Gold, one of the most sought-after metals in the world, has a density of 19.3 g/cm3, a melting point of 1064 ∘C, and a specific heat of 0.129 J/g ∘C. A gold nugget found in Alaska in 1998 weighed 16.37 lb. A kilogram of 7.44 Part A: What is the melting point of gold in degrees Fahrenheit?

Part B: What is the melting point of gold in kelvins?

Part C: How many kilocalories are required to raise the temperature of the nugget from 490. ∘C to 1064 ∘C?

Part D: If the price of gold is $ 42.16 per gram, what is the nugget worth in dollars?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
