nikitadnepr [17]2 years ago
6 0

The answer is 42 grams of NaF are there in 1 mole.

<h3>What is a mole ?</h3>

A mole is defined as 6.022 × 10²³ atoms, molecules, ions, or other chemical units.

and the molar mass of a substance is defined as the mass of 1 mole of that substance, expressed in grams per mole.

It is equal to the mass of 6.022 × 10²³ atoms, molecules, or formula units of that substance.

Molar Mass , i.e. mass of 1 mole of NaF is sum of molar mass of Na and F

23 + 19

42 grams

Therefore 42 grams of NaF Sodium-fluoride are there in 1 mole.

Which of the following IS a part of the Kinetic Molecular Theory (KMT)?
Arisa [49]

The statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly. That is option B.

<h3>What is Kinetic Molecular Theory (KMT)?</h3>

Kinetic Molecular Theory (KMT) is defined as the theory that describes the physical behaviour of gases.

The Kinetic Molecular Theory (KMT) include the following:

  • Ideal gas molecules are constantly moving;

  • They have negligible volume;

  • They have negligible intermolecular forces;

  • They undergo perfectly elastic collisions; and

  • They have an average kinetic energy proportional to the ideal gas's absolute temperature.

Therefore, the statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly.

Explain two advantages and disadvantages of using energy created by nuclear fission and nuclear fusion.
alisha [4.7K]
A. NUCLEAR FUSION  is the combination of two atomic nuclei in order to create an atom that in turn creates energy.

A.1 DISADVANTAGES

1. Expensive Construction Costs-
To be able to put up such powerhouse, it needs ostentatious financial support to create a facility and gather experts and scientists.

2. Energy Input vs Energy Output- 
To be able to fuse the two nuclei together, there is a great demand for high levels of heat. Thus to be able to produce large amount of energy, it also needs a large amount of thermal energy which is not reasonable enough.

A.2 ADVANTAGES

1. Barely Any Waste- 
the only by product of nuclear fusion is helium and it is non toxic. This does not cause any harm to the environment and to people.

2. Unlimited Fuel- 
All of the components needed to produce energy can be made. Deuterium, which is the main ingredient needed to supply a truly unlimited and sustainable energy supply, can be distilled from the sea water.


B. NUCLEAR FISSION- refers to the process of splitting of the nucleus of an atom into several smaller particles to produce free neutrons and lighter elements.

B.1 DISADVANTAGES

1. It can be dangerous for employees- 
Radiation which is one of the byproducts of nuclear fission can be harmful to the personnel working within its premises.

2. It has high initial expenses- 
Nuclear power plants needs a specialized equipment for it to become functional. 

B.2 ADVANTAGES


1. It helps minimize environmental pollution- 
Nuclear power plants can produce large amounts of energy while consuming relatively minimal amount of fossil fuel. To explain further, consumption and usage of fossil fuel poses adverse effect in the environment because it can emit carbon dioxide and other harmful chemicals.

2. It helps reduce global warming- If the world would opt for nuclear fission, then there would be less greenhouse gasses in the atmosphere. This in turn would mitigate global warming.

Answer:

  The purpose of this guide is to help you write a clear and concise report that summarizes the lab I just completed.  This lab showed me how water carries rocks to a new location. For instance how the first model showed how a stream would act with light drizzle to downpour as I saw the outcomes were all if not completely then partially different  

            I read the information that was given to me before I started each lab lesson and went on from there.
