David says, "Pure honey has nothing else added." Susan says, "The honey is not really pure. It is a mixture of many different substances." Who is right? Explain your answer.

Susan is right

Explanation:

Honey is a natural substance extracted from bees. Like every other natural substance, honey is a mixture of many different substances. An analysis of the so called 'pure honey' will reveal that many chemical species compose the natural substance called honey.

Hence Susan is right when she says that honey is not really pure but a mixture of substances.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
