A single replacement reaction could look like this:
2FeCl3 + 3Ba ➡️ 3BaCl2 + 2Fe
In this reaction, the barium is replacing the iron bound to the chlorine.
Answer:
0.4167 J/°C.g.
Explanation:
- To solve this problem, we can use the relation:
<em>Q = m.c.ΔT,</em>
where, Q is the amount of heat absorbed by substance (Q = 2500 J).
m is the mass of the substance (m = 100 g).
c is the specific heat of the substance (c = ??? J/°C.g).
ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = 70°C - 10°C = 60°C).
∵ Q = m.c.ΔT
<em>∴ c = Q/(m.ΔT) </em>= (2500 J)/(100 g)(60°C) = <em>0.4167 J/°C.g.</em>
