Explanation:
Chemical reaction equation for the give decomposition of 
is as follows:.
And, initially only is present.
The given data is as follows.
= 2.3 atm at equilibrium
= 0.69 atm
Therefore,
= 0.23 aatm
So, = 2.3 - 2(0.23)
= 1.84 atm
Now, expression for 
will be as follows.
= 
= 0.0224
or, 
Thus, we can conclude that the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture is 
.
Answer:
The color of light in which plants are less likely to produce food is green.
Explanation:
Photosynthesis is the process by which plants take advantage of sunlight to convert it into chemical energy, necessary to manufacture their nutrients, their growth and development.
Plants do not absorb all the colors of the light spectrum, since due to their pigments they absorb colors with specific wavelengths. Green plants do not absorb the color green, but reflect it —due to the chlorophyll pigment— which gives the green color to those leaves.
For this reason, the <u>light that plants take least advantage of to produce food is green light</u>.
Other options:
<em> The colors blue, orange and red can be absorbed by the plant, to a lesser or greater degree.</em>
Answer:
yes it is a chemical change
Explanation:
because first it was in liquid and turned into gas
Answer: Option (a) is the correct answer.
Explanation:
A chair is a solid substance and it is known that particles in a solid are closely held together by strong intermolecular forces of attraction.
Therefore, solids are rigid and have a definite shape.
Thus, we can conclude that the chair in which you are currently sitting retain its same shape over time because the particles of the chair are strongly held together.
Answer:
The energy needed to split an atom into separate protons, neutrons, and electrons
Explanation:
The equation E = MC^2 is developed by Einstein’s Special Relativity Theory
where,
E = Energy
M = mass
C = speed of the light
The energy should be measured in Joules i.e J
The mass should be measured in Kilogram i.e Kg
And, the speed of the light should be measured in meters per second i.e ms-1
The C should be squared
Now the energy is required to divided into three particles i.e protons, electrons and neutrons
It also needs to allocate the nucleus into distinct protons and neutrons that we called binding energy of nuclear
And if the energy is required to take off an electron from an atom we called the energy of ionization
And if the energy is required to add an electron to an atom so we called it affinity of electron
