Answer:
C) ionic compounds
Explanation:
Addition of ionic compounds, such as inorganic salts, to pure water causes the greatest increase in conductivity because these substances are strong electrolytes and completely dissociate and produce ions.
1 mole contains 6.02 * 10^23 molecules
0.578 moles of water contains 0.578 * 6.02 * 10^23 molecules
Answer:
Since the melting point of iron (1538 C) is higher than the Curie point (770 C), the recast iron will lose its original magnetism. After the iron has cooled below the Curie point, it can be re-magnetized.
