Answer : The type of compound created is Ionic compound and the chemical formula is KCl.
Explanation :
- Potassium has 1 electron in its valence shell and chlorine has 7 electrons in its valence shell.
- The potassium loses 1 valence electron & make a positive charged ion and chlorine picks it up & make a negative charged ion and then they attract to each other.
- Potassium and chlorine atom combine to form potassium chloride by the ionic bonding.
- An ionic compound is made of a metal and non-metal element. And in this case, potassium is a metal element and chlorine is a non-metal element.
The ionic compound formation is,
The Chemical formula is KCl.
Answer:
To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction. If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced.
Bohr's model explained the position of the electron, proton, and neutron in the atom of the element. The energy at the n = 2 level of the atom will be - 3.40 eV.
<h3>What is the principal quantum number (n)?</h3>
The principal quantum number (n) has been the distance of the electron of that atom in the nucleus and its energy in the structure. It can also be said to define the size of the atomic orbit.
n = 2 is the first excited state whose energy is calculated as:
Eₙ = − 13.6 ÷ n² eV
E₂ = - 13.6 eV ÷ 2²
= -3.40 eV
Therefore, -3.40 eV is the energy of electron at n = 2.

Answer:
Explanation:
Hello,
In this case, since the solution is formed by sodium chloride and water, we understand that for one mole of solution, we have 0.132 moles of sodium chloride and 0.868 moles of water, therefore, by using their molar masses we can compute their masses in the solution:
Thereby, we can compute the weight/weight percent as follows:
So we use the previously computed masses:
Best regards.
