Not sure if this is right but this is what I think 
Thermal energy added: Particles move faster, Kinetic energy increases, Temperature increases
Thermal Energy removed: Particles move slower, Kinetic energy decreases, Temperature decreases

Explanation:

Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.

So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.

And, on decreasing thermal energy there will occur a decrease in the kinetic energy of the molecules of an object. As a result, motion of particles will slow down.

Therefore, we can conclude that the given statements are matched as follows.

Thermal energy added:

- Particles move faster.

- Temperature increases.

- Kinetic energy increases.

Thermal energy removed:

- Particles move slower.

- Temperature decreases.

- Kinetic energy decreases.

Identify ALL the possible mol ratio from<br> this balanced equation:
Karolina [17]

There are 3 possible mole ratios

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

<em>N₂(g)+3H₂(g)⇒2NH₃</em>

So mol ratio :

N₂:H₂:NH₃=1:3:2

  • Possible mol ratio :

1 mole N₂

3 mol H₂

2 mole NH₃

3 mole H₂

1 mole N₂

2 mole NH₃

Gaseous ammonia chemically reacts with oxygen o2 gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ni
Sergio [31]

Answer: 0.050 moles of nitrogen monoxide are produced by 0.050 moles of ammonia.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical reaction is:

4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+5H_2O(g)

According to stoichiometry:

4 moles of ammonia produce = 4 moles of nitrogen monoxide

Thus 0.050 moles of ammonia produce =\frac{4}{4}\times 0.050=0.050 moles of nitrogen monoxide

How much heat is required to raise the<br> temperature of 835g of water from 35.0°C to<br> 65.0°C?
Anna007 [38]

Answer:

25,050 calories.

Explanation:

A calorie is the amount of energy needed to raise the temperature of one gram of water 1 degree centigrade. If we are raising 835 grams of water 30 degrees then we multiply 835*30 to get 25,050 calories.
