Many free radicals combine to form molecules that do not contain any unpaired electrons. The driving force for the radical–radic

al combination reaction is the formation of a new electron‑pair bond. Consider the chemical equation. N ( g ) + NO ( g ) ⟶ NNO ( g ) Write Lewis formulas for the reactant and product species in the chemical equation. Include nonbonding electrons.

Answer:

The attached figure is the Lewis structure for the reaction.

Explanation:

The Lewis structure is a structure of the molecule in which valence electrons are represented as points that are located between the atoms that are linked, such that a pair of points means a simple covalent bond (line). The points representing non-bond electrons are placed adjacent to the atoms to which they are associated.

Debora [2.8K]

The complete balanced chemical equation is: 
4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (g) 

In statement form: 4mol NH3 reacts with 5 mol O2 to produce 6 mol H2O 

First let us find for the limiting reactant: 
>molar mass NH3 = 17 g/mol 
moles NH3 = 54/17 = 3.18 mol NH3 
This will react with 3.18*5/4 = 3.97 mol O2 

>molar mass O2 = 32g/mol 
moles O2 = 54/32 = 1.69 mol O2 
We have insufficient O2 therefore this is the limiting reactant 

From the balanced equation: 
For every 5.0 mol O2, we get 6.0 mol H2O, therefore

moles H2O formed =  1.69 mol O2  * 6/5 = 2.025 mol
Molar mass H2O = 18g/mol 
<span>mass H2O formed = 2.025*18 = 36.45 grams H2O produced</span>

The main purpose of following the course of a reaction by TLC is to: Group of answer choices Determine if all the starting mater
kakasveta [241]

Determine if all the starting material is converted to the product.

<h3>What is TLC?</h3>

Because it can provide immediate and important information about a sample's purity and whether or not a reaction is still ongoing, TLC is a common technique in the organic chemistry lab. A TLC plate can be finished in less than 5 minutes when low polarity solvents are used.

<h3>Uses of TLC:-</h3>

TLC is a chromatographic method used to separate mixtures that are not volatile.

Thin-layer chromatography can be used to:-

  • Assess a substance's purity.
  • Identify the compounds present in a particular combination.
  • Track the development of a reaction.

3.95 g of sugar (C6H12O6) is dissolved in water to make 158 mL of solution. Find the molarity.
12345 [234]

Answer:

[C₆H₁₂O₆] = 0.139 M

Explanation:

Molarity si defined as a sort of concentration. It indicates the moles of solute that are contained in 1 L of solution.

We can also say, that molarity are the mmoles of solute contained in 1 mL of solution.

For this case, the solute is sugar (glucose). Let's determine M (mmol/mL)

(3.95 g . 1mol / 180g) . (1000 mmol / 1mol) / 158 mL

We determine moles, we convert them to mmoles, we divide by mL

M = 0.139 M

Moles = 3.95 g . 1mol / 180g → 0.0219 mol

We convert mL to L → 158 mL . 1L/1000mL = 0.158L

M = 0.0219 mol / 0.158L = 0.139 M

At a consent tempture the pressure on a 2.5 l ballon is increased from 2.4 atm to 5.8 atm. what is the new volume?
marissa [1.9K]

Answer:

1.034 L

Explanation:

P1 V1 = P2 V2

P1 V1 / P2 = V2

2.4 (2.5) / 5.8 = V2 = 1.034 L
