Determining the number of atoms in a jar of liquid task most likely involves a calculation that uses moles.
The term mole is defined as a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
A mole is the amount of material including 6.023 × 10²³ particles. 1 mol = 6.023 × 10²³particles. This number is also called Avogadro's number.
In determining the number of atoms that makes up a substance, the number of moles is very necessary.
The mole is the favorable unit of quantity of particles. It can be likened to a quantity of things in everyday life like a dozen, a score and a gross.
A mole of any substance contains 6.023 x 10²³ particles
These particles can be atoms, protons, neutrons, electrons etc.
Thus, to find the number of atoms, we must know the number of moles.

Your answer is: determining the number of atoms in a jar of liquid.
evaporation
condensation
transpiration
Answer : The correct option is, evaporation
Explanation :
Evaporation : It is a type of process in which the phase changes from liquid state to gaseous state at constant temperature.
Condensation : It is a type of process in which the phase changes from gaseous state to liquid state at constant temperature.
Precipitation : It is a type of process in which the solid is formed when the reaction occurs in liquid solution.
Transpiration : It is a process in which the water moves from roots of the plant to the small pores. That means the movement of water through the plant.
When water changing from a liquid to a gas is an evaporation.
Hence, the correct option is, evaporation.
Answer:
The answer is evaporation
Answer: I think its c (germanium)
Explanation:
I know what you're asking but I don't think the question is stated properly. Technically, an atom will not join with an "oxide" ion; i.e., the oxide ion is an atom of oxygen to which two electrons have been added. An oxide ion will add to 2 K ions or 1 Ca ion. The K ion has lost just one electron so it takes two of them to equal the 2- charge on the oxide ion whereas the Ca ion has lost two electrons and it takes only one of them to equal the charge on the oxide ion.
The given Lewis structure does not show valid resonance form. So,the given statement is false.
The Lewis structure is the representation of the of valence shell in the molecule.
The electron present in outermost shell and which involve in chemical bond formation is called valence electron.
Resonance is way to explain the localisation of electron in molecule where Lewis formula fails to describe.
The given statement is false because both structure shows different number of valence electron.
