Answer:
See explaination for details and diagram
Explanation:
We can say that Chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds.
A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
See attachment for the buffer of the chemical reaction.
<u>Answer:</u> The spacing between the crystal planes is 
<u>Explanation:</u>
To calculate the spacing between the crystal planes, we use the equation given by Bragg, which is:

where,
n = order of diffraction = 2
= wavelength of the light =
(Conversion factor:
)
d = spacing between the crystal planes = ?
= angle of diffraction = 22.20°
Putting values in above equation, we get:

Hence, the spacing between the crystal planes is 
Answer:
C10H200
Explanation:
The molecular formula C10H20O (molar mass : 156.27 g/mol) may refer to: Citronellol. Decanal.
The answer is D higher potential energy and is unstable
1. Energy as particles can't move without kinetic (movement) energy
2. I think it's Diffusion and Active Transport
