Answer:
C. Fluorine because the model has 9 protons which is represented by the atomic number
Explanation:
We usually identify an element by the number of protons in them. The number of protons is the atomic number of an atom.
- Every atom has a specific number of protons in them.
- This number of protons is the atomic number.
- According to the periodic law, atoms are arranged on the periodic table based on their atomic number.
- The given fluorine atom has 9 protons which represents the atomic number of the atom.
- This way, the given number clearly shows the right model for identifying the chemical specie.
Answer:
D 2,2
Explanation:
We can see that there are 2 chlorines on the reactant side so there has to be a 2 on the product side
Now we have Na + Cl2 --> 2NaCl
The problem now is that there are 2 sodiums on the product side so add a 2 to the Na on the reactant side
2Na + Cl2 --> 2NaCl
Now it's balanced!
Based on factors affecting solution formation;
- Strong solvent-solute intermolecular forces favors solution formation.
- Increase in entropy favours solution formation
- Decrease in enthalpy favours solution formation
<h3>What is a solution?</h3>
A solution is a substance formed when a substance known as solute dissolves in another substance know as solvent.
Factors that affect solution formation include:
- strength of intermolecular forces between solute and solvent
- entropy
- enthalpy
Strong solvent-solute intermolecular forces favors solution formation.
Increase in entropy favours solution formation
Decrease in enthalpy favours solution formation.
