Which term is defined as a measure of the disorder of a system? (A) heat (B) kinetic energy (C) entropy (D) activation energy

Answers

Answer 1

Answer: The question is asking which of the following choices is defined as a measure of the disorder of a system, and base on the question and further research of the said question, I would say that the answer would be C. Entropy. I hope you are satisfied with my answer and feel free to ask for more

Answer 2

Answer:

Answer:

C. Entropy

Explanation:

Heat is defined as the energy transferred from a hotter to a cooler body.

Kinetic energy is defined as the energy of a body in motion.

Entropy is a thermodynamic quantity that could be defined as a mesure of the disorder of a system. For a ordered crystal, entropy is zero.

Activation energy is defined as the minimum quantity of energy required to activate a particular chemical process.

I hope it helps!

Energy + 6CO2 + 6H2O → 6O2 + C6H12O6 The purpose of photosynthesis is to produce usable chemical energy or glucose from solar energy. If the formula for glucose is C6H12O6, how many atoms of carbon are used to produce the glucose?A) 1

B) 2

C) 6

D) 9

Answers

Answer:

The answer is c) 6

Explanation:

In the expression of the reaction

Energy + 6CO2 + 6H2O → 6O2 + C6H12O6

you can see that to produce a mol of glucose (C6H12O6) you need 6 moles of CO2, which it is the reagent that contains the atom of carbon used to produce glucose. Now you multiply the coefficient 6 by the subscript 1, which is the amount of carbon atoms that the molecule CO2 contains. So you end up with 6 atoms of carbon.

C stands for carbon atoms. In glucose thera are 6 carbon atoms, so 6 carbon atoms are used to produce glucose.

Answer: C) 6

What is the molarity of 1.5 liters of an aqueous solution that contains 52 grams of lithium fluoride, LiF, (gram-formula mass =26 grams/mole)?(1) 1.3 M (3) 3.0 M
(2) 2.0 M (4) 0.75 M

Answers

The answer is (1) 1.3 M. The first thing you need to do is to convert the unit of gram to mole. The mol number of LiF is 52/26=2 mol. Then using the volume to calculate the molarity: molarity=2/1.5=1.3 M.

Biotechnology can be both useful and potentially destructive. Choose one example of biotechnology and identify whether it has had a positive or negative effect on society. Explain your answer.

Answers

I am not going to give you a full research report, but one example is DNA fingerprinting via gel electrophoresis. This has definitely had a positive effect on society, as it makes forensics a much more certain and just process. Gel electrophoresis can be used to separate and arrange DNA strands in order of length. You can then compare this arrangement to determine whether or not it matches another DNA arrangement. It has a very high accuracy rating, so you can be almost certain that if you have two electrophoresis results that look identical, that both DNA samples belong to the same person. This is compelling evidence that can either acquit or condemn suspects with certainty.

What happens to the average kinetic energy of the water molecules in your body when you have a fever?

Answers

When you have a fever, the average kinetic energy of the water molecules in your body increases because the molecule's speed increases.

What is kinetic energy?

In physics, kinetic energy is the energy that an object has as a result of motion. It is defined as the amount of effort required to move a mass-determined body from rest to the specified velocity.

Unless the body's speedchanges, the kinetic energy gained during acceleration is retained.

Kinetic energy is the energy that an object has as a result of motion. To accelerate an object, a force must be applied to it.

We must exert effort in order to use force. When the work is completed, energy is transferred to the item, which moves at a new, constant speed.
