A silver cube with an edge length of 2.42 cm and a gold cube with an edge length of 2.81 cm are both heated to 88.8 ∘C and placed in 110.5 mL of water at 19.9 ∘C . What is the final temperature of the water when thermal equilibrium is reached?Substance Specific heat (J/g·°C) Density (g/cm3) gold 0.1256 19.3 silver 0.2386 10.5 water 4.184 1.00

your answer is c) plasma

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.
