Answer: mass and volume
Explanation:
Divide the mass by the volume in order to get an object's Density.
The particles will move faster and further apart. There will be more energy in the particles due to the heat.
Answer:
a solution color becoming less intense due to dilution- is not an evidence of a chemical reaction
bubbles (gas formation) - evidence of a chemical reaction
explosion or fire - evidence of a chemical reaction
changes in color- evidence of a chemical reaction
precipitation- evidence of a chemical reaction
changes in temperature - evidence of a chemical reaction
a solid liquifying - is not an evidence of a chemical reaction
solution colors mixing - is not an evidence of a chemical reaction
Explanation:
A chemical change is not easily reversible and yields new substances. It is often accompanied by a loss or gain of heat.
In the answer section, i have shown some evidences that lead us to conclude that a chemical reaction has taken place. The occurrence of a chemical change often goes with the formation of new substances as earlier stated and any of these signs may accompany the process.
For instance, when a metal is dropped in dilute acid solution, bubble of hydrogen gas indicates that a chemical reaction has taken place.
Organic compounds;
- Carbohydrates lipids and nucleic acids
- contained in living organisms
- Molecules that contain carbon and hydrogen bonds
Inorganic molecules;
- Sometimes contain carbon but do not contain C-H bonds
- Molecules made of a combination of elements
- Water and table salts
<h3>What is an organic molecule?</h3>
An organic molecule are the molecules that contain long chains of carbon and are studied as part of organic chemistry. Inorganic compounds do not contain catenated carbon chains and are studied as part of inorganic chemistry.
Let us now classify the compounds;
