Answer:

Combination or synthesis

Explanation:

The chemical reaction is given as:

        2N₂   +   O₂   →   2N₂O

From the reaction above we see that this is a combination reaction. In a combination reaction, two or more species combines to give a product.

  • The formation of compounds from the union of their constituent elements falls into this category of reaction.

This combination reaction is also known as a synthesis reaction.

A 0.5 mol sample of N2 is in a 6L container at 2 atm. what is the temperature of the gas in K
Andreas93 [3]

Answer:

300 K

General Formulas and Concepts:

<u>Atomic Structure</u>

  • Diatomic Elements
  • Moles

<u>Gas Laws</u>

Ideal Gas Law: PV = nRT

  • <em>P</em> is pressure
  • <em>V</em> is volume
  • <em>n</em> is moles
  • <em>R</em> is gas constant
  • <em>T</em> is temperature

Explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

[Given] <em>n</em> = 0.5 mol N₂

[Given] <em>V</em> = 6 L

[Given] <em>P</em> = 2 atm

[Given] <em>R</em> = 0.0821 L · atm · mol⁻¹ · K⁻¹

[Solve] <em>T</em>

<em />

<u>Step 2: Solve for </u><em><u>T</u></em>

  1. Substitute in variables [Ideal Gas Law]:                                                          (2 atm)(6 L) = (0.5 mol)(0.0821 L · atm · mol⁻¹ · K⁻¹)T
  2. Multiply [Cancel out units]:                                                                               12 atm · L = (0.04105 L · atm · K⁻¹)T
  3. Isolate <em>T</em> [Cancel out units]:                                                                             292.326 K = T
  4. Rewrite:                                                                                                             T = 292.326 K

<u>Step 3: Check</u>

<em>Follow sig fig rules and round. We are given 1 sig fig as our lowest.</em>

292.326 K ≈ 300 K

Which of the following is an example of a model? PV=nRT, Geographical map, I believe that aliens exist, all of the above.
aleksandrvk [35]

<u>Answer:</u> The correct answer is geographical map.

<u>Explanation:</u>

Model is defined as the three dimensional representation of a proposed structure in a smaller scale.

For the given options:

<u>Option 1:</u>  PV = nRT

This is a proposed law. This law is known as ideal gas law. A law is defined as the rule which defined a correct procedure. For any gas behaving ideally, this law is used.

<u>Option 2:</u> Geographical map

Map is defined as the diagrammatic representation of an area of land or sea which also shows physical features, roads, cities etc..

A 3-D model can be prepared for geographical map.

<u>Option 3:</u> I believe that aliens exist

This is a hypothetical statement. It is a smart guess by the means of set of assumptions and observations. For its validation, we need to conduct some experiments.

Hence, the correct answer is geographical map.
