The equation of the last question which is 3CO2 + 4H2O has a total of 21 atoms with the following number of atoms of each element:
C= 3
C= 3H = 8
C= 3H = 8O = 10.
<h3>What is a chemical formula?</h3>
A chemical formula is defined as the expression that is used to show the chemical symbol of and element in a chemical compound and the number of atoms of those elements.
There are three main type of formula that include the following:
- Empirical formula : This is the type of chemical formula that shows the simplest whole-number ratio of atoms in a compound.
- Molecular formula: This is the type of chemical formula that shows the number of each type of atom in a molecule.
- Structural formula: This is the type of chemical formula that shows how this atoms of each element are bonded together.
The given chemical formula above is a molecular formula that contains the following number of atoms per elements:
C= 3
C= 3H = 8
C= 3H = 8O = 10. Which is a total of 21 ( green)

Explanation:
A. red, is the correct answer. A red filter only lets red light through, whether white or red light passes through it.
Hope this helps, and have a great day!
Answer:Stirring.
Explanation:Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.
