Is the description three substances present two phases present is correct for compounds?
The description "three substances present, two phases present" is not typically correct for compounds. A compound consists of two or more elements chemically bonded together in a fixed ratio and is considered a single substance. In contrast, the phrase suggests a mixture of different substances that may not be chemically bonded, which would imply the presence of multiple phases. Therefore, the correct description for a compound would focus on its uniform composition and single phase.
Does lithium chloride in water form new substances?
When lithium chloride dissolves in water, it forms lithium ions (Li+) and chloride ions (Cl-), which are already present in the compound. No new substances are formed, only the compound dissociates into its constituent ions in the solution.
Is distilled water a element compound or mixture?
Distilled (pure) water is a compound; it is composed solely of H2O molecules, with no other substances present.
Does a compound not always retain the properties of the substanes that make it up?
A compound does not always retain the properties of the substances that make it up. The properties of a compound are determined by the arrangement of atoms and the type of chemical bonds present, which can result in new properties not seen in the individual elements.
How many uranium atoms are present in this compound?
Which compound
Are compounds of the element?
The elements of a compound are the chemical bonds that are present in a specific ratio in a compound. Elements are pure chemical substances that are made of the same atom.

What does the chemical formula tell about a compound and why is that important?
The chemical formula of a compound provides information about the types and numbers of atoms present in the compound. It is important because it allows scientists to understand the composition of the compound, predict its properties, and determine how it will interact with other substances.
How is the formula in a compound useful?
The formula of a compound shows the ratio of elements present in the compound. This is helpful in understanding the chemical structure and properties of the compound. It also allows for predicting how different elements will combine to form new substances.

Is distilled water a element compound or mixture?
Distilled (pure) water is a compound; it is composed solely of H2O molecules, with no other substances present.
The composition of a mixture can vary unlike a compound?
Yes, in a mixture, the substances are physically combined and can be present in any proportion. This allows the composition to vary, unlike a compound where the elements are chemically combined in fixed ratios.
Does a compound not always retain the properties of the substanes that make it up?
A compound does not always retain the properties of the substances that make it up. The properties of a compound are determined by the arrangement of atoms and the type of chemical bonds present, which can result in new properties not seen in the individual elements.
What are some substances that can be separated into simpler substances only by chemical means?
Compound substances.
