Answer: Molarity of a solution : 0.416 M
In our question LiI(Lithium Iodide) is solute and we need to find the moles of LiI.
Given grams of LiI = 27.8g , Volume of solution = 500 mL
Molar mass of LiI = 133.85 g/mol
Moles of LiI = 0.208 mol
To find molarity we need volume of solution in 'L' , so we need to convert 500 mL to L.
1 L = 1000 mL
Volume = 0.5 L
Molarity = 
or 0.416 M
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of
fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
Hope this helped.
Answer: there is no real difference between the two.
Explanation:
some teachers just like to explain how a chemical reaction is anything involved with chemicals and any other process is just explained as a physical process
Answer: B
Explanation: A fluorine atom has nine protons and nine electrons, so it is electrically neutral. (neutral =0)
They generally have 4 - 7 electrons in their outer shell.
