(a) Interpretation: The balance net ionic equation for the reaction of the amphoteric oxide ZnO with hydrochloric acid needs to be determined. Concept introduction: Non-metals forms acidic oxides and tend to form covalent hydride as they have tendency to share their valence electrons to form covalent bond. Metallic oxides are ionic in nature whereas non-metallic oxides are covalent in nature. As the charge on cation increases in oxide, the covalent nature increases due to more polarization of anion from smaller cation.

The balance net ionic equation for the reaction of the amphoteric oxide ZnO with hydrochloric acid needs to be determined.
Concept introduction:
Non-metals forms acidic oxides and tend to form covalent hydride as they have tendency to share their valence electrons to form covalent bond. Metallic oxides are ionic in nature whereas non-metallic oxides are covalent in nature. As the charge on cation increases in oxide, the covalent nature increases due to more polarization of anion from smaller cation.
Interpretation Introduction
(b)
Interpretation:
The balance net ionic equation for the reaction of the amphoteric oxide ZnO with aqueous sodium hydroxide needs to be determined.
Concept introduction:
Non-metals forms acidic oxides and tend to form covalent hydride as they have tendency to share their valence electrons to form covalent bond. Metallic oxides are ionic in nature whereas non-metallic oxides are covalent in nature. As the charge on cation increases in oxide, the covalent nature increases due to more polarization of anion from smaller cation.
What impact would adding twice as much Na2CO3 than required for stoichiometric quantities have on the quantity of product produced? Initial results attached
Given that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based on the results you obtained in this experiment, describe your success in the recovery of calcium carbonate and suggest two possible sources of error that would have caused you to not obtain 100% yield.

5) Calculate the flux of oxygen between the ocean and the atmosphere(2 pts), given that:
(from Box 5.1, pg. 88 of your text):
Temp = 18°C
Salinity = 35 ppt
Density = 1025 kg/m3
Oxygen concentration measured in bulk water = 263.84 mmol/m3
Wind speed = 7.4 m/s
Oxygen is observed to be about 10% initially supersaturated
What is flux if the temperature is 10°C ? (2 pts) (Hint: use the same density in your calculations). Why do your calculated values make sense (or not) based on what you know about the relationship between gas solubility and temperature (1 pt)?
