Draw the lewis structure of hcn. include lone pairs.
Rina8888 [55]

The Lewis structure of the hydrogen cyanide molecule is represented by the image shown.

<h3>What is the Lewis structure?</h3>

We know that the Lewis structure is showing us the relationship between the electrons pairs in the compound and its overall properties. The Lewis structure consists of the symbol of the element and the electrons pairs that surround the atom.

We can see that in hydrogen cyanide there is a nitrogen atom and there is a hydrogn atom and also one carbon atom. The bond between carbon and nitrogen is covalent while the bond between hydrogen and the cyanide moiety is covalent.

P * V = n R T 
<span>1 * 2.50 = n * 0.082 * 273 = 2. 50 / ( 0.082 * 273 ) = 0.11 mol </span>
<span>mass = mole number * molecular mass </span>
<span>mass = 0.11 * ( 16 * 2 ) = 3.52 g </span>

The diagram shows monochromatic light passing through
Maru [420]

Destructive interference in which waves cancel each  other out is depicted in region X,Y and Z.

<u>Explanation:</u>

Interface is the particle property of light waves. When incident light beam is made to pass through holes, the waves will combine either constructively or destructively. Constructive interference means the waves having same phase will get added so they will increase in amplitude. While destructive interference means the waves combining have different phases like crests and troughs. So they undergo decrease or complete vanishing of amplitude.

When waves combine in constructive interference, they form bright white light and when they combine in destructive interference, they form dark black light. So the regions X, Y and Z are shown as dark black colors in the diagram, so these regions represent destructive interference in which waves cancel each  other out.

How many major reservoirs does carbon move between?<br> A. 3<br> B. 4<br> C. 5<br> D. 2
Irina-Kira [14]
<span>Carbon can also bond with other four atoms because of its outer shell (valence shell) that has four electrons. This is the reason why organic molecules can be so large because of this bonding. Suppose you have a compound of CCl4. You know that chlorine can only share 1 electron because 7 of its electrons are filled. Also, in carbon, it can only share 4 electrons because 4 of it are already filled. That is why carbon needs four chlorine to form CCl4. The answer is letter <u>B.</u></span>
