Identify 3 physical changes that could occur with a sheet of paper

Chemistry
1 answer:
VladimirAG [237]3 years ago
6 0

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.

If you were asked to convert 1.3 mol Al to atoms, which of the following should you use for the conversion?
Irina18 [472]
"<span>6.022 * 10^23 atoms Al/1 mol Al" is the one that should be used for the conversion. Multiplying the number of moles by Avogadro's number would yield the correct result. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer helps you.</span>

Which of the following is a nonpolar molecule?
mylen [45]

<u>Answer:</u> The correct option is A) a nitrogen molecule.

<u>Explanation:</u>

Polar covalent molecules are defined as chemical compounds in which the difference in electronegativity between the atoms is not equal to 0. These molecules are formed by heteronuclear molecules.

Heteronuclear molecules are defined as the molecules which are formed by the combination of more than one type of atom having a different nucleus.

Non-polar covalent molecules are defined as chemical compounds in which the difference in electronegativity between the atoms is equal to 0. These molecules are formed by homonuclear molecules.

Homonuclear molecules are defined as the molecules which are formed by the combination of one type of atom having the same nucleus.

From the given options:

  • A) A nitrogen molecule

It is a homonuclear molecule formed by the combination of 2 nitrogen atoms

  • B) A nitrogen monoxide molecule

It is a heteronuclear molecule formed by the combination of 1 nitrogen and 1 oxygen atoms

  • C) A linear nitrogen oxide molecule (N_2O) with nitrogen in the center

It is a heteronuclear molecule formed by the combination of 2 nitrogen and 1 oxygen atom and has some dipole moment. Thus, is considered a polar molecule

  • D) A bent nitrogen dioxide molecule (NO_2) with nitrogen in the center

It is a heteronuclear molecule formed by the combination of 1 nitrogen and 2 oxygen atoms and has some dipole moment. Thus, is considered a polar molecule

Hence, the correct option is A) a nitrogen molecule.
