Answer:
bond
Explanation:
It is a polar bond because it is when two atoms bond
Answer:
7.23 J
Explanation:
Step 1: Given data
- Mass of graphite (m): 566.0 mg
- Initial temperature: 5.2 °C
- Final temperature: 23.2 °C
- Specific heat capacity of graphite (c): 0.710J·g⁻¹K⁻¹
Step 2: Calculate the energy required (Q)
We will use the following expression.
Q = c × m × ΔT
Q = 0.710J·g⁻¹K⁻¹ × 0.5660 g × (23.2°C-5.2°C)
Q = 7.23 J
Answer:
its endothermic .
because your using a cooling process instead of a heating process if it was a heating process it would be exothermic
First one false second one true
Answer:
Sn < Brass ≈ Zn < Al
Step-by-step explanation:
Sn < Brass ≈ Zn < Al
C/J·°C⁻¹g⁻¹: .0.246 < 0.418 ≈ 0.419 < 0.734
