Answer:

angle of reflection: B

angle of refraction: E

normal line: G

incident ray: H

boundary: I

Explanation:

When a wave incidents on a boundary, some of it bounces back and some transmits and refracts. From the laws of reflection we know that angle of incidence is equal to angle of reflection. The incident ray, the reflected ray and the normal all lie in same plane. From Snell's law, the angle of refraction differs from angle of incidence as the wave travels from one medium to another.

In the given diagram,

H represents the<u> incident ray. </u>

I represents the <u>boundary.</u>

G represents the <u>normal</u>.

<u>Angle of incidence </u>is given by A.

<u>Angle of reflection </u>is given by B.

<u>Angle of refraction</u> by E.

F represents the <u>refracted ray.</u>

Ok,

The angle of reflection is D as the ray is bounced off the mirror.
The angle of refraction is E since the ray is refracted and changes speed.
The normal line is G.
The incident ray is H.
The boundary is I.

Hope this helps :).

What is the total energy required to break all the bonds in 1 mol propanol,<br> C3H8O?
USPshnik [31]

Answer:

The total energy to break all the bonds in 1 mole of 1-propanol, C₃H₈O, is 4411 kJ/mol

Explanation:

We note that propanol, C₃H₈O is also known as 1-propanol is written as follows;

CH₃CH₂CH₂OH which gives

CH₃-CH₂-CH₂-OH

Hence, the total number of bonds are;

C-H Bonds = 3 + 2 + 2 = 7

C-O Bonds = 1

O-H Bond = 1

C-C Bonds = 2

The bond energies are as follows;

C-H Bonds = 413 kJ/mol

C-O Bonds = 358 kJ/mol

O-H Bond = 468 kJ/mol

C-C Bonds = 347 kJ/mol

Energy required to break the bonds in 1-propanol is therefore;

C-H Bonds = 413 kJ/mol × 7 = 2,891 kJ/mol

C-O Bonds = 358 kJ/mol × 1 = 358 kJ/mol

O-H Bond = 468 kJ/mol × 1 = 468 kJ/mol

C-C Bonds = 347 kJ/mol × 2 = 694 kJ/mol

The total energy to break all the bonds in 1 mole of 1-propanol = 4411 kJ/mol.

Which is the most likely to be reduced?
NISA [10]

Answer : The correct option is, Zn^{2+}

Explanation :

  • Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.

Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.

  • Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.

Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.

According to the electrochemical series, Zn^{2+} most likely to be reduced because

Hence, the ion most likely to be reduced is Zn^{2+}.
