The answer to this question would be: 2; 3; 3

In nitrogen gas structure, there are 5 total electron pairs which were made by 2.5 electron pairs(5 electrons) for every nitrogen atom. In the middle, you will found 3 pair making bond order 3. In each nitrogen, there will be 1 nonbonding electron making it a total 2 unbonding electron pairs.

Which two solutions would be the BEST choice for their experiment?
Margaret [11]

Solutions 1 and 3 because they are strong acids and a strong base. <u>Option A.</u>

<u />

Strong acids and strong bases are completely ionized in an aqueous solution. Weak acids and weak bases also ionize, but only partially and the reaction is reversible. So you know if an acid or base is strong or weak. A simple way to determine strength is to add the acid or base to water. A higher reactivity means a stronger acid or base.

One of the simplest tests to determine whether a solution is an acid or base is the litmus paper test. To do this, dip a special strip of paper so-called litmus paper into the solution and observe the color of the paper. Litmus paper turns red in acidic solutions and blue in basic solutions. Sodium hydroxide is the strongest base because it completely dissociates to form sodium and hydroxide ions. These hydroxide ions are further treated with hydrogen ions by an acid to completely ionize the hydrogen ions.

an element "x" has the election configuration 2,8,3 this element is found in ______group and_____period A.3,llla B.llla,3 C.vlla
iogann1982 [59]

This element is found in group 3A, period 3

<h3>Further explanation </h3>

The maximum number of electrons that can be filled in the nth electron shell is 2n²(n=shell)

  • K shell (n = 1) maximum 2 x 1² = 2 electrons
  • L shell (n = 2) maximum 2 x 2² = 8 electrons
  • M shell (n = 3) maximum 2 x 3² = 18 electrons
  • N shell (n = 4) maximum 2 x 4² = 32 electrons

Electron configuration of element X : 2.8.3 , so :

K shell = 2 ⇒1s²

L shell = 8⇒2s²2p⁶

M shell = 3⇒ 3s²3p¹

Block p: group 13-18 (has a 2p-6p configuration), also called a representative element because it includes metals, non-metals and metalloids

The outer shell 3s²3p¹ : located in group 3A and period 3

group⇒valence electron ⇒3

period⇒the greatest value of the quantum number n⇒3

A graduated cylinder initially contained 11 mL of water and then an 8 g block of wood is put into it, changing the volume to 15
Paul [167]

Answer:

Density is 2

Explanation:

Do the final volume of water divided by the inital

volume of water to get 4

15-11 = 4

Volume = 2

Mass = 8

Then to the equation m/v

8/4 = 2

Density = 2

Give the IUPAC name for<br> Spell out the full IUPAC name of the compound.
Soloha48 [4]

Explanation:

Part A

Spell out the full name of the compound.

Part B

Spell out the full name of the compound.

Part C

Spell out the full name of the compound.

Part D

Spell out the full name of the compound.

IUPAC naming:

In organic chemistry, chemical compounds are named by a standardized method known as the IUPAC system. These four examples are all hydrocarbons with double and triple bonds. The names of the compounds are based on the length of the carbon chain, the position of the double or triple bonds and the position of any carbon groups branched off of the main chain.
