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.
Compare and contrast how do chemical and physical properties differ?
chemical properties deal with how an object or substance reacts to other substances (usually a solution, or gas, or some aqueous medium... any medium really). physical properties deal with the more noticeable stuff like strength, stiffness, toughness (and yes they all mean different things), brittleness, etc. etc.
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 a new substance compare with the properties of the original substances after a chemical change takes place?
After a chemical change, the new substance will have different properties compared to the original substances. The chemical reaction typically results in the formation of new bonds and rearrangement of atoms, leading to changes in physical and chemical properties such as color, smell, temperature, and composition. The new substance may have different reactivity, boiling point, melting point, and solubility compared to the original substances.
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.

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.
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.
How do the particles that make up matter compare during physical and chemical changes?
During physical changes, the particles that make up matter remain the same and only their arrangement or state changes. In contrast, during chemical changes, the particles undergo a rearrangement or bonding at the atomic level, resulting in the formation of new substances with different properties.
How do physical and chemical properties of the halogens compare with those of the noble gases?
Noble gases are not reactiveHalogens are very reactive.

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.
Compare physical and chemical properties?
A chemical property is the substance's response to other substances, resulting in a new substance. A physical property is something like a substance's lustre, melting point, boiling point, colour, or density, to name a few. Examples of chemical properties are: combustibility and reaction to acid.
How do the properties of the new substance compare with the properties of the original substance after a chemical change takes place?
Mass gets preserved (you have to consider the stuff that isn't the end produced chemical, too). Otherwise, chemical changes are known for having different properties. They could have similar properties, I imagine, but then, "Why would anybody want to make them?"

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.
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.
