Answer: Nuclear fusion and Nuclear fission

Explanation: Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.

Nuclear fission is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.

The binding energy which is the energy which keeps the neutrons and protons intact in the nucleus is being released during nuclear reactions.

Hi my dear friend,

What are the two processes by which nuclear energy is released? Briefly describe the processes.

Ans: The two processes by which nuclear energy is released are nuclear fusion and nuclear fission. Nuclear fusion occurs when two smaller atoms are combined into a larger atom.

The Car and The Wall

According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. ... Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts.

When the car makes contact with the barrier, there is reaction of equal magnitude that arises from the car making contact with the barrier. The reaction force is easily visible in a car crash, which is why it is such a great way to show how Newton's Third Law can be applied to our lives.

How can you distinguish between a physical change and a chemical change?

AleksAgata [21]

Answer:

Physical Change

When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.
Physical change is a temporary change.
A Physical change affects only physical properties i.e. shape, size, etc.
A physical change involves very little to no absorption of energy.
Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. .
In a physical change, no new substance is formed.
Physical change is easily reversible i.e original substance can be recovered.

Chemical Change

When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.
.A chemical change is a permanent change.
Chemical change both physical and chemical properties of the substance including its composition
During a chemical reaction, absorption and evolution of energy take place.
A few examples of chemical change are digestion of food, burning of coal, rusting, etc.
A chemical change is always accompanied by one or more new substance(s).
Chemical changes are irreversible i.e. original substance cannot be recovered.

A sample of gas at 310 Kelvin and 1.2 atmospheres has a density of 2.78 g/L. What is the molar mass of this gas?

Troyanec [42]

Ideal gas law PV = nRT or PM = dRt ( M is molecular mass of gas ) and d is gas density
where m/ M ( m is mass of gas sample )

m = dRT / P ( 2.78 g/L ) ( 0.082 L atm/ K mole )( 310K ) / 1.2 atm =
58.9 g/mol

gas must be butane ( C4H10) has molecular mass = 58.9 g/mol
