Answer:
The steps that must be long to obtain separately the components (to the substances) of a mixture of water, salt and sand, are respectively: A) filtration and siphoning B) decanting and siphoning C) simple filtration and distillation D) collection and decantation.
Simple filtration and Siphoning is the method. When an insoluble solid is present in a liquid. Filtration is the ideal method of separation,The sand is filtered by the filtered paper as water is allowed to pass through the filter paper into a beaker where the funnel which hold the filter paper emptied into.
Water molecules is Siphoned, pull by force of gravity through the sand, past the filter paper to emerge as clean in the beaker below.
Answer:

Explanation:
Answer: 8.3 J
Explanation:
We have the following measurement:
Rearranging the units:
Since 1 Newton is 
:
Since 1 Joule is 
:
This is the simplest form possible
Molar mass of CeCl3 = 246.475 g/mol
This compound is also known as Cerium(III) Chloride.
Convert grams CeCl3 to moles or moles CeCl3 to grams
Molecular weight calculation:
140.116 + 35.453*3
