Identify the reference angle es001-1. Jpg for each given angle, es001-2. Jpg. Es001-3. Jpg degrees. Es002-1. Jpg degrees. Es003-

julia-pushkina [17]

The reference angle is the smallest angle between the terminal side and the x-axis.

$(1)\ \theta = 300^o$

300 degrees is in the 4th quadrant.

So, the reference angle is

$\alpha = 360 - \theta$

$\alpha = 360 - 300$

$\alpha = 60^o$

Hence, the reference angle of 300 degrees is 60 degrees

$(2)\ \theta = 225^o$

225 degrees is in the 3rd quadrant.

So, the reference angle is

$\alpha = \theta - 180$

$\alpha = 225 - 180$

$\alpha = 45^o$

Hence, the reference angle of 225 degrees is 45 degrees

$(3)\ \theta = 480^o$

480 degrees is in the 2nd quadrant (i.e. 480 - 360 = 120)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 120$

$\alpha = 60^o$

Hence, the reference angle of 480 degrees is 60 degrees

$(2)\ \theta = -210^o$

-210 degrees is in the 2nd quadrant (i.e. 360 - 210 = 150)

So, the reference angle is

$\alpha = 180 - \theta$

$\alpha = 180 - 150$

$\alpha = 30^o$

Hence, the reference angle of -210 degrees is 30 degrees

Identify the oxidation numbers for all the elements in the reactants and products for 2mno4−(aq)+3s2−(aq)+4h2o(l)→3s(s)+2mno2(s)

Sidana [21]

The oxidation number if eah of the elements is as follows;

Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
Oxidation number if hydrogen is +1 on both sides
The oxidation number of oxygen is -2 on both sides
The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.

<h3>What is a redox reaction?</h3>

A redox reaction is one in which there is a change in the oxidation number of the reactants from left to right.

Let us now consider the oxidation number of each element from left to right;

Oxidation number of Mn is + 7 on the right hand side and +4 on the right hand side
Oxidation number if hydrogen is +1 on both sides
The oxidation number of oxygen is -2 on both sides
The oxidation number of sulfur is -2 on the lefthand side and zero on the right hand side.
