Nonexamples of mass include concepts or entities that do not possess mass. Examples of such nonexamples are thoughts, emotions, energy, and light.
Nonexamples of mass include concepts or entities that are not considered to have physical substance or do not exhibit the property of mass. Some nonexamples of mass include ideas, emotions, time, and mathematical concepts. These entities are abstract and do not possess the physicality or measurable mass associated with material objects.
While thoughts and emotions are subjective experiences within the mind, energy and light are forms of radiation or wave-like phenomena that do not have a measurable mass component. Mass is a property associated with matter, which refers to the physical substance that occupies space and possesses inertia.

Answer:
The radioactive dating method is one of the efficiently used methods in order to calculate the age of the rocks, meteorites, fossils and various other objects, depending upon the rate at which radioactive isotopes decay. In this method, an unstable element changes into a stable one, releasing some amount of radiation and losing a certain amount of energy.
This is efficient in determining the age of the earth. The earth is comprised of rocks that are present from the time of its formation. These rocks can be dated using this method and the approximate age of the rock is evaluated.
The Uranium-Lead dating (²³⁸U-²⁰⁶Pb) method was used to date the smaller zircon crystals of Australia that are about 4.4 billion years old. The half-life of U-238 is approximately 4.5 billion years, which shows that these are one of the oldest rocks on earth and helps in understanding how old the earth is.
Half-life is defined as the time required by a radioactive isotope to decay half of its atoms.
So the radioactive dating method is one of the common method gives the approximate age of the earth.
Answer:
So, we rely on radiometric dating to calculate their ages. Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
Explanation:
radiometric dating is a very accurate way to date the Earth.We know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes. When an unstable Uranium (U) isotope decays, it turns into an isotope of the element Lead (Pb).
There are 337.23 × 10²³ atoms in 4 moles of aluminum sulfite Al₂(SO₃)₃.
Explanation:
The questions ask how many atoms are in 4 moles of aluminum sulfite Al₂(SO₃)₃?
To answer this we use the Avogadro's number to devise the following reasoning:
if in 1 mole of Al₂(SO₃)₃ there are 14 × 6.022 × 10²³ atoms
then in 4 moles of Al₂(SO₃)₃ there are X atoms
X = (4 × 14 × 6.022 × 10²³) / 1 = 337.23 × 10²³ atoms

Answer:
The larger the species, the further away from the nucleus the outer electrons are and hence the less strongly they are held. This means the bigger atoms will be more polarizable. So, the order from biggest-smallest molecules (strongest to weakest IMF) is iodine, bromine and finally chlorine.

Answer:
The balanced chemical equation is :
Explanation:
The chemical equation in which number of atoms in reactants is equal to products is called balanced equation.
Formula of , Beryllium Chloride :
Beryllium Nitrate :
Silver Chloride :
Silver Nitrate :
When beryllium chloride reacts with dissolved silver nitrate in water , following reaction occur :
The number of atoms in reactant as well as in products are balanced :
Be = 1
Ag = 2
N =2
O = 6
Cl = 2
This is a chemical reaction involving beryllium chloride and silver nitrate in water, resulting in the formation of solid silver chloride and aqueous beryllium nitrate.
The question pertains to a chemical reaction in aqueous solution between beryllium chloride and silver nitrate. This reaction can be described by the equation BeCl2(aq) + 2AgNO3(aq) → 2AgCl(s) + Be(NO3)2(aq). In this equation, (aq) represents compounds dissolved in water (aqueous), and (s) represents solid. This reaction results in a precipitate of silver chloride (AgCl(s)), which is a powder, and an aqueous solution of beryllium nitrate (Be(NO3)2a).
