Pelase answer the question in the picture
olchik [2.2K]

Answer:

B

Step-by-step explanation:

Notice that the equation shows KNO_3 going from a solid to an aqueous solution, which is dissolved. Entropy is essentially when a system becomes more disordered. Whenever we go from solid to liquid to gas, that's becoming more disordered because the molecules in the system are moving much more and in more random directions.

In addition, when we dissolve solids into water, that's another increase in entropy because we technically have a liquid component here and the molecules are now breaking apart.

So, the entropy here will increase.

Hope this helps!

Find an explicit formula for the geometric sequence -1,-7,-49,-343,.... Note : the first term should be d(1) . d(n) =
n200080 [17]

Answer:

<h3>dn = -7^n-1</h3>

Step-by-step explanation:

Given the sequence -1,-7,-49,-343,....

We are to find the nth term of the sequence

dn = ar^n-1

a is the first term = -1

r is the common ration = -7/-1 = -49/-7 = 7

n is the number of terms

Substitute

dn = -1(7)^n-1

dn = -7^n-1

hence the nth term of the sequence is dn = -7^n-1

8.4.9 On or off the line &amp; Practice Problems
Andrews [41]

Answer:

Number of quarters → 15

Number of dimes → 2

Step-by-step explanation:

Let the number of dimes I have = y

And number of quarters = x

Since, I have amount in my pocket = $2

Therefore, 0.10y + 0.25x = 2

100(0.10y + 0.25x) = 100×2

25x + 10y = 200

5x + 2y = 40

2y = -5x + 40

y = -2.5x + 20 ---------(1)

Total number of coins in my pocket = 17

x + y = 17

y = -x + 17 ---------(2)  

By using a graphing calculator we can graph these two lines (As attached)

Solution of the given system of equations will be the point of intersection of these lines.

Solution → (2, 15)

Number of quarters → 15

Number of dimes → 2
