How do you count the number of elements in a compound?

To count the number of elements in a compound, you can identify the different elements present by looking at the chemical formula. Each element is represented by a unique symbol (e.g., H for hydrogen, O for oxygen). Count the number of unique elements present in the compound to determine the total number of elements.


What determines where one row stops and another begins?

In tables, rows are typically delineated by a horizontal line or spacing that visually separates each entry. Within spreadsheets, rows are defined by numerical values along the left-hand side, indicating the row number. In databases, each row is typically represented as a record, delimited by unique identifiers or keys.


What is the chemical structure of the molecule?

I'd need to know the specific molecule you're referring to in order to provide its chemical structure. Each molecule has a unique arrangement of atoms and bonds.


Which is the limiting reactant when masses of reactants are same?

You must first convert the mass of each reactant into moles of each reactant. Having the same mass does not mean that the amount of each reactant is the same, because each reactant has its own unique molar mass. Refer to the related link below for instructions on determining limiting reactants, also called limiting reagents.


How can you figure out how many of each subatomic particle is in a atom has?

To determine the number of each subatomic particle in an atom, you need to know the atom's atomic number and mass number. The atomic number tells you the number of protons, while the mass number gives you the total number of protons and neutrons combined. Subtract the atomic number from the mass number to find the number of neutrons. Electrons will equal the number of protons in a neutral atom.

How does the atomic number identify the atoms of a particular element?

The atomic number of an element is unique to that element. The atomic number is equal to the amount of electrons in one atom of that element. As each element categorically has it's own amount of electrons, you can identify an element from this number.
