Concept explainers
(a)
Interpretation:
Whether reaction occurs if sodium metal is placed in dilute hydrochloric acid or not has to be determined.
Concept Introduction:
Oxidation process represents loss of electrons. Reduction process represents gain of electrons. Oxidation numbers are the part of system that is formed to track electrons in reaction.
Series formed after arrangement of elements in increasing order of standard reduction potential is called
Metals placed above in electrochemical series from hydrogen have very negative reduction potential and thus they are better reducing agents. Metals placed below from hydrogen in electrochemical series have positive reduction potential and thus they tend to act as an oxidizing agent in a
(b)
Interpretation:
Whether reaction occurs if piece of lead is placed in magnesium nitrate solution or not has to be determined.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Whether reaction occurs if mercury is placed in silver nitrate solution or not has to be determined.
Concept Introduction:
Refer to part (a).

- Closely examine Figure 14.1 and explain why no reaction occurs in part d. Because copper ions have a greater affinity for electrons than zinc ions. Because zinc ions have a greater affinity for electrons than copper ions. Because the temperature is too warm for a reaction to occur.arrow_forwardLead II nitrate solution reacts with a solution of sodium iodide.arrow_forwardSodium hydroxide is added to phosphoric acid.arrow_forward
- When 1.0 mole of solid lead nitrate is added to 2.0 moles of aqueous potassium iodide, a yellow precipitate forms. After the precipitate settles to the bottom, does the solution above the precipitate conduct electricity? Explain. Write the complete ionic equation to help you answer this question.arrow_forwardWhat is G for the following reaction? 2Br(aq)+Cl2(g)Br2(l)+2Cl(aq) Use data given in Table 19.1.arrow_forwardPredict the chemical reactions that will occur at the two electrodes in the electrolysis of an aqueous sodium hydroxide solution.arrow_forward
- The Ostwald process for the commercial production of nitric acid involves the Following three steps: 4NH3(g)+5O2(g)4NO(g)+6H2O(s)2NO(g)+O2(g)2NO2(g)3NO2(g)+H2O(l)2HNO3(aq)+NO(g) a. Which reaction in the Ostwald process are oxidation-reduction reactions? b. Identify each oxidizing agent and reducing agent.arrow_forwardThe sodium level in a patients blood was measured at 137 mmol/L. If 15.0 mL of blood is drawn from this patient, what mass of sodium would be present?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_forward
- The element carbon undergoes many inorganic reactions, as well as being the basis for the field of organic chemistry. Write balanced chemical equations for the reactions of carbon described below. l type='a'> Carbon burns in an excess of oxygen (for example. in the air) to produce carbon dioxide. If the supply of oxygen is limited, carbon will still burn but will produce carbon monoxide rather than carbon dioxide. molten lithium metal is treated with carbon, lithium car bide, Li2C2 , is produced. i>Iron(II) oxide reacts with carbon above temperatures of about 700 °C to produce carbon monoxide gas and molten elemental iron. i>Carbon reacts with fluorine gas at high temperatures to make carbon tetrafluoride.arrow_forwardAn aqueous solution of KBr is placed in a beaker with two inert platinum electrodes. When the cell is attached to an external source of electrical energy, electrolysis occurs. (a) Hydrogen gas and hydroxide ion form at the cathode. Write an equation for the half-reaction that occurs at this electrode. (b) Bromine is the primary product at the anode. Write an equation for its formation.arrow_forwardCopper sulfate, when dissolved in water, has a blue color. When steel wool is mixed with a copper sulfate solution, the steel wool disappears, a brownish solid forms, and the color of the solution changes from blue to green. Circle the choice that lists the best evidence that a chemical reaction occurred. A. The color change from blue to green happens in nature. B. The disappearance of the steel wool shows a new substance is being formed. C. The solid precipitate is a waste product in the reaction. D. Energy is lost in this reaction like all other reactions.
