MFe: 56 g/mol
..........
56g ----- 1 mol
5g ------- X
X = 5/56 = 0,089 moles of Fe
56g ----- 6,02×10²³ atoms
5g ------- X
X = (5×6,02×10²³)/56
X = 0,5375×10²³ = 5,375×10²² atoms of Fe

A heterogeneous mixture is not uniform in composition. Hence, option C is correct.
<h3>What is a heterogeneous mixture? </h3>
A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.
This substance is not an element or compound, because different components could be observed in the substance.
A pure substance is made up of only one type of atom (element) or only one type of molecule (compound), mixtures and solutions are made from two or more types of pure substances.
For example, aluminium is an element and ammonia is a compound.
This substance is not a homogeneous mixture, because different samples of the substance appeared to have different proportions of the components.
Hence, this substance is a heterogeneous mixture.

Sample Response:<span> The brain, through the nervous system, sends signals to the muscular system, causing the muscles to move rapidly. This rapid motion produces heat in the body and is observed as shivering. The brain also sends signals to the muscles right beneath the skin. These muscles shorten and tighten, causing the hairs on the skin to stand up. When the hairs stand up, heat is kept in the air trapped within the hairs, which keeps the body warm.</span>
