It’s called an isotope which is an atom with the same number of protons but a different number of neutrons
The photo is not visible re ask
It is absorbing because it is going through endothermic process (absorbing heat) and the change in color means it is undergoing a chemical reaction
Answer:
0.13 J/g.°C.
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 lead (Q = 29.0 J).
m is the mass of lead (m = 15.0 g).
c is the specific heat capacity of lead (c = ??? J/g.°C).
ΔT is the temperature difference (final T - initial T) (ΔT = 37 °C - 22 °C = 15.0 °C).
∵ Q = m.c.ΔT
<em>∴ c = Q/m.ΔT </em>= (29.0 J)/(15.0 g)(15.0 °C) = <em>01288 J/g.°C ≅ 0.13 J/g.°C.</em>
