Answer:The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products. ... There are two oxygen atoms in the reactants and two atoms of oxygen in the product.

An ion-dipole force is a type of intermolecular force in which forces of attraction or repulsion occur between neighboring ions, molecules or atoms.
Most covalent compounds have relatively low melting points and boiling points. Covalent compounds usually have lower enthalpies of fusion and vaporization than ionic compounds. Covalent compounds tend to be more flammable than ionic compounds. When dissolved in water, they don't conduct electricity.

Answer:
1.22 g/cm³
Explanation:
Density = mass ÷ volume
Mass = 10.04 grams
Volume = 8.21 cubic centimeters
Density = mass ÷ volume
= 10.04 ÷ 8.21
= 1.2228989037758 g/cm³
Approximately
1.22 g/cm³ to 2 significant figure.
The final answer should be approximated to 2 significant figure because the mass and volume of the objective given is in 2 significant figure
