Compare physical and chemical change?
A chemical change results in the formation of new substances eg hydrogen explodes in the presence of oxygen when lit to form water. The water is not the same as hydrogen and oxygen and there was also a change in energy. A physical change does not change the nature of the substance eg freezing water means one still has water, cutting wood into sawdust, dissolving salt into water.
What facts about characteristic chemical and physical properties make it possible for sientist to compare and classify matter?
Scientists can compare and classify matter based on its chemical properties such as reactivity, flammability, and ability to form bonds with other substances. Physical properties such as melting point, boiling point, density, and conductivity also provide valuable information for classifying matter. By studying these properties, scientists can identify similarities and differences between different substances to categorize them accordingly.
How do the physical and chemical propertys of the halogens compare with those of the inert gases?
Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.
Where can you compare balancing chemical equation in real life?
We can compare balancing chemical equation to a mother and her children. She should be fair in giving the things that her children want. She should be equal. :)
How do the physical and chemical properties of the halogens compare with those of the noble glasses?
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
What experiment can I do that shows physical and chemical changes in fruit?
Let it rot. The physical and chemical changes are huge and can be easy shown when you compare a "good" fruit and a rotting version.
How would you compare physical and chemical properties and physical and chemical changes?
Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as color or density. Chemical properties describe how a substance interacts with other substances, like its ability to rust or burn. Physical changes alter a substance's appearance or state without changing its chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
Compare the total amount of energy before and after physical and chemical changes?
In physical changes, the total amount of energy before and after remains the same as no new substances are formed. In chemical changes, there may be a difference in the total amount of energy before and after the reaction due to the formation of new substances and the breaking or forming of chemical bonds.
How do the properties of substances formed in chemical changes compare to those of the original substances?
Substances formed in chemical changes have different physical and chemical properties compared to the original substances. This can include changes in color, odor, state of matter, melting/boiling points, and reactivity. The chemical composition of the new substances is also different from the original substances.
How do you find out if something is nitrogen?
You check the chemical content for nitrogen particles. You can compare the particles to the charastrics featured on the periodic table of the elements.
How do you illustrate chemical change versus physical change in a venn diagram?
by drawing 2 circles and compare and contrast chemical and physical change
Compare the total energy before and after physical and chemical changes?
Physical changes are usually reversible and chemical changes you can't usually reverse them. Frying an egg is chemical because you can't get the raw egg back. Freezing water would be physical... hope this helps! ----------- Chemical change is a change that imply modifications in the structures of molecules; new compounds appear. Ex.: burning of coal with releasing of carbon dioxide and water. Physical changes don't imply the structure modification of the molecules but only the state of matter, form, dimensions; the chemical compound remain unchanged. Ex.: grinding of coal to be used in a thermal power unit.

How do physical and chemical properties of the halogens compare with those of the noble gases?
Noble gases are not reactiveHalogens are very reactive.
Compare and contrast chemical and physical properties?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
Is colorless a physical change or a chemical change?
Colorless is a physical property. Determining change requires you to compare two things.
Compare and contrast mechanical digestion and chemical digestion?
Mechanical Digestion (or physical digestion) is more about the mouth. It's chewing, biting, breaking down, and sofening the food. This is why its called "Mechanical" Digestion.Mechanical digestion involves the pulverizing and crushing of food particles, usually by chewing. Chemical digestion occurs through the secretion of digestive juices.
