Answer: There are 3 triple points in the given phase diagram.
Explanation: Triple point is defined as the point at which the temperature and pressure of the 3 phases are in equilibrium with each other.
In the given phase diagram, there are three points which is satisfying this definition.
Point A: At this point The monoclinic form and rhombic form have the same vapor pressure. Hence,
Point B: At this point, the monoclinic form starts to melt. Hence,
Point C: At this point, the rhombic form, monolinic form and liquid is in equilibrium. Hence,
Hence, this system has 3 triple points.
Answer:
5.4
Explanation:
The lower the pH the more H3o+ ions there are
<h3>
Answer:</h3>
12 neutrons
<h3>
Explanation:</h3>
- A neutral atom is an atom that has no charge, which means it has no additional electrons or electrons removed from its energy levels.
- An atom is made up of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
- The number of protons in the nucleus of a neutral atom is known as the atomic number.
- In a neutral atom, the atomic number is equal to the number of electrons as protons are equal to the number of electrons.
- The sum of protons and neutrons in the nucleus of an atom is known as the mass number of an atom.
Therefore;
Protons = Atomic number
Protons + neutrons = Mass number
Thus;
Neutrons = Mass number - protons or
= Mass number - atomic number
In this case;
Atomic number = 11
Mass number = 23
Thus;
Neutrons = mass number - atomic number
= 23 - 11
= 12 neutrons
Option B
Explanation:
Hydroelectric power plants works by converting kinetic energy to mechanical and then electrical energy in the generator.
- Hydroelectric power plants produces electricity through a step wise process aimed at converting energy.
- Moving water is first dammed in a reservoir to ensure regular and year round supply of water.
- The reservoir water is then passed through a channel .
- Moving water possess kinetic energy which is the energy due to the motion of a body.
- This kinetic energy is channeled to driving motor parts in a generator using a turbine.
- This is mechanical energy.
- As the turbine rotates electrical energy is produced.
- Hydroelectric power generation is a renewable source of energy.
