Physical: carbon is a non-metal and tin is a metal (both are solids at 25 Celsius)
Chemical: carbon and tin both have 4 valence electrons.
Breathing is a chemical process. When air is breathed in, it reacts chemically; when a person breathes out, they release more carbon dioxide than they breathed in, and less oxygen.
Gas bubbles are a chemical change. A common example can be soda. The bubbles in the soda are carbon, thus soda is carbonated, when you leave soda open and out in the open the carbon reacts with the oxygen in the air and forms carbon dioxide. Since there is a new chemical composition of the soda since it has lost carbon, also know as going flat, this is a chemical change. The above example is incorrect. The bubbles coming out of soda is not carbon reacting with oxygen;the bubbles are already carbon dioxide. Does pencil lead react with oxygen? The carbon dioxide in your soda is dissolved in solution. Gas bubbles in most other situations though ARE a sign of a chemical change.
CHEMICAL
yes
Matter have two essential types of properties, those are physical properties and chemical properties. Among its physical properties are smell, color, freezing point and boiling point, density, opacity and viscosity. Among chemical properties are reactivity with water, PH, electromotive force and heat of combustion.
A mixture contain two or more components not linked by chemical bonds; a mixture can be separated by a physical process.
For all materials physical properties are related to some characteristics as density, hardness, refractive index etc. and the chemical properties are related to some characteristics as chemical reactivity, flammability, oxydation etc. Physical properties are characterized by getting back the original material by changing its form, state, etc. Chemical properties are characterized by a complete change in the material itself i.e. you cannot get back the same material.
what are some characteristics of mold
it is physical because when the metal melts it is still metal. it doesn't change to a new subtance.--------------------------------------A metal is a chemical element, not a property; but in some situations chemist use the expression metallic characteristics (or properties).
Physical and chemical?! Right on!
no
The cellular composition of a living thing contains, carbon, nitrogen and oxygen and all living things (organisms) need water to enable chemical reactions. Inorganic things cannot carry out vital living functions such as respiration and excretion.
Diamonds are an allotropic form of carbon; they are materials having some properties, not property. Which is the scientific word for it. By Hayley
