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.

Calculate the moles and grams of solute in each solution. D. 2.0 L of 0.30M Na2SO4. I already have A, B, and C. Thanks!
e-lub [12.9K]
Find the number of moles
C = n / V
C(Concentration) = 0.30 moles / L
V ( Volume) = 2 L
n = ??
n = C * V
n = 0.30 mol / L * 2 L
n = 0.60 mol


Find the molar mass
2Na = 23 * 2 = 46 grams
1S   = 32 * 1 = 32 grams
O4   = 16 * 4 = 64 grams
Total =            142 grams / mol

Find the mass
n = given mass / molar mass
n = 0.06 mol
molar Mass = 142 grams / mol
given mass = ???

given mass = molar mass * mols
given mass = 142 * 0.6
given mass = 85.2 grams. 

85.2 are in a 2 L solution that has a concentration of 0.6 mol/L

What would happen to the volume of a sample of gas if the temperature was decreased at the same time the pressure was increased?
olasank [31]

Answer:

It would decrease

Explanation:

As temperature decreases the particles in the gas have less kinetic energy and therefore have less energy to overcome the bonds that hold them together and slowly move closer. Furthermore, increased pressure forces them to move closer to each other, decreasing the volume

Elements classified as metals, nonmetals, and metalloids. Can you use the periodic table to locate these groups of elements? Wha
Lemur [1.5K]

Based on the electronic configuration the elements are classified as metals, non metals and metalloids.

<u>Explanation:</u>

Periodic table consists of three major parts.

The left side consists of metals and the right side consists of non-metals and here Hydrogen element is the exception and in between those two regions we have metalloids, which has the dual character of both metals and non metals.

These elements can be grouped by means of its chemical properties and also  due to its outermost electronic configuration.

If the valence shell electrons are same they are categorized under same group.
