a mixture means there are no true bonds between the atoms. Molecules have either ionic or covalent bonds between the atoms.
Cranberries are a fruit and therefore are composed of hundreds of different chemicals, not one.
A pure substance is by definition composed of one compound. A compound may be composed of different elements.
Yes. Everything is composed of molecules (except for molecules themselves).
Substances made up of two or more different molecules are called compounds. An Ionic compound is made up of a non metal and a metal while a covalent compound is made up of a non metal and another non metal. There is no such thing as a compound composed of a metal and a metal.
Cellulose makes up the cell walls of plant cells. Cellulose is composed of glucose molecules.
Molecules have properties that are different from those of the elements of which the molecules are composed.
If you mean a substance made up of only one atom, that would be a mono-atomic element, and would be a noble gas.If you mean a substance made of only one kind of atoms, that would be an element.
Skin is a heterogeneous mixture, composed of many different cells, which are composed of many different compounds. Polarity is decided by the configuration of the molecule. Because it is made of many different molecules, it is neither.
a compound
Temperature itself is not a substance and is not composed of atoms or molecules. However it is a measure of the activity of the atoms or molecules of the substance you are measuring the temperature of. That is, the warmer a substance becomes the more active are its atoms and the higher its temperature.
No, an eyeball is not a molecule. But the organic substance that makes up our bodies, including eyes, is composed of molecules.
clearly,chemical means a substance composed of atoms.
No. Pumpkin is made up of many different molecules composed of different elements.
Cranberries are a fruit and therefore are composed of hundreds of different chemicals, not one.
Are compounds composed OF molecules? Yes they are.
A pure substance is by definition composed of one compound. A compound may be composed of different elements.
A substance composed of two or more atoms of the same element is just a pure substance/element, a substance composed of different atoms is called a compound
