Describe how and why gasses can be compressed much more than solids. NaCl does not conduct electricity in solid-state, however, it conducts in molten and solution form. Explain this phenomenon. Explain why the copper element has two ion charges. Why does cold metal conduct electricity better ...
The ratio of the current density in the material to the electric field that produces the flow of current is used to calculate the degree to which a certain material conducts electricity. The measure of how electric current travels throughout a substance is referred to as electric conduct...
In fact, it behaves much more like a metal (though the way it conducts electricity is very different), and that's led some scientists to describe it as a semimetal or a semiconductor (a material mid-way between a conductor and an insulator, such as silicon and germanium). Even so, it...
Explain why the copper element has two ion charges. Can you get metallic Iron out of Fe2O3? If yew, how? Explain what is happening at the atomic level in steel that has been "work hardened"? What is a material that is malleable and conducts electricity? Why are carcinogens (such as...
What is a material that is malleable and conducts electricity? Which cation is more strongly hydrated, Fe3+ or Fe2+? Explain. Cite some properties that are characteristic of a metal. Briefly explain the physical and oxidizing properties of potassium permanganate (KMnO4). ...
NaCl does not conduct electricity in solid-state, however, it conducts in molten and solution form. Explain this phenomenon. What structure features does acetylsalicylic acid have that prevents if from causing iron (III) chloride to change color? Define briefly: a) boiling point. b) melting poin...
How does electrolyte conductivity affect corrosion rate? Explain why the copper element has two ion charges. Is SrSO4 an electrolyte or a non-electrolyte? Explain. NaCl does not conduct electricity in solid-state, however, it conducts in molten and solution form. E...
How to produce Hydrogen gas? Describe the positions of atoms. Compare and explain the differences between a lead-acid battery and a dry-cell battery. Explain why metals conduct electricity. In terms of structure, explain why a water solutio...
(b) Explain why tap water conducts electricity. How does reverse osmosis produce drinkable water from ocean water? Explain the process. What is the term for the process in which an ion is surrounded by water molecules arranged in a specific manner? Explain how substances that are electrolytes ...
Describe how and why atropine is used in the treatment of bradycardia. Why does both an electrolyte and non-electrotype solution affect toxicity but only an electrotype solution affect conductivity? Explain why aqueous solution of sodium chloride conducts electricity where as solid sodium chloride does...
