The phases of matter are its physical properties. Salt is made of of elements that have combined chemically. They are sodium and chlorine, that combine to create the compound which is known as table sale.
Helium and magnesium are both elements because they consist of only one type of atom. In contrast, compounds are made up of two or more different elements chemically bonded together. Helium and magnesium exist in their pure forms as single atoms without being chemically combined with other elements.
Water is a compound because its molecules are formed of chemically combined elements (hydrogen and oxygen) in a fixed proportion. A mixture is a combination of separate atoms, molecules, or particles that are not chemically bonded or in any fixed proportion.
Oxygen is chemically active because it reacts with other chemicals such as hydrogen to form water.
Water in a swimming pool is compound because the water and chlorine have been chemically combined.
Neon is chemically inert and doesnt combine with lithium
compound. Because a compound is chemically combined of 2 elements
Water is pure substance because it is two elements chemically combined, rather than just mixed.
Water is pure substance because it is two elements chemically combined, rather than just mixed.
no because they arent chemically combined
A compound is defined as a pure substance made up of two or more types of elements (atoms) chemically combined in a fixed proportion, and it can be further subdivided into simpler substances by chemical means only.A molecule is the smallest part of a compound, whose properties are the same as those of the compound.
It is a compound because it has two or more elements (in this case 3) chemically bonded together in a fixed ratio and structure. It is composed of the elements magnesium, sulfur, and oxygen.
Helium and magnesium are both elements because they consist of only one type of atom. In contrast, compounds are made up of two or more different elements chemically bonded together. Helium and magnesium exist in their pure forms as single atoms without being chemically combined with other elements.
a pure substance is something that hasn't been chemically combined with another substance and this relates to elements and compounds because on the periodic table the compounds are chemically mixed. hope this helps you by the way you didn't wwrite elements the correct way, you spelt it elaments!
Water is a compound because its molecules are formed of chemically combined elements (hydrogen and oxygen) in a fixed proportion. A mixture is a combination of separate atoms, molecules, or particles that are not chemically bonded or in any fixed proportion.
Oxygen is chemically active because it reacts with other chemicals such as hydrogen to form water.
Because you can not see the chemicals that are chemically combined.
Hydrogen bromide (HBr) is a compound because it consists of two elements (hydrogen and bromine) that has been chemically combined to form a new substance. It is a colourless gas with an acrid odor at room temperature.
