A chemical combination of two or more elements is a compound.
Two.(Two carbons, one oxygen so just two elements.)
A chemical reaction in which two elements or radicals change places with two other elements is called double replacement. It is also known as double displacement. Its general pattern can be written as AB + CD --> AD + CB
SO4 contains the elements sulphur and oxygen in the respective ratios of 1:4.
There are two elements in NiL2, Nickel and Lithium.
There are two elements, namely sodium and oxygen.
a synthesis reaction or a combination reaction
it is the combinatin of the rational comprehensive and the incremental decision making models.
it is the combinatin of the rational comprehensive and the incremental decision making models.
A compound is composed of two or more elements. A compound of only two elements is a binary compound.
Two.(Two carbons, one oxygen so just two elements.)
If two elements are joined together it is a compound
Iron is NOT made up of two elements. Iron is an element in its own right. It is found in the Periodic Table of Elements as 'Fe'. 'Fe' is the initials of the Latin name for iron, which is Ferrum. However, iron is mined as iron ore, which is an oxide of iron. It is a chemical combination of iron and oxygen. These are possibly the two elements you are thinking about. As oxides of iron can be found in different forms ( oxidation states). They Are. :- Fe3O4 ; Magnetite. (Lodestone of early navigation). Fe2O3 ; Iron (III) Oxide [ Ferric oxide) the common iron ore. FeO ; Iron (II) Oxide (Ferrous oxide) FeS ; Iron (II) Sulphide (Much less common. Iron metal is NOT found uncombined.
Helium and Neon are considered the two most inert elements.
The set of elements that are elements of the two (or more) given sets is called the intersection of the sets.
No, elements are pure substances. However, if you mix two elements together, it depends on how well you mix them. Mixtures of two elements can be completely homogeneous, or extremely heterogeneous.
iron and gold
two numbers with a product of 1 are called elements
