Answer:
The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity. However, mass and velocity are indirectly related.
Answer:
Explanation:
Potassium nitrate is a soluble salt which readily dissolves in a polar solvent, such as water. When solid potassium nitrate is dissolved in water, it dissociates into potassium cations and nitrate anions.
Due to the resultant ionic charges, the polar water molecules attract the resultant ions and potassium nitrate ions become hydrated, that is, surrounded by water molecules.
Nitrate, our anion, attracts the partially positive ends of water molecules by attracting them via hydrogen atom.
Potassium, the cation, attracts the partially negative end of water molecules by attracting via oxygen atom.
At the anode, half-cell oxidation occurs in a voltaic cell.
<h3>Voltaic Cell Principle</h3>
A voltaic cell generates electricity due to the Gibbs free energy of spontaneous redox processes occurring inside the cell, which is the basis for the voltaic cell's operating principle.
Two half-cells plus a salt bridge make up the voltaic cell. An electrolyte-immersed metallic electrode is present on each side of the cell. These two half-cells are wired together to form a connection to a voltmeter.
<h3>Voltaic Cell Parts</h3>
- Copper makes comprises the cathode of a photovoltaic cell. This electrode serves as the cell's positive terminal, where reduction takes place.
- Anode: Zink metal makes up this electrode. It creates the cell's negative electrode, where oxidation takes place.
- Oxidation and reduction are divided into two discrete parts in two half-cells.
- Salt Bridge: It contains the electrolytes needed to finish the circuit in the voltaic cell.
- The flow of electrons between the electrodes occurs via the external circuit.

The atomic mass is the average of the isotopes of the element meaning most averages of isotopes will not be whole numbers
Answer:
Option c, Two atomic orbitals combine to form one molecular orbital
Explanation:
Molecular orbitals are formed by linear combination of atomic orbitals.
Some of the important facts of molecular orbital theories are as follows:
- No. of the molecular orbitals formed are equal to the no. of atomic orbitals participated.
- Half of the molecular orbitals are bonding molecular orbitals and half of the molecular orbitals are anti bonding molecular orbitals.
- Anti bonding molecular orbitals have energy higher than participating atomic orbitals.
- Bonding molecular orbitals have energy lower than participating atomic orbitals.
- Molecular orbitals are that region in the molecule where electrons are most likely to found.
So, among given, option c which is 'atomic orbitals combine to form one molecular orbital' is incorrect.
