Answer:
a) ◇G = ◇H - T◇S wiĺl be negative.
b) It will be a spontaneous reaction.
Explanation:
As ◇H is less than 0 and T◇S is greater than 0 so if we put it in the equation we would get the negative maximum result. And when the energies are with negative sign they are said to be spontaneous.
Answer:
Equation of line shown in the graph is : x= - 2
Step-by-step explanation:
Given,
a line passing through two points ( -2,2) and ( -2,-3).
We need to use two pint line equation:
y - y1 = (y2 - y1 / x2 - x1 ) (x - x1 )
Here , x1 = -2 ,x2 = -2 , y1 = 2 and y2 = -3
So we can plug corresponding values in the line equation.
We get: y - 2 = {(-3 - 2) / ( -2 - (-2))} (x - (-2))
y - 2 = (-5 /0 ) (x + 2)
0 * (y - 2) = -5 (x+2)
0 = -5x - 10
10 = -5x
x = -10/5 = -2
Hence x= -2 is the equation of line shown in the graph.
Step-by-step explanation:
10 -3 10+3*-3= 12 x=10-8=6
Answer:
The length of legs lm, mn, and lk is 32 while that of kn is 36.
Step-by-step explanation:
The diagram is attached in the answer.
As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk
This leads the two set of legs such as

Or this could be written as

Now the remaining two sides are given as
as this form an isosceles triangle so

Similarly

Or

Now the perimeter is given as

Here perimeter is given as 132 so this gives:

So the four legs are of length as given below:

So the length of legs lm, mn, and lk is 32 while that of kn is 36.
Answer:
The shaded area is 
Step-by-step explanation:
we know that
The shaded area is equal to the area of the large square minus the area of the two smaller squares
so

Calculate the shaded area
Remember that

substitute
