Answer: Radiation
Explanation: The sun transfers heat energy through radiation since in a vacuum it does not require any medium to allow heat flow.
At a definite amount of solute and at a definite tempreture it is dissolved in utane above that it remain unsoluble
<h2>answer.</h2>
to remove iodine sublime
to remove sand filter
to remove water evaporate
Explanation:
1. put the mixture in a beaker
2.Heat the mixture using a watch glass filled with cold water, the iodine will sublime at the base of the watch glass.
3.Add water to sand and salt. Stir for salt to diffuse in the water
4.Filter sand from the solution using a filter paper
5.evaporate the remaining water to remain with Salt crystals.
To assume the empirical formula of a compound, you want the ratio of the moles of every element, and you discover that by means of the percent’s of the element as the element's mass.
As an instance, if a compound is 16% Carbon and 84% sulfur, you can round about that if you had a 100 gram sample of the compound, it would contain 16 grams of carbon & 84 grams of sulfur.
To look for the moles of carbon in that sample, you would distribute the mass by the atomic mass of carbon, so 16/12 = 1.3 moles. You do the similar calculation with the other elements. For Sulfur, you divide 84g by the atomic mass of sulfur, so 84/32 = 2.6moles of sulfur. You endure in this same way if there is more than 2 elements.
Lastly you find the ratio of the moles of every element. The unassuming way to do this is to look the element with the smallest number of moles and split the other moles by that number. In the above example 2.6 moles of Sulfur divided by 1.3 moles of Carbon equals 2. (Which is a 2:1 ratio) Therefore there is twice as numerous sulfurs as carbons in this compound, and the empirical formula is CS2.
