What two elements are chemically combined in a compound?
atoms of hydrogen and oxygen chemically combined to form water
What compounds does mercury make?
Mercury is able to be combined with many chemical elements.
Which chemical elements are combined to make molecules of starch and cellulose?
Carbon, hydrogen, oxygen.
What are the scientific symbols for compounds called?
Compounds are one or more elements combined to make a compound. Like H2o is oxygen and hydrogen combined.
Why are elements considered to be the alphabet of matter?
It the same way that 26 letters of the Roman alphabet can be combined together to make all the words in the English language - and similarly for most other languages - elements can be combined to make compounds. Elements and compounds can form mixtures and these three types account for most normal matter.
What are the 2 common elements that are combined to make the formula of water?
Hydrogen and Oxygen
Elements are combined to make compounds?
Yes, chemical compounds are made up of elements combined together.
What are two common elements that are combined to make a formula for water?
Hydroden and oxygen. H2o
What elements are combined to make up water?
two elements hydrogen and oxygen is used to make water i.e H2O . there are two molecules of hydrogen and one molecule of oxygen
What are elements used to create?
Elements are combined into molecules, which, when combined in big groups, make up the things that are around us. Ex: H = Hydrogen, 0 = Oxygen, H₂O = Water
How is water derived from two gases?
When two or more elements are combined to make a compound, water, the new compound can have completely new properties(water is a liquid at room temperature ,while hydrogen and oxygen (elements in the water) are both gases at room temperature),or they can have similar properties to their elements
What describes a compound?
Any two or more elements, that are chemically combined to make a new substance. e.g. water,(H2O) , Sodium hydroxide (NaOH), Ethanoic acid (CH3COOH)
What two elements are chemically combined in a compound?
atoms of hydrogen and oxygen chemically combined to form water
When elements are combined to form compounds do their properties change?
Almost all elements can be combined into compounds, for example water=h20 steel=iron and carbon. Their properties usually change. For example when carbon is added to iron to make steel, it becomes stronger and more durable. Humans use compounds to our advantage, adding various elements to materials to make them water proof, stronger, more flexible, harder e.g
What elements are combined to make salt?
Na:Sodium Cl:Chlorine NaCl= Salt
What elements makes up compound?
two or more different elements
What compound does arsenic make when combined with other elements?
