Answer: please see anbswer below
Explanation:
She made such prediction because When food colouring is added into hot water, the difussion ie spreading rate will be fast . This is due to the high kinetic energy of of the molecules which are randomly bouncing against each other causing the solution to mix faster.
When compared with water at room temperature and cold water, the particles are not moving as fast and the food coloring does not spread or diffuse as fast as the hot water because of the lower kinetic energy of molecules in the warm and cold water although the food coloring in warm water will spread faster than in the cold water.

19.927 moles are in 1.20 times atoms of phosphorus.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others.
1 mole of any substance contain Avogadro's number of molecules so we can calculate the number of moles by dividing the provided number of atoms over Avogadro's number to obtain the number of moles .
Moles=
Moles= 1.20 X atoms ÷ 6.022 X
= 19.927
Hence, 19.927 moles are in 1.20 times atoms of phosphorus.

A catalyst is a substance added to the reaction that lowers the activation energy by providing an alternate pathway for the reactions to go to completion.
A catalyst is a substance that accelerates a chemical response, or lowers the temperature or strain needed to begin one, with out itself being ate up at some stage in the response. Catalysis is the procedure of adding a catalyst to facilitate a response.
Catalysts may be categorized as homogeneous, heterogeneous, or enzymatic. Homogeneous catalysts exist inside the identical phase as the reactants, whereas heterogeneous catalysts exist in a exclusive section than the reactants.
Catalysts are basically categorised into 4 kinds.Homogeneous, Heterogeneous, Heterogenized homogeneous catalyst and Biocatalysts. Homogeneous catalyst: In homogeneous catalysis, reaction mixture and catalyst both are gift inside the equal segment.
