Answer: The options are not given, here are the options.
A)There is an indirect relationship: as thermal energy increases, there is more particle movement.
B) There is an indirect relationship: as thermal energy increases, there is less particle movement.
c) There is a direct relationship: as thermal energy increases, there is more particle movement.*****
d) There is a direct relationship: as thermal energy increases, there is less particle movement.
The correct option is C.
There is a direct relationship: as thermal energy increases, there is more particle movement.*****
Explanation:
There is a direct relationship: as thermal energy increases, there is more particle movement because when there is increase in thermal energy or heat in a substance, the particles start to vibrate and move faster as a result of the particles gaining kinetic energy which is as a result of increased collision and diffussion rates.
As they vibrate the space between the particles increases which result in increase in motion or movement of the particle
A student in a chemistry class mixes together two chemicals and observes bubbling and the beaker getting hotter. There was also a dark blue precipitate settling down to the bottom of the beaker. Did a new substance form during the investigation?
Explanation:
Obviously there's an exothermic reaction going on, which suggests a neutralisation reaction. A dark blue precipitate is formed, which could be a copper salt. So a new substance formed.
There is undoubtedly an exothermic reaction occurring, which denotes a neutralization reaction. A dark blue precipitate that could be a copper salt forms. Thus, a new material developed.
Why does the pace of a reaction increase as temperature rises?The average kinetic energy of the molecules rises as the reactants heat up. This indicates that more molecules are traveling more quickly and colliding more forcefully. The pace of the reaction rises as more molecules collide with one another with sufficient energy to cause a reaction.
Usually, a reaction's rate increases as temperature rises. As a result, a higher percentage of molecules will possess the minimal amount of energy required for a successful collision.
Endothermic reactions occur when two substances interact and the temperature of the resulting mixture drops.

Water is being pumped out of a reservoir at a rate of 2.54 liters per 15.0 seconds. If the reservoir contains 1.0500 x 106 gallons of water, how many hours will it take to empty it?
Answer:
It will take 6,519.44 hours to empty the reservoir.
Explanation:
First of all, you should know that 1 gallon = 3.785 L
So, you can apply the following rule of three to know the amount of water in liters in the reservoir: if 1 gallon is 3.785 liters, 1.0500 * 10⁶ gallons of water, how many liters are they?
[tex]amount=\frac{1.0500*10^{6} gallons*3.785 liters}{1 gallon}[/tex]
amount= 3,974,250 liters
Knowing that water is pumped out of a reservoir at a rate of 2.54 liters every 15.0 seconds, you now want to pump 3,974,250 liters of water out of the reservoir. For that you apply the following rule of three: if 2.54 liters are pumped out every 15 seconds, how long does 3,974,250 liters take to be pumped out?
[tex]time=\frac{3,974,250 liters*15 seconds}{2.54 liters}[/tex]
time= 23,469,980.32 seconds
With 1 hour 60 minutes and 1 minute equal to 60 seconds, then 1 hour represents 3,600 seconds. So you apply the following rule of three: if 3,600 seconds is 1 hour, 23,469,980.32 seconds, how many hours are they?
[tex]time=\frac{23,469,980.32 seconds*1 hour}{3600 seconds}[/tex]
time=6,519.44 hours
It will take 6,519.44 hours to empty the reservoir.
a balance reads an object A to be 45.1kg the balance reads another object B to be 33.46kg what is the total weight of both objects
All we need to do is add.
45.1 + 33.46 = 1509.046
Therefore, the total weight of both objects is 1,509.046kg

Your answer should indicate the proper precision (correct number of insignificant figures).
1. 1,010 L
2. 1,007.0 L
3. 1,007 L
4. 1,000 L
Answer:
The sum of given measurements is 1007 L.
Explanation:
The given measurements are 28 L, 42 L, 6 L, and 931 L.
We need to find the total of these measurements.
Total = 28 L + 42 L + 6 L + 931 L
It can be written as
Total = ( 28 +42+6+931)
One simplification we get Total = 1007 L
A student lists three temperature measurements: 100°F, 100°C, and 100 K. Of the three measurements, 100 K is the highest temperature.a. Trueb. False
Answer:
The answer is False.
Explanation:
To find which is the highest temperature we need to convert the °C and °F units to °C:
[tex] T_{1} = 100 K [/tex]
[tex] T_{2} = 100 ^{\circ} C + 273 = 373 K [/tex]
[tex] T_{3} = \frac{5}{9}*(100 ^{\circ} F - 32) = 37.78 ^{\circ} C [/tex]
[tex] T_{3} = 37.78 ^{\circ} C + 273 = 310.78 K [/tex]
Therefore, the answer is False, since the highest temperature is 100 °C.

What NaClNaCl concentration results when 259 mL259 mL of a 0.850 M0.850 M NaClNaCl solution is mixed with 567 mL567 mL of a 0.240 M0.240 M NaClNaCl solution?
Answer:
0.431M
Explanation:
To find the concentration of NaCl we need to know how many moles comes from each solution. Then, we need to sum the total volume in liters and, as molarity (Unit of concentration) is the ratio between moles and volume we can determine concentration.
Moles from first solution:
259mL = 0.259L * (0.850mol / L) = 0.22015 moles of NaCl
Moles from second solution:
567mL = 0.567L * (0.240mol / L) = 0.13608 moles of NaCl
Total moles:
0.22015 + 0.13608 = 0.35623 moles of NaCl
Total volume:
259mL + 567mL = 826mL = 0.826L
Thus, molarity of the mixture is:
0.3562 moles NaCl / 0.826
0.431M

why scientists use the word dominant
Answer:
Dominant traits are traits that more likely to be transferred from a parent to an offspring so scientist use this term dominant.
Answer:
Scientists use the word dominant for certain traits because they are more likely to show up. There are two different types of alleles for traits: dominant and recessive. Capital letters mean dominant and lowercase mean recessive. Scientists also use the word dominant for certain traits when certain traits stand out and are more prone to show up in offspring.
