Answer:
Multiply 3 by Avogadro's number.
Explanation:
The mole can be defined as the amount of a substance that contains Avogadro’s number of particles, 6.02 x 10²³.
For elementary particles:
Number of particles=
number of moles x 6.02 x10²³
From the question,
Number of moles = 3moles
Number of particles = 3 x 6.02 x10²³
I think it would be minimize so u can have more friction
Explanation:
Spectator ions refers to elements/molecules that do not form part of the reaction. Basically, these elements/molecules are in the same state in the reactant and product side. From the given reaction, Ca and SO4 change their state from aqueous to solid and Na and Cl do not change their state. Therefore, Na and Cl are spectator ions and Ca and SO4 are not spectator ions.
Answer:
The correct option is C.
