If an endothermic process absorbs 256j how many kilocalories are absorbed
Finger [1]
There are several units for expressing energy, Most common are joules and kilocalories.

The conversion factor of joule to kilocalories is 
 1 kilo calorie  = 4184 J
∴ x kilo calorie = 256 J

x = \frac{256}{4184} = 0.0611 kilo calories

Thus, 256 J = 0.0611 kilocalories

What is the formula for manganese (ii) fluoride decahydrate? (you may use a * to represent the dot in the formula.)?
Rasek [7]
These types of molecules are called hydrates. They have a certain number of moles attached to the salt. Their characteristic is being hygroscopic. That means that when they are exposed to air, they readily solvate. 

The formula for Manganese Fluoride Decahydrate will involve the formula Mn, F and H₂O. In ionic form, Manganese is Mn⁺² while fluoride is in F⁻. When they are brought together, their superscripts are 'cross-multiplied' and becomes their respective subscripts. The compound becomes MnF₂. Then, we add the decahydrate which means 10 moles of H₂O. Hence, the formula for Manganese Fluoride Decahydrate is MnF₂*10H₂O.
