<u>Answer:</u> The change in temperature is 84.7°C
<u>Explanation:</u>
To calculate the change in temperature, we use the equation:
where,
q = heat absorbed = 1 kCal = 1000 Cal (Conversion factor: 1 kCal = 1000 Cal)
m = mass of steel = 100 g
c = specific heat capacity of steel = 0.118 Cal/g.°C
= change in temperature = ?
Putting values in above equation, we get:
Hence, the change in temperature is 84.7°C
Answer: I think it would be -23
Explanation:
Answer:
there might be different chemicals in each thing so the effects are different
the equation balanced is
3 PbI4 + 4 CrCl3 → 3 PbCl4 + 4 CrI3
So, the short answer is: burning is irreversible because it involves a chemical reaction, while melting is reversible because it's just a phase change.
