Molecules of carbon dioxide are linear. What type of force exists between<br>these molecules?​
Vadim26 [7]

London Dispersion forces

Explanation:

London dispersion forces exists between the molecules of CO₂. These are weak attractions found between non-polar (and polar) molecules(symmetrical molecules).

  • This attraction sometimes makes non-polar molecules polar.
  • This is because of the uneven charge distribution caused by the constant motion of its electrons.
  • A temporary dipole or instantaneous dipole induces the neighboring molecules to become distorted and forms dipoles as well.
  • The forces are the weakest of all electrical forces.

Identify 3 physical changes that could occur with a sheet of paper
VladimirAG [237]

Answer:

  • 1. Dimensions: The sheet can be cut into several smaller pieces.

  • 2. Shape: the sheet can be formed into a paper ball or any other shape (using origami for example).

  • 3. Color: You can use crayons to paint the sheet and change its color.

Explanation:

<em>Physical changes</em> do not change the chemical properties. They do not transform the compounds that form the substances. They do not break and or form chemical bonds.

When you change the form, the state (solid, liquid or gas), the color, you are just changing physical properties.

Only chemical changes change the compounds that form the substance. For instance, if you burn the <em>sheet of paper</em>, then you are causing a chemical change because the organic matter in the paper will react with oxygen forming CO₂ and water, but by cutting, folding, smashing, or coloring with crayons, the compounds in the<em> sheet of paper</em> do not change.
