Dilute means to make it less strong.
i.e. You can dilute syrup to with water to thin it and make it less strong or sweet.
Concentrated means the mixture is reduced in order to make it stronger.
i.e. Sugar mixed with water and then boiled down will create a syrup and is a concentrated mixture.
Fruit drink, either concentrated or otherwise, is a mixture of several substances.
Concentrated mixture of HCl and HNO3
Add concentrated sulphuric acid to the mixture
Concentrated solution because it is a strong solution. It has a large amount of solute which fits the definition of concentrated solution.
Gold when put in aqua regia dissolves. Aqua regia is obtained by mixing concentrated nitric acid and concentrated hydrochloric acid.Once the gold is dissolved the metals are participated out by adding salts ( not table salt) to the mixture.

Plutonium is easily dissolved by concentrated HCl, HClO4 or HI.
Concentrated means cooked down to a pulp.

I think it makes the equation to be more balanced
A semi mixture would mean part or half of a mixture.
This mixture is called Aqua regia (Latin: royal water) or aqua regis, which is a highly corrosive, fuming yellow or red solution, also called nitro-hydrochloric acid.The mixture is formed by freshly mixing concentrated nitric acid (12M) and concentrated hydrochloric acid (18M), usually in a molar ratio of 1:3 (volume ratio 1:2) respectively.Only this mixture is capable of dissolving gold (Au).Chemical reaction equation (Be aware of toxic fumes !):Au(s) + NO3-(aq) + 4 H+(aq) → Au3+(aq) + NO(g) + 2 H2O(l)
Hydrochloric acid is a mixture, generally HCl + water.Note that in English HCl (pure, as a gas) is called hydrogen chloride.
Powdered milk is a mixture.Milk is not a compound,as it is not joined together chemically by elements.Powdered milk is just a dried version of milk,so it is a mixture,not a compound.
