Part d based on your answer to part c, how many bonding electrons and lone pair electrons (nonbonding electrons) are there in th

elena55 [62]

The Lewis Structure of HCN is shown below,

Number of Bonding Electrons:
In HCN Hydrogen is bonded to Carbon through single bond and Nitrogen is bonded to Carbon through Triple Bond. Single bond is formed by two bonding electrons, while, triple bond is formed by six bonding electrons, Hence,

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons:
In HCN there is only one lone pair of electron present on Nitrogen atom which is not taking part in bonding. Hence,
Number of Non-Bonding Electrons = 2

Result:

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons = 2

Is it possible for an electron in a hydrogen atom to emit a gamma ray by falling to a lower energylevel?

jeka94

No, its not possible. Let's go back to 4th grades' basic science.
"Energy can not be created or destroyed."
This applies to everything, even atoms!

A certain drug has a half-life in the body of 4.0h. What should the interval between doses be, if the concentration of drug in t

scZoUnD [109]

Answer:

Explanation:

half life = 4 h

initial concentration = 100

final concentration = 15

Time = t

No of half life x = t / 4

15 = 100 x ( 1/2 )ˣ

.15 = ( 1/2 )ˣ

ln .15 = - x ln2

x = - ln .15 / ln 2

= 1.897 / .693

x = 2.737

x = t / 4

t = 2.737 x 4 = 11 h approx .

Which is the pathway of light as it travels through the eye?

KATRIN_1 [288]

Cornea - lens - retina

Explanation:

The pathway of light into the eyes goes from the cornea through the lens where it gets focus on the retina and optic nerves picks up the signal where the brain interprets the image. The eye is the organ of sight.

When light rays from objects hits the human eye, it goes through the cornea first. In the cornea the image begins to form and using the pupil located in it the amount of light that enters is regulated.
From the cornea, light goes into the lens. The lens allows for the rays to focus on the retina.
The retina receives the rays and the image forms .
