So, the question would would probably ask if the gold ring is indeed pure gold. Let's calculate the specific heat capacity of the calorimeter. If this is equal to the given specific heat for pure gold, then the the gold ring is pure gold.
Qwater = mCdT = (50 g)(4.18 J/gC)(31 - 23.7) = 1525.7 J
Through conservation of energy,
Qwater = Qcalorimeter = mCdT = 1525.7
1525.7 = (10.5)(C)(78.3 - 31)
Solving for C,
C = 3.072 J/gC
Since the specific heat of the calorimeter is not equal to that of the pure gold (0.1291 J/gC), then the gold ring is not pure.
They are volcanoes
The difference between a quiet and explosive eruption is the silica content. In a quiet eruption, the magma is low in silica, allowing the magma to flow out gently. In an explosive eruption, the magma is high in silica, which causes the magma to be thick and sticky.
Answer:
This question appears incomplete
Explanation:
However, a glassware/instrument that is used to carry out small reactions is a beaker. It is a cylindrical instrument usually made of glass (so as not to take part in the reaction). It can also be put over a bunsen burner to heat up its content in the process of a chemical reaction. It is quite ideal for small reactions.
Girlllll idkkkkknim just tryna get pointtttt
ANSWER: The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe
