Answer:
The metallic elements have more metallic characteristcis.
Explanation:
- Metallic character is the name given to a set of common properties shared by the metallic elements.
- Metallic luster, high density, high electric and thermal conductivity are some physical properties associated with metallic characters.
- Malleability and ductility is also an important metallic characteristic.
- Generally the metals are hard and dense.
- The elements on the left hand side of the periodic table show metallic characteristics except hydrogen.
Answer:
36365.4 Joules
Explanation:
The quantity of Heat Energy (Q) released on cooling a heated substance depends on its Mass (M), specific heat capacity (C), and change in temperature (Φ)
Thus, Q = MCΦ
Since, M = 45.4 g
C = 3.56 J/g°C,
Φ = 250°C - 25°C = 225°C
Q = 45.4g x 3.56J/g°C x 225°C
Q= 36365.4 Joules
Thus, 36365.4 Joules of heat energy is released when the lithium is cooled.
