D. all of these
Explanation:
All of given choices are the physical properties of the gold as given by the table.
Color is also a physical property.
Ionization potential and electronegativity are chemical properties of the metal.
The physical property of a substance tells us everything about a substance when no change is occurring to it.
Such properties are observed with our sense or instruments or pieces of apparatus.
- Examples are color of matter, state of matter, odor, taste, density, boiling point, melting point, solubility, hardness, texture etc

Answer:
Examples of how the ideas can be applied to the issues and practices of hydraulic fracturing for the acquisition of shale gas are;
Reuse; The produced water in obtained from oil and gas well production are reused for fracking, drilling, and if the water is good enough, it can be used for farming
Reduce; The use of recycled brine and water in drilling and fracking process reduces the application of freshwater in the those processes and reduces pollution of natural water sources
Recycle; Recycling involves creating products from waste. In the hydraulic fracturing process approximately 13 percent of the water produced and the flowback water are recycled to be used more than once thereby reducing the net consumption of freshwater
Explanation:
In hydraulic fracturing, also known informally as fracking, is the drilling method used in oil and gas well development process that makes use of water sand and chemical injection through the well bore to open and widen cracks in the bedrock formations in the areas around the wellbore.
