Two electron pairs is the answer
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
Hello !!
I think the answer will be is :
<h2>
B. Elements are different kinds of atoms.</h2><h2>
</h2>
Because when the atom changed it's means it's different types of the atom.

Edit the question
Then attach the file yu want
IF no fie,Save it
Then attach it
At STP, copper (Cu) would be the only substance here that will exist in the solid state.
