Answer #1

A 1.6-g
sample of a metal that has the appearance of gold requires 5.8J of
energy to change it’s temperature from 23C to 41 C. Is the metal
pure gold?
B If 294J
of heat is transferred to a 10.0 g sample of silver at 25⁰C, what
is the final temperature of the silver?

Problem 5.54
A 100.0-g bar of gold is heated from 25 ∘C to 50 ∘C during which
it absorbs 322 J of heat. Assume the volume of the gold bar remains
constant.

The equilibrium constant, Kp, for the reaction is:

What quantity of energy, in joules, must be removed from a 164-g
sample of CH3Cl(g) that is initially at 24.95°C to its condensation
point, -24.09°C and then change the gas to a liquid at that
temperature?

a 36.9g sample of metal is heated to 100.0 degrees celcius, and
then added to a calorimeter containing 141.5g of water at 23.1
degrees celcius. the temperature of the water rises to a maxiumum
of 25.2 degrees celcius before cooling back down.
a) did the water absorb heat or did it release heat?
b) how many joules of heat was exchanged between the water and
the metal?
c) what is the identity of the metal?

A 35.7 gram sample of iron (heat capacity 0.45 g/J°C) was heated
