A student made a sketch of a potential energy diagram to represent an exothermic reaction.

Mathematics

This diagram is incorrect because in an exothermic reaction, the amount of potential energy in of the reactants is higher than that of the products because energy is being released. In this diagram, the potential energy of the products is higher than the reactants, which would represent an endothermic reaction because energy is being absorbed. If you simply look up exothermic reactions and endothermic reactions, you can view countless images of digrams that show this.

Answer:

This is not correct

Step-by-step explanation: I am just a 6th grader but i know this question, it is not correct because potential energy is mostly staying in one place this would be kenetic energy because it is moving.

Answer:

a° = 58°

b° = 48°

c = 74°

d° = 122°

Step-by-step explanation:

<em>Angles on a straight line add up to 180°</em>

58° + d° = 180°

d° = 180° - 58° = 122°

<em>Alternate angles are equal.</em>

a° = 58°

<em>Angles in a triangle add up to 180°.</em>

48° + 58° + c° = 180°

106° + c° = 180°

c° = 180° - 106° = 74°

<em>Angles on a straight line add up to 180°</em>

74° + 58° + b° = 180°

132° + b° = 180°

b° = 180° - 132° = 48°

Mindy left at 8 a.M. And will arrive at 1 p.M.; jelly left at 8 a.M. And will arrive at 2 p.M. How many miles is the trip if Kel
uysha [10]

Answer:

300 miles

Step-by-step explanation:

The distance equation is D = RT

Where

D is the distance

R is the rate

T is the time

<u>Mindy</u>

8 am to 1 pm = 5 hours

<u>Kelly</u>

8 am to 2 pm = 6 hours

Kelly's rate is 10 mph SLOWER than mindy, so if we let Mindy's rate be "m", so Kelly's rate will be " m - 10 "

Now using the distance equation, we can write:

Mindy >>> D = RT >>> D = 5m

Kelly >>> D = RT >>>  D = 6(m-10) >>> D = 6m - 60

Since both the distances are equal, we can write:

5m = 6m - 60

m = 60

We want the distance, we know:

D = 5m

D = 5(60)

D = 300 miles

The distance is 300 miles
