The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.
<h3>What is an atom?</h3>
An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.
The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.
The atomic mass can be given as:
The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:
The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.

Fe is undergoing oxidation while S is undergoing reduction
<h3>What is oxidation-reduction reaction?</h3>
Oxidation-reduction reaction can simply be defined as a special type of chemical reaction in which the oxidation states of substrate change. Oxidation is the

Answer: please see anbswer below
Explanation:
She made such prediction because When food colouring is added into hot water, the difussion ie spreading rate will be fast . This is due to the high kinetic energy of of the molecules which are randomly bouncing against each other causing the solution to mix faster.
When compared with water at room temperature and cold water, the particles are not moving as fast and the food coloring does not spread or diffuse as fast as the hot water because of the lower kinetic energy of molecules in the warm and cold water although the food coloring in warm water will spread faster than in the cold water.
The solubility constant or Ksp is calculated by the product of the concentration of the ions raise to the stoichiometric coefficient. We calculate as follows:
BaCrO4 = Ba2+ + CrO42-
Ksp = [Ba2+][CrO4]
Ksp = [1.08×10−5<span> ] [1.08×10−5] = 1.1664x10^-10</span>
