(a)
Interpretation:
The indicated has to be completed if it is possible.
Concept Introduction:
The relative ease of reactivity or oxidation of metals can be readily determined from activity series that describes the least reactive to the most reactive metal.
In displacement reactions metals that lie above in the activity series are able to readily displace metals from their salt solutions that lie beneath in the same series due to more reactivity. Sodium, potassium and similar alkali and alkaline earth metals occupy higher positions while gold, silver and platinum like inert metals lie at the bottom.

- 4.80 The reaction shown below is used to destroy Freon-12 (CF2Cl2), preventing its release into the atmosphere. What mass of NaF will be formed if 250.0 kg of CF2Cl2 and 400.0 kg of Na2C2O4 are heated and allowed to react to completion? CF2Cl2+2Na2C2O42NaF+2NaCl+C+4CO2arrow_forwardPhysiological saline concentration—that is, the sodium chloride concentration in our bodies—is approximately 0.16 M . A saline solution fur contact lenses is prepared to match the physiological concentration. If you purchase 25 mL of contact lens saline solution, how many grams of sodium chloride have you bought?arrow_forwardWhat do we call reactions in which electrons are transferred between atoms or ions? What do we call a loss of electrons by an atom or ion? What is it called when an atom or ion gains electrons? Can we have a process in which electrons are lost by one species without there also being a process in which the electrons are gained by another species? Why? Give three examples of equations in which there is a transfer of electrons between a metallic element and a nonmetallic element. In your examples, identify which species loses electrons and which species gains electrons.arrow_forward
