Answer:

183 K

General Formulas and Concepts:

<u>Chemistry - Gas Laws</u>

Combined Gas Law: PV = nRT

  • P is pressure
  • V is volume (in Liters)
  • n is amount of moles
  • R is gas constant - 0.0821 \frac{L \cdot atm}{mol \cdot K}
  • T is temperature (in Kelvins)

Explanation:

<u>Step 1: Define</u>

10.0 L

3.00 mol H₂

4.50 atm

<u>Step 2: Find Temperature</u>

  1. Substitute [CGL]:                    (4.50 \ atm)(10.0 \ L) = (3.00 \ mol)(0.0821 \frac{L \cdot atm}{mol \cdot K})(x \ K)
  2. Isolate temperature <em>x</em>:                                                                                    \frac{(4.50 \ atm)(10.0 \ L)}{(3.00 \ mol)(0.0821 \frac{L \cdot atm}{mol \cdot K})} = x \ K
  3. Rewrite:                                                                                                           x \ K = \frac{(4.50 \ atm)(10.0 \ L)}{(3.00 \ mol)(0.0821 \frac{L \cdot atm}{mol \cdot K})}
  4. Evaluate:                                                                                                         x = 182.704 \ K

<u>Step 3: Check</u>

<em>Round to the nearest whole number.</em>

182.704 K ≈ 183 K

The movement of the liquid in a thermometer shows changes in temperature. An increase in temperature indicates the molecules in
olya-2409 [2.1K]

Answer:

2: Moved faster and spread farther apart.

Explanation:

Restate the question: The movement of the liquid in a thermometer shows changes in temperature. An increase in temperature indicates the molecules in the liquid.

1. moved slower and closer together.

2.moved faster and spread farther apart.

3. contracted in size when heated.

4. expanded in size when heated.

Water that is cold does not have the energy to bounce of the walls, instead it is like a group of animals they group together for the warmth of the others when it gets really cold.

So it cant be 1.

We all know that power lines sag lower on a hot day (or a tire for a car, it has increases pressure). but those are different types of molecules.

So that rules out 3 and 4.

Which leaves you with 2.

The increase in temperature causes the water molecule to gain energy and move quickly, which resulted in water molecule that are farther apart and an increase in water volume.

Hope it helps!

Reconstruction failed by most other measures: Radical Republican legislation ultimately failed to isotonic former slaves from white persecution and failed to engender fundamental changes to the social fabric of the South. When President Rutherford B. federalism debate that had been an issue since the 1790s almost mediately . Hayes removed federal troops from isotonic South in 1877, former Confederate officials and slave returned to With the support of a conservative Supreme Court, these newly empowered white southern politicians passed black codes, voter qualifications, and other anti-progressive legislation to reverse the rights that blacks had gained during Radical Reconstruction. The U.S. Supreme Court bolstered this federalism anti-progressive movement federalism  with decisions in the Slaughterhouse Cases, the Civil Rights Cases, and United States v.

Try to make only one molecule of water in the simulation. Is it possible?
mel-nik [20]

Answer:

A single molecule of water has been isolated for the first time by trapping it in a fullerene cage. Water molecules are never found alone — they are always hydrogen-bonded to other molecules of water or polar compounds.

While making small volumes of pure water in a lab is possible, it's not practical to “make” large volumes of water by mixing hydrogen and oxygen together. The reaction is expensive, releases lots of energy, and can cause really massive explosions.

A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets. The atoms consist of matter that has a nucleus in the centre. The difference between atoms is expressed by atomic numbers.
