(a)
Interpretation:
Balanced equation for two examples of precipitation reactions should be given.
Concept Introduction:
If in any reaction formation of solid takes place from the aqueous solution, the reaction is known as precipitation reaction.
(b)
Interpretation:
Balanced equation for two examples of single displacement reactions should be given.
Concept Introduction:
The reaction in which aqueous solution of one substance reacts with aqueous solution of other substance in such a way that one of the ions replaces the ion in other substance is known as a displacement reaction.
(c)
Interpretation:
Balanced equation for two examples of combustion reactions should be given.
Concept Introduction:
Combustion reactions are defined as reaction of compounds with oxygen rapidly producing energy as heat.
(d)
Interpretation:
Balanced equation for two examples of synthesis reactions should be given.
Concept Introduction:
When a given compound is prepared using simpler materials, we call it a synthesis reaction. The reactants may be elements or compounds.
(e)
Interpretation:
Balanced equation for two examples of
Concept Introduction:
Driving force that tends an oxidation-reduction reaction to happen is transfer of electrons between atoms or ions. Atoms or which lose electrons are oxidized and atoms or ions which take up those electrons are reduced.
(f)
Interpretation:
Balanced equation for two examples of Decomposition reactions should be given.
Concept Introduction:
When compounds are broken down to simpler compounds or all the way to its elements, it is called a decomposition reaction.
(g)
Interpretation:
Balanced equation for two examples of acid-base neutralization reactions should be given.
Concept Introduction:
Acid-base neutralization reaction represents the reaction of acid and base to give salt and water. Acid is a substance that gives H+ ion in the aqueous solution and base is a substance that gives hydroxide ion in the aqueous solution. The hydrogen ion from acid and hydroxide ion from base reacts to give water. Similarly, the conjugate base from acid and conjugate acid from base reacts to give salt.
The general acid base reaction is as follows:
The pH of a solution after neutralization reaction is 7.

- The carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day. Assume that each astronaut requires 2.50 103 kcal of energy per day. Further assume that this energy can be equated to the heat of combustion of a quantity of glucose, C6H12O6, to CO2(g) and H2O(l). From the amount of glucose required to give 2.50 103 kcal of heat, calculate the amount of CO2 produced and hence the amount of LiOH required. The H for glucose(s) is 1273 kJ/mol.arrow_forwardWhat is Hrxn for reaction of iron(III) oxide and carbon monoxide to give iron metal and carbon dioxide gas? Use the following reactions: 4Fe(s)+3O2(g)2Fe2O3(s)H=1648.4kJ4CO(g)+O2(g)2CO3(g)H=565.98kJarrow_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
- A novel process for obtaining magnesium from sea water involves several reactions. Write a balanced chemical equation for each step of the process. (a) The first step is the decomposition of solid calcium carbonate from seashells to form solid calcium oxide and gaseous carbon dioxide. (b) The second step is the formation of solid calcium hydroxide as the only product from the reaction of the solid calcium oxide with liquid water. (c) Solid calcium hydroxide is then added to the seawater, reacting with dissolved magnesium chloride to yield solid magnesium hydroxide and aqueous calcium chloride. (d) The solid magnesium hydroxide is added to a hydrochloric acid solution, producing dissolved magnesium chloride and liquid water. (e) Finally, the magnesium chloride is melted and electrolyzed to yield liquid magnesium metal and diatomic chlorine gas.arrow_forwardClassify each of the following reactions as (1) a redox reaction (2) a nonredox reaction or (3) cant classify because of insufficient information. a.
