What is the ratio of elements in a compound?
The ratio of elements in a compound is determined by the number of atoms of each element present in the compound. This ratio is represented by the chemical formula of the compound, showing the types and numbers of atoms involved in the chemical bonding.
Which type of substance is composed of two or more different kinds of elements always in the same ratio?
Two or more different elements that are chemically combined in a definite ratio is a compound. Based on the nature of the bonds, it can be called an ionic compound (i.e. atoms bonded together by ionic bonds) or an molecular compound (i.e. atoms bonded together by covalent bonds).
What is the ratio of phosphorous atoms to oxygen atoms in the compound?
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
What are definite proportions?
Definite proportions, also known as the law of definite proportions, states that a chemical compound always contains its component elements in fixed ratio by mass, regardless of the amount or source of the compound. For example, water (H₂O) is always composed of 2 hydrogen atoms and 1 oxygen atom, resulting in a consistent mass ratio of approximately 1:8. This principle is fundamental in chemistry, as it supports the idea that compounds have specific formulas and compositions.
What is a material that is made up of two or more different kinds of atoms joined by chemical bond?
A material made up of two or more different kinds of atoms joined by a chemical bond is called a compound. In a compound, the atoms are chemically bonded together in a fixed ratio, creating a distinct substance with unique properties. Examples include water (H2O) and table salt (NaCl).
The ratio in which atoms are blended together in compounds is shown by an?
By the law of definite proportions.
What is the ratio of elements in a compound?
The ratio of elements in a compound is determined by the number of atoms of each element present in the compound. This ratio is represented by the chemical formula of the compound, showing the types and numbers of atoms involved in the chemical bonding.
Is ratio of atoms is always the same in a compound?
Generally yes (the law of definite proportions); as exceptions - nonstoichiometric compounds.
What has definite ratio of components?
A compound has a definite ratio of components.
How is a molecule?
A molecule is a group of atoms joined together by covalent bonds. If it is a molecule of element , atoms of the same element combine in a definite number . for example: a chlorine molecule Cl2, an oxygen molecule O2, etc. If it is a molecule of a compound , atoms of two or more atoms of different elements combine in a definite ratio. for example: H2O, water, or C6H12O6, glucose. It was formerly defined as the smallest particle of a substance that can exist independently, but in modern usage it is not applied to ionic compounds such as calcium oxide, which are giant assemblies of ions.
What is the single element or a compound that has definite properties?
An example of a compound that has definite properties is water, which always consists of two hydrogen atoms and one oxygen atom in a fixed ratio.
What are two or more different atoms are combined in definite proportion?
A simple definition is: a chemical compond has the elemental components in a fixed ratio.
When two or more different elements joined together in fixed proportions is known as?
A compound is the pure substance formed from the chemical combination of two or more different elements in a fixed ratio.
Examples of the law of definite composition?
The law of definite composition states that chemical compounds always contain the same elements in the same proportions by mass. For example, water always consists of two hydrogen atoms and one oxygen atom in a 2:1 ratio by mass. Additionally, carbon dioxide always contains one carbon atom and two oxygen atoms in a 1:2 ratio by mass.
Does metal have a definite ratio of components?
No. The reason depends on the metal. If it is a single metal element then there is only one component, and thus nothing to compare it with in a ratio. If it is an alloy then there are multiple components, but not in a definite ratio.
What is the compound ratio of P2O5 of phosphorus atoms to oxygen atoms?
This ratio is 2/5.
Which type of substance is composed of two or more different kinds of elements always in the same ratio?
Two or more different elements that are chemically combined in a definite ratio is a compound. Based on the nature of the bonds, it can be called an ionic compound (i.e. atoms bonded together by ionic bonds) or an molecular compound (i.e. atoms bonded together by covalent bonds).
