The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.

<h3>Why is the energy released in a reaction?</h3>

Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.

The quantity of energy released in reactions differs according to the reaction type involved.

When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.

The energy, E released in nuclear reactions is given by the formula below:

$E = mc^{2}$

where m is the mass of the substance and c is the speed of light.

Therefore, the energy released in nuclear reactions are far larger than that released in chemical reactions.

Name the person who developed a table of elements which revealed

aivan3 [116]

Dimitry Mendeleef

Explanation:

Dimitry Mendeleef developed a table of elements which revealed regularities in elemental properties. He discovered the periodic arrangement of elements in 1869 while playing his game of solitaire.

John Newlands in in 1863 proposed the idea of a repeating octaves of properties of elements.
Dimitry Mendeleef described the periodic table or chart in 1869
The chart was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
In his periodic table, elements were arranged by atomic weights with recurring properties in a periodic manner>

wolverine [178]

The only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.

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

A triangle can be defined as a one of the plane shapes which has three sides and three angles

So therefore, the only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.

What volume (in L) of oxygen will be required to produce 77.4 L of water vapor in the reaction below?

Nostrana [21]

Answer:

For the production of 77.4 L water 90.3 L oxygen is required.

Explanation:

Given data:

Volume of oxygen required = ?

Volume of water produced = 77.4 L

Solution:

Chemical reaction equation:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

1 mole = 22.414 L

There are 6 moles of water = 6×22.414 = 134.5 L

There are 7 moles of oxygen = 7×22.414 = 156.9 L

Now we will compare the litters of water and oxygen:

H₂O : O₂

134.5 : 156.9

77.4 : 156.9/134.5×77.4 =90.3 L

So for the production of 77.4 L water 90.3 L oxygen is required.
