By definition, isotopes belong to the same element with a specific atomic number. The two atoms would have the same number of protons, but differ in the number of neutrons. It can also be stated that the two atoms would have the same atomic number but different mass numbers. These are the requirements for two atoms to be called isotopes.
Answer:
2 molecules
Explanation:
From the stoichiometric equation, only 2-molecules of water is produced
Carbon 12 and carbon 14 are two isotopes of the elements carbon.the difference between carbon 12 and carbon 14 is the number r of neutrons in each atom.the number given after the atom name (carbon) indicates the numbers of protons plus neutron is an atom or iron. Atom of both isotopes of carbon contain 6 protons
1. Density is calculated by dividing the object's mass by the volume it occupies.
2. The volume may be determined by water displacement method.
3. D = m/v
Substituting the known values,
D = 10.0 g / 15.625 cm³ = 0.64 g/cm³
Answer:
Evaporation
Explanation:
Boiling the water will make it evaporate, leaving the solid at the bottom of the solution
