What is a elemental composition?
Elemental composition refers to the types and relative proportions of elements present in a substance. This composition can be expressed in terms of the atomic symbols and the number of atoms of each element in the substance. It provides valuable information about the chemical properties and behavior of the substance.
Why is it misleading to identify a solid compound just from a lone mp determination?
A single melting point determination may not be enough to accurately identify a solid compound because different compounds can have similar or identical melting points. Additional tests such as infrared spectroscopy, mass spectrometry, or elemental analysis are needed to confirm the identity of a compound.
Which could represent the empirical and the formula of a given compound?
The empirical formula is representative for the chemical composition of a compound; the structural formula is representative for the spatial structure of the compound.
What is the meaning of determination of formula unit of compound?
The determination of the formula unit of a compound involves finding the simplest whole number ratio of elements in the compound. This is done by analyzing the mass or moles of each element present and then determining the ratio that gives a balanced formula. It helps to establish the chemical identity and composition of the compound.
What is the probable identity of the unknown crystalline hydrate?
The probable identity of the unknown crystalline hydrate can be determined by conducting techniques such as X-ray crystallography, spectroscopy, and elemental analysis. These methods can provide information on the crystal structure, chemical composition, and properties of the compound, which can help in identifying the hydrate.
Isair a compound mixture or element?
Air is a mixture, because its elemental composition is not constant but instead varies with circumstances.
What is composition stoichiometry?
Composition stoichiometry is the study of the relative quantities of elements in a compound. It involves determining the ratio in which different elements combine to form a compound, often expressed using chemical formulas and balanced equations. Calculation of composition stoichiometry helps in predicting the mass and chemical properties of a compound based on its elemental composition.

Does salt change its structure and composition after a reaction?
After a chemical reaction any compound is transformed in other compound.
What controlled the properties of a compound?
The chemical composition and structure are important.

Is diamond a compound or a substance?
It's an elemental compound
Which could represent the empirical and the formula of a given compound?
The empirical formula is representative for the chemical composition of a compound; the structural formula is representative for the spatial structure of the compound.
Is salt water a mineral?
No. a mineral is a compound of fixed chemical composition and of fixed crystal structure.
Is water mineral salts?
No. a mineral is a compound of fixed chemical composition and of fixed crystal structure.
What is an material?
One that is in the solid state but does not have regularly ordered atomic structure, as do all elemental solids and pure compound solids at thermodynamic equilibrium.
What is a composition of a compound shown by?
The composition of a compound is shown by its chemical formula, which represents the types and number of atoms present in the compound. The chemical formula provides information about the elements present in the compound and their ratio, allowing for identification and understanding of the compound's structure and properties.
