That would be a compound. Combine the elements of hydrogen and oxygen, and get a compound (water) that is quite different from the two gasses you started with.

Sap is a liquid produced by plants, it has nothing to do with the properties of elements.
A product is a substance formed during a chemical reaction. It is the result of the reaction's course and might have different physical or chemical properties than the reactants.
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
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?"

a substance produced when elements combine and whose properties are different from each of the elements. that's a compound. a mixture is a composition of two or more substances that are not chemically combined with each other and are capable of being separated. a compound is like C6H12O6 or glucose (plant sugar) or H2O and a mixture is like a pizza, with many different compounds.
Elements can be combined in several different ways. Elements which undergo no chemical reactions when combined are called mixtures. Normally, the elements in a mixture retain their original properties, but metals can be combined into mixtures called alloys to produced new properties, though these properties tend to be the intermediate sum of the collective properties of the metals involved. Elements which combine chemically to produce entirely new substances are called chemical compounds.
When elements chemically bond together a new chemical is produced
These substances are called products in English.
