What are the materials contains components in a fixed ratio?
Compounds contain elements in a fixed ratio. This means that each compound is made up of a specific combination of elements in an exact proportion, such as water (H2O) always having two hydrogen atoms for every one oxygen atom.
What elements will always form ionic compounds in a 12 ratio with zinc.?
Elements that will always form ionic compounds with zinc in a 1:2 ratio are those from Group 16 of the periodic table, such as oxygen (O), sulfur (S), and selenium (Se). These elements typically gain two electrons to achieve a stable electron configuration, forming ions with a 2- charge that can combine with the 2+ charge of zinc.
What is a fixed proportion in chemistry?
A fixed proportion in chemistry refers to the specific ratio in which elements combine to form compounds. This means that the elements in a compound are always present in the same proportion by mass. For example, water is always composed of hydrogen and oxygen in a 2:1 ratio by mass.
Does a compound always contain at least two or more elements?
Yes, a compound is a substance composed of two or more elements that are chemically bonded together in a fixed ratio.
What is formed by the combining of elements or other compounds through chemical reactions?
A compound is formed by the combining of elements or other compounds through chemical reactions. Compounds are made up of molecules that contain two or more different elements chemically bonded together in a fixed ratio. These chemical bonds are formed by the sharing or transfer of electrons between atoms.
The scientific statement that says that compounds always have exactly the same composition by mass is?
The law of definite proportions states that compounds always contain the same elements in the same proportion by mass. This means that the ratio of elements in a compound is consistent and does not change.

What type of matter is made of elements in a specific ratio that is always the same?
Elements combined in specific ratios form compounds.

When two or more different atom combine together in a fixed ratio they produce?
a compound. Compounds are formed when two or more different elements chemically bond together in a specific ratio, creating a new substance with unique properties. The combination of atoms in compounds follows the law of definite proportions, meaning the ratio of elements in the compound is always the same.
Compounds join in a specific ratio according to their masses?
It is true for the simple compounds you are likely to meet in school chemistry. If the ratio is fixed we call it a stoichiometric compound. Sodium chloride is always NaCl and magnesium chloride is always MgCl2. Lead and oxygen can form PbO, PbO2 and Pb3O4 but each of these is a different substance and each always has a fixed elemental ratio. However there are many more complex compounds which have variable composition. A common example is rust.
What do compounds always conain exact ratios of?
Compounds always contain exact ratios of atoms of different elements. These ratios are defined by the chemical formula of the compound, which specifies the number of each type of atom present. For example, in water (H₂O), there are always two hydrogen atoms for every one oxygen atom, reflecting a fixed ratio. This consistent composition is fundamental to the identity and properties of the compound.
Does a compound always contain at least two or more elements?
Yes, a compound is a substance composed of two or more elements that are chemically bonded together in a fixed ratio.
What is formed by the combining of elements or other compounds through chemical reactions?

Compounds are made up of molecules that contain two or more different elements chemically bonded together in a fixed ratio. These chemical bonds are formed by the sharing or transfer of electrons between atoms.
What do you compounds always contain exact ratios of?
Compounds always contain exact ratios of atoms, which are represented by their chemical formulas. These ratios indicate the number of each type of atom present in the compound, ensuring that the compound has a consistent composition. For example, water (H₂O) has a fixed ratio of two hydrogen atoms to one oxygen atom. This fixed ratio is characteristic of the specific compound and distinguishes it from mixtures.
What are non -stoichiometric compounds?
Non-stoichiometric compounds are compounds that do not have a fixed ratio of elements in their chemical formula. This means that the ratio of elements in the compound can vary within certain limits. This can be due to factors such as defects in the crystal lattice or the presence of excess or deficient elements in the compound.
