C6H15, C2H5 has a molar mass of 29g/mol. 87 divided by 29 is 3. Then multiply each element subscript by 3
A. Atoms of chlorine (Cl)
Explanation:
The atoms of chlorine are held together by non-polar covalent bonds.
- Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference.
- For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
- This covalent bond type is called non-polar covalent bond.
- In this bond type, there is equal sharing of the electron pair between the atoms and there is no electrostatic charge on the molecule.

Physical Properties: Sodium bicarbonate is an odorless, white crystalline solid or fine powder. It has a slightly alkaline taste. Its density is 2.20 g mL-1 and it decomposes in temperatures above 50 ºC. The decomposition yields to sodium carbonate. It is highly soluble in water and poorly soluble in acetone and methanol. It is insoluble in ethanol.
Chemical Properties: Sodium bicarbonate is an amphoteric compounds, it means the compound has a character acids an basic at the same time. It is highly soluble in water, resulting in a slighty alkaline solution.
i hope this part helps i will continue to research on Toothpaste's properties
Hello there.

1) The trails left by an electron as it moves around the nucleus
The electron model dictates that the electrons have no fixed position so it traces their path.
2) 8
Atomic number is equivalent to proton number
3) Its mass is lowered, but it is still the same element.
The element's identity is due to the number of protons; however, neutrons play a large role in an atom's mass. Thus, the mass will decrease but the element will be the same. Such variants are called isotopes.
