2. How many moles are in 2.8 Liters of CO2 gas?

Answers

Answer:

0.125 moles

Explanation:

2.8 litres is equivalent to 2.8dm³

At STP,

1 mole = 22.4 dm³

x mole = 2.8 dm³

Cross multiply

22.4x = 2.8

Divide both sides by 22.4

x = 2.8/22.4

x = 0.125

How does the environment in which an organism lives determine which traits are adaptations?
can someone plss help me??​

Answers

Answer:

When an organism lives in a certain environment there is a process called natural selection. Natural selection ensures that the organisms of a species with the best traits suited for an environment will reproduce and pass on those traits to the offspring.

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.

Diamond is extremely hard and does not conduct electricity.
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.

Continue reading from Ruby Bridges’s autobiography.

We drove down North Galvez Street to the point where it crosses Alvar. I remember looking out of the car as we pulled up to the Frantz school. There were barricades and people shouting and policemen everywhere. I thought maybe it was Mardi Gras, the carnival that takes place in New Orleans every year. Mardi Gras was always noisy.

As we walked through the crowd, I didn’t see any faces. I guess that’s because I wasn’t very tall and I was surrounded by the marshals. People yelled and threw things. I could see the school building, and it looked bigger and nicer than my old school. When we climbed the high steps to the front door, there were policemen in uniforms at the top. The policemen at the door and the crowd behind us made me think this was an important place.

It must be college, I thought to myself.

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.
