Answer:

3.01×10²³ atoms of calcium

Explanation:

number of moles = number of atoms/Avogadro's constant

n = N/NA

N = n×NA = 0.500 mol×6.02×10²³ mol^-1

N = 3.01×10²³ atoms of calcium

Explanation :

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

$A+BC\rightarrow AC+B$

In this reaction, A is more reactive element and B is less reactive element.

As per question, when gold (IV) iodide react with bromine to give gold (IV) bromide and iodine.

The balanced chemical reaction will be:

$AuI_4+2Br2\rightarrow AuBr_4+2I_2$
