The mathematical statement of equality is represented by the symbol "=" and is used to show that two expressions are equivalent or have the same value. It signifies that the quantity on the left side of the symbol is exactly the same as the quantity on the right side.
There is no such thing. There are different units, depending on what exactly (what physical quantity) you want to measure.
they are exactly the same in every way except the warm ones move faster
The notation "3 CO2" indicates that there are three molecules of carbon dioxide (CO2). Therefore, in 3 CO2, there are exactly three molecules of CO2 present. Each molecule consists of one carbon atom and two oxygen atoms, but the question specifically asks about the number of molecules.
It is 67, exactly as in the question.
A mole of a substance is a unit of measurement used in chemistry that represents a specific amount of that substance. It is defined as the amount of the substance that contains the same number of particles as there are atoms in exactly 12 grams of carbon-12 (Avogadro's number, 6.022 x 10^23). A mole is used to express the quantity of atoms, molecules, or ions in a sample.
The height of this quantity of water would be exactly that much!
The importance of equilibrium price and quantity is that it creates a point where there is no pressure on the market to shift supply or demand. Suppliers supply exactly the quantity demanded.
They are exactly the same quantity.
Three molecules of hydrogen will combine exactly with one molecule of nitrogen to form two molecules of ammonia (NH3) in a balanced chemical reaction.
Because that's exactly what it is ! Apart form water molecules, sea water contains dissolved salt, heavy metals, oil, sewage, organic matter and animal faeces.
Ethanol.

The formula for methane is CH4, showing that each molecule contains exactly 5 atoms. Therefore, the number of atoms in 0.650 ml is 5 X 0.650 X Avogadro's Number, or about 1.96 X 1024 atoms, to the justified number of significant digits.
The molecules of each DNA are exactly the same, they are aranged diferently within chromosomes though.
An equilateral triangle has exactly three lines of symmetry. It is the only shape that contains exactly three lines of symmetry.
