A CHEMICAL PROPERTY is a characteristic of matter that describes its ability to change into a different substance. When elements undergo chemical reaction, they experience a breakage in the chemical bonds that hold their particles together, new chemical bonds are then formed; this makes them to become a new substance.
Answer:
c and o
Explanation:
Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals.
- To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
- This leads the bond formation.
- Carbon is a non-metal, with oxygen, they will prefer to form a covalent bond where they share their electrons
The value for ΔG = 18 kJ/mol
<h3>Further explanation</h3>
Given
ΔH = 27 kJ/mol and ΔS = 0.09 kJ/mol.K
T = 100 K
Required
the value for ΔG
Solution
The spontaneous process of a reaction is based on 2 factors :
- enthalpy change ΔH decreases and
- entropy change ΔS increases
ΔG=ΔH-T.ΔS
Chemical is the answer to the question, but nuclear could also be a valid one since it is nearly impossible to reverse that.
