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.

What is the total number of liters of SO3 produced when 32.0 of SO2 reacts completely
ahrayia [7]
Write  the   chemical  equation   for  reaction
that  is  
2SO2+O2  --->2SO2

find  the   moles  of  SO2   used  =  moles=mass/molar mass  of  so2

=  32g/80g/mol=0.4 moles

by  use  of  reacting  ratio  between  SO2   and  SO3   which   is   2:2  therefore  the  moles  of  so3  is  also =  0.4  moles

STP  1 mole  =  22.4L.
what  about  0.4moles

= 0.4 /1 x22.4=8.96 liters

Chemistry honors list of chemical compounds and its physical properties
Feliz [49]

solution:

Physical properties describe how a material looks. such as color, state of matter, shininess, Other physical properties include density, mp, bp, brittleness, malleability, conductivity, ductility, solubility in water. A physical property can be determined without changing the identity of the material.  

Chemical properties describe how a material behaves.such as does it burn, does it corrode, does it react with air, does it react with water, does it act like a metal by giving away electrons o like a nonmetal by taking electrons, what type of bonds will it form, or is it inert, is it acidic or basic, Chemical properties can only be determined during a chemical reaction.
