All of the following are examples of suspensions except: muddy water italian salad dressing salt water dust particles in the air

Suspension is when particle size of solute in a solvent is more than that 100 nm

Particle size from 1nm-200nm is known as colloid

Particle size below 1nm is known as true solution

So in the given examples if we dissolve salt in water (upto its solubility) the solution obtained is known as true solution. It will not be a suspension.

In case of suspension the solute particle can be separated from solvent by simple filtration or by decanting.

When a salt like Nacl is dissolved in water we cannot separated it by simple filtration or decanting hence it is not a suspension.

the child will have heterozygous dominant chromosomes as characters of his father are dominant over the characters of his mother.

the child is heterozygous

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
