Answer:
The final temperature of the iron is:- 38.0 °C
Explanation:
The initial temperature = 24.7 °C
Let Final temperature = T °C
Using,
Q = m C ×ΔT
Where,
Q is the heat absorbed by the iron = 85.7 J
C gas is the specific heat of the iron = 0.45 J/g °C
m is the mass of iron = 14.3 g
ΔT is the change in temperature. ( T - 24.7 ) °C
Applying the values as:
<u>Q = m C ×ΔT </u>
85.7 J = 14.3 g × 0.45 J/g °C × ( T - 24.7 ) °C
Solving for T, we get that:-
T = 38.0 °C
<u>The final temperature of the iron is:- 38.0 °C</u>
Explanation:
There is a clear cut difference between a compound and an element:
- A compound is made up of substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
- An element is a distinct substance that cannot be split-up into simpler substances. These substances are only made up of one kind of atom.
Compounds are formed so that unstable elements can attain stability.
Carbon monoxide is made up two elements: Carbon and oxygen that have combined chemically together.
- Carbon monoxide is a toxic gas and it is different from oxygen atom and carbon atom.
- Carbon is a solid but carbon monoxide is a gas.
- Oxygen atom does not exists on its own but it exists as Oxygen gas O₂
- The properties of carbon monoxide clearly differ from that of oxygen and carbon.
