What is the relationship between atoms elements compounds and mixtures explain?
- The atom is representative for a chemical element (more exactly for an isotope); elements are formed from atoms. - A chemical compound contain two or more chemical elements. - A mixture contain two or more compounds.
How do chemists explain this difference?
Chemists explain differences in properties or behavior by looking at the molecular structure of substances. Variation in molecular structure can lead to differences in physical, chemical, and biological properties. By understanding how atoms are arranged and interact within molecules, chemists can explain why substances exhibit different characteristics.
Define a compound and explain how compounds in living organisms are different from compounds in non biological materials?
A compound is a substance composed of two or more different elements that are chemically bonded together. Compounds in living organisms are more complex and contain specific molecular structures that are essential for biological functions, such as enzymes, proteins, and DNA. In contrast, compounds in non-biological materials are typically simpler in structure and serve different purposes, such as building materials or pharmaceuticals.
Why did Dalton say that a chemical reaction is a rearrangement of atoms?
Dalton proposed that a chemical reaction is a rearrangement of atoms because he believed that in chemical reactions, atoms are not created or destroyed, but rather rearranged to form different compounds. This idea helped to explain how different elements combine to form new substances without changing the total number of atoms present.
Is distillation a physical or chemical process Explain crude oil?
Distillation is a physical process where a mixture is separated based on differences in boiling points. Crude oil is a mixture of hydrocarbons that can be separated into different components through distillation in an oil refinery, where it is heated, vaporized, and then condensed back into liquid form to obtain products like gasoline, diesel, and kerosene.
What is the relationship between atoms elements compounds and mixtures explain?
- The atom is representative for a chemical element (more exactly for an isotope); elements are formed from atoms. - A chemical compound contain two or more chemical elements. - A mixture contain two or more compounds.
Is evidence of a chemical change?
Explain how a mixture of sand and salt can be separated.
180 g of glucose and 342 g of sucrose have same number of molecules but different number of atoms. Explain?
They are different compounds with different molecules:- the chemical formula of glucose is C6H12O6- the chemical formula of sucrose is C12H22O11

Explain what chemical compounds are?
Any chemical that contains multiple base elements is termed a chemical compound. Chemical compounds are substances that contain two or more base elements. For example; carbon (C) and oxygen (O) are base elements, but carbon dioxide (CO2) is a compound consisting of one carbon and two oxygen molecules.

How did dalton explain the formation of compounds?
Dalton proposed that elements combine in simple whole number ratios to form compounds, based on his atomic theory. He suggested that atoms of different elements combine in specific ratios to form compounds, where each compound has a unique composition. This explanation laid the foundation for understanding chemical reactions and the formation of compounds.
What is the theory used to explain how atoms join together?
The theory used to explain how atoms join together is called chemical bonding. Chemical bonding involves the sharing or transferring of electrons between atoms to form molecules or compounds. There are different types of chemical bonds, including covalent bonds, ionic bonds, and metallic bonds.
How did Dalton explain the diffrences between a mixture and a compound?
Dalton explained that a mixture is a physical combination of two or more substances that retain their individual properties, whereas a compound is a chemical combination of two or more elements in fixed proportions with unique and different properties from the elements that make it up. This difference is based on the idea that compounds are formed through chemical reactions that result in the rearrangement of atoms, while mixtures can be separated physically.
Explain how concrete is a mixture and not a pure substance?
Concrete is a mixture of different substances (compounds) not a sinle compound.
Why did Dalton say that a chemical reaction is a rearrangement of atoms?
Dalton proposed that a chemical reaction is a rearrangement of atoms because he believed that in chemical reactions, atoms are not created or destroyed, but rather rearranged to form different compounds. This idea helped to explain how different elements combine to form new substances without changing the total number of atoms present.
Explain why elements and compounds are pure substances while a homogeneous mixture is not?
The difference between a homogeneous mixture and a pure substance is that a pure substance has a fixed composition and cannot be separated because it is chemically bonded and a homogeneous mixture can be separated.
