No, the chemical compound S8 is not a heterogeneous mixture. It is a pure element consisting of sulfur atoms bonded together in a molecule.
There are 21 atoms, because there are 9 atoms of Carbon 8 atoms of Hydrogen and 4 atoms of Oxygen.
Sulfur
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.
In O2, the atoms involved are two oxygen atoms. Oxygen is an element with atomic number 8, meaning each oxygen atom contains 8 protons in its nucleus.
No, the formula S8 represents an element (sulfur) rather than a compound. It indicates that there are 8 sulfur atoms bonded together.
The element C8H12 is composed of 8 carbon atoms and 12 hydrogen atoms, totaling 20 atoms in total.
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).
No, the chemical compound S8 is not a heterogeneous mixture. It is a pure element consisting of sulfur atoms bonded together in a molecule.
There are 8 atoms in the compound K3PO4, consisting of 3 potassium (K) atoms, 1 phosphorus (P) atom, and 4 oxygen (O) atoms.
The molecular formula 2C6H8O7 represents two molecules of C6H8O7. To calculate the total atoms, we multiply the number of atoms in each element by the subscript of that element in the formula. In this case, there are 2(6 carbon atoms) + 2(8 hydrogen atoms) + 2(7 oxygen atoms) = 24 carbon atoms + 16 hydrogen atoms + 14 oxygen atoms = 54 total atoms in 2C6H8O7.
There are 4 calcium atoms, 8 chlorine atoms, and 2 carbon atoms in 4CaCl2 (calcium chloride).
Oxygen is composed of oxygen atoms, each containing 8 protons, 8 neutrons, and 8 electrons. It is a diatomic molecule, with each molecule consisting of two oxygen atoms bonded together.
Hydrogen - 8 Oxygen - 4 Carbon - 9 So, shorthand formula is C9H8O4 = aspirin
There are 21 atoms, because there are 9 atoms of Carbon 8 atoms of Hydrogen and 4 atoms of Oxygen.
Sulfur
Oxygen is both a compound and an element. In nature, Oxygen forms bonds with itself to form a compound consisting of two elemental oxygen atoms to form one compounded oxygen molecule. This is O2.
