You start with a container that is 8L big and the temperature in the room is 326K.
If the you take the container out in the heat at 352K, how big will it get?

Answers

Answer:

The new volume is 8.64 L.

Explanation:

Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure. For a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Being an initial state 1 that modifies its conditions until a final state 2, it is fulfilled:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case:

V1= 8 LT1= 326 KV2= ?T2= 352 K

Replacing:

[tex]\frac{8L}{326 K} =\frac{V2}{352 K}[/tex]

Solving:

[tex]V2=352 K*\frac{8L}{326 K}[/tex]

V2= 8.64 L

The new volume is 8.64 L.

Savvas Realize. Investigation 8 Experiment 1

Answers

Answer:

–1065.25 KJ of energy.

Explanation:

From the question given above, the following data were obtained:

4FeO + O₂ —> 2Fe₂O₃  ΔH = –560.66 kJ

From the balanced equation above,

The formation of 2 moles of Fe₂O₃ released –560.66 kJ of energy.

Finally, we shall determine the amount of heat energy released when 3.8 moles of Fe₂O₃ are produced. This can be obtained as follow:

From the balanced equation above,

The formation of 2 moles of Fe₂O₃ released –560.66 kJ of energy.

Therefore, the formation of 3.8 moles of Fe₂O₃ will release

= (3.8 × –560.66)/2 = –1065.25 KJ of energy.

Thus, –1065.25 KJ of energy is released from the reaction.

Ammonia (NH3) is widely used as a fertilizer and in many household cleaners. How much ammonia is produced when 5.81 mol of hydrogen gas react with an excess of nitrogen gas?

Answers

Answer:

65.841 g

Explanation:

The balanced equation for this reaction is;

N2 + 3H2 → 2NH3  

From the question, we are interested in ammonia and the hydrogen gas.

From the equation

3 mol of H2 produces 2 mol of NH3

5.81 mol would produce x

Solving of x;

x = 5.81 * 2 / 3

x = 3.873 mol

Converting to mass;

Mass = Number of moles * molar mass

Mass =  3.873 * 17 = 65.841 g

A drug company is testing the effects of a new drug designed to prevent hair loss. Of the 2,000 people in the trial, 1,700 people receive the drug and the other 30 people receive a sugar pill. What is the purpose of the group receiving the sugar pill? A. The group is being used as the control group B. The group is being used as the dependent variable C. The group is being used as the independent variable D. The group is being used as the manipulated variable

Answers

Answer:

A

Explanation:

The correct answer would be that the group being given the sugar pill is being used as the control group.

In a typical experimental study, there are two groups of subjects:

1. The treatment or the experimental group

2. The control group

The treatment group receives the treatment variable while the control group does not receive or is given a placebo. Thus, the control group act as the reference group for comparison basis. Any difference in the observation between the two groups would be attributed to the treatment variable.

The correct option is, therefore, A.

Which statement explains these properties?.

Answers

Answer:

C. It has no delocalised electrons and each carbon atom forms four covalent bonds with other carbon atoms.

Explanation:

Diamond is composed solely by carbon atoms. As the difference of electronegativity between atoms is 0, diamond is a fully covalent compound.The lack of electrical conductivity stems from a lack of available electrons, this means that there are no delocalised electrons.

The information in the first point discards options A and D, while the second point discards option B. Thus the answer is option C.
