Which of the following shows a correct Lewis dot structure

Chemistry
2 answers:
GarryVolchara [31]3 years ago
7 0

Answer:

The correct Lewis structure is D)

Explanation:

The Lewis structure always has to represent the electrons of the most external level of the atom, also called valence electrons. These electrons will be involved in an eventual chemical reaction.

In this case the only correct answer is the structure of N which has 5 electrons on its most external level.

Consider a 100-gram sample of radioactive cobalt-60.
svetlana [45]

It will take 5.2 years to decay.

The half life of cobalt-60 is 5.2 years. The half life is the time taken for the mass of the substance to decrease by a half.

here, the amount of remaining substance is 50%,

so, (\frac{1}{2} )^{n} = 0.5

n. log (0.5) = log (0.5)

n = 1

So it would take 1 half lives to decay this much, which is 1 x 5.2 which is 5.2 years.

what do you mean by radioactive decay ?

The process through which an unstable atomic nucleus loses energy via radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A material that has unstable nuclei is considered as radioactive.

Directions: Use the words in the word box to complete the following sentences.
NeX [460]

Explanation:

When the forces acting on an object are balanced , there is no change in the object's motion.

A force acting on a resting object can cause the object to move.

On Earth, gravity pulls all objects toward the ground.

When a force acts in the opposite direction of another force, the forces counteract each other.

More than one force acting on a falling object can reduce its downward acceleration

Air resistance is caused by molecules of air pushing against a moving object

What is the correct chemical equation for the reaction between methane and oxygen to produce carbon dioxide and water?
kodGreya [7K]

Answer:

The answer to your question is:   CH₄     +    3/2 O₂     ⇒     CO₂    +   2 H₂O

Explanation:

Methane = CH₄

Oxygen = O

Carbon dioxide = CO₂

Water = H₂O

                      CH₄     +    3/2 O₂     ⇒     CO₂    +   2 H₂O

        This is the balanced equation
