). How many grams of hydrogen must be dissociated each second in a fuel cell to produce 1.0 ampere of electricity?arrow_forwardThe iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion. A 5.00-g sample of hemoglobin requires 32.3 mL of a 0.002100 M solution of potassium permanganate. The reaction with permanganate ion is MnO4(aq)+8H+(aq)+5Fe2+(aq)Mn2+(aq)+5Fe3+(aq)+4H2O What is the mass percent of iron in hemoglobin?arrow_forward
- Complete and balance the following acid-base equations: (a) A solution of HClO4 is added to a solution of LiOH. (b) Aqueous H2SO4 reacts with NaOH. (c) Ba(OH)2 reacts with HF gas.arrow_forwardIn an ordinary flashlight battery, an oxidation reaction and a reduction reaction rake place at different locations to produce an electric current that consists of electrons. In one of the reactions, the zinc container of the battery slowly dissolves as it is converted into zinc ions. Is this the oxidation or the reduction reaction? Is this reaction the source of electrons, or are electrons used to carry out the reaction? Explain your answers with a reaction equation.arrow_forwardComplete and balance the equations for the following acid-base neutralization reactions. If water is used as a solvent, write the reactants and products as aqueous ions. In some cases, there may be more than one correct answer, depending on the amounts of reactants used. (a) Mg(OH)2(s)+HCl4(aq) (b) SO3(g)+H2O(l) (assume an excess of water and that the product dissolves) (c) SrO(s)+H2SO4(l)arrow_forward
- Which of the following compounds have the same oxidation level, and which have different levels?arrow_forward4.112 A metallurgical firm wishes to dispose of 1300 gallons of waste sulfuric acid whose molarity is 1.37 M. Before disposal, it will be reacted with calcium hydroxide (slaked lime), which costs $0.23 per pound. (a) Write the balanced chemical equation for this process. (b) Determine the cost that the firm will incur from this use of slaked lime.arrow_forwardSodium hydroxide is added to phosphoric acid.arrow_forward
