When the elements combine to form compound how many are there?
Different compounds have different numbers of constituent elements. here is no set number.
How do you identify a compound or an element?
Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.
What is a combination of symbols and numbers that describes a molecule?
A combination of chemical symbols that show what elements make up a compound and the number of atoms of each element in the smallest unit of the compound is a chemical formula.
The statement that when two elements combine to form two or more compounds the mass of one element that combines with a given mass of the other element is in the ratio of small whole numbers is know?
That is known as the law of definite proportions
What law is described by the fact that the ratio of the mass of oxygen in carbon dioxide to the mass of oxygen in carbon monoxide is 2 to 1?
This statement illustrates the law of multiple proportions, which states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. You can also put it this way: When two elements (A and B) combine to form more than one compound, the different masses of B that combine with a fixed mass of A are in a simple ratio.

What are the subsets of a pure substance?
An element and compound. Element- A group of atoms with identical proton numbers, Compound- 2 or more DIFFERENT elements chemically held together.

Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.
What is the atomic number for Nacl?
doesn't have one, its a compound. only elements have atomic numbers, which is the number of protons the element has.
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
What law is described by the fact that the ratio of the mass of oxygen in carbon dioxide to the mass of oxygen in carbon monoxide is 2 1?
This statement illustrates the law of multiple proportions, which states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. You can also put it this way: When two elements (A and B) combine to form more than one compound, the different masses of B that combine with a fixed mass of A are in a simple ratio.
Which best describes john Dalton's observations of elements in any given compound?
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.
What is the law if multiple proportions?
If two elements (A and B) form more than one compound between them, then the ratios of the masses of the second element (B) which combine with a fixed mass of the first element (A) will be ratios of small whole numbers. Examples: CO, CO2 SO, SO2, SO3 SiO, SiO2 NO, NO2

Is CuSO4 is an example of a chemical element?
No. The multiple symbols interrupted by the numbers make it clear that this is a compound. In this case it is copper sulfate, a compound of three elements: copper (Cu), sulfur (S), and oxygen (O).
