How is carbon monoxide formed in a combustion reaction and what is it?

Answers

Answer 1
Answer:

Answer:

Carbon monoxide is produced when combustion reactions are not fully completed,either through lack of oxygen or due to low mixing.

Carbon monoxide is a colorless and odorless gas.

explain how a mutation in an individual's DNA occurs, and describe the effect it may have on the individual's traits.

Answers

A mutation in the DNA ca happen during growth, when the DNA splits and becomes RNA. Mutations can also occur from other invasive cells, such as bacteria or viruses. A mutation in your DNA can also be there from when you were born. These mutations can cause variations in your appearance, such as eye color, ability to see, taste, smell and the complexion of your face. The mutations can also result in variations in your growth, causing immature or late growth. These mutations are dangerous, and can result in failure of the organisms cells , to complete and utter death of an organism.

Answer:

DNA are transcribed to the aRNA and then, in turn, morphed by the tRNA, altering the protein acid chain and keeping the function of the protein, which affects the traits of the individual.

Which has more kinetic energy, a feather floating through the air or a rock on the ground? Explain.

Answers

Well, it would be the feather floating through the air, as the feather is moving and because of it it possess kinetic energy because of its motion. A rock on the ground has no kinetic energy as it is not moving.

Final answer:

The rock on the ground has more kinetic energy compared to the feather floating through the air, due to the force of gravity.

Explanation:

Kinetic energy is the energy of motion, and a moving object has kinetic energy. Potential energy, on the other hand, comes in several forms, such as gravitational potential energy. When comparing a feather floating through the air and a rock on the ground, we can say that the rock has more kinetic energy.

This is because the rock, when dropped, falls to the ground due to the force of gravity, gaining kinetic energy in the process. The feather, on the other hand, is floating through the air and not experiencing the same gravitational pull, thus having less kinetic energy than the rock.

PLEASE HELP!!!!!!suppose that mA is 8.1 kg and mBis 6.5kg. The distance between their centers is 0.5o m.Calculate the force of attraction between these two bodies?

Answers



Somewhere in your book or your notes, you must have met the formula for the
gravitational attraction between two bodies.  If you can go back and find it, you
only need to plug your numbers into that formula, and out will pop the answer.

Formula:                            Force = G (mA x mB) / (distance)²

If everything is in SI units, then        G = 6.67 x10⁻¹¹ newton-meter² / kilogram²

You said that
                         mA = 8.1 kg
                         mB = 6.5 kg
                 distance = 0.5 m .

   Force = (6.67 x 10⁻¹¹ nt-m²/kg²) (8.1kg x 6.5kg / (0.5m)² =

                (6.67 x 10⁻¹¹ nt-m²/kg²)    ( 52.65 kg² ) / (0.25 m²) =

                     1.4047 x 10⁻⁸ newtons .

That's roughly    5.052 x 10⁻⁸ ounce .  (5% of one micro-ounce)
