Answer:
138.39 g/mol
Explanation:
Formula mass is a synonym for molar mass, which is the sum of all the masses of the elements. These can be found on a periodic table.
Because this is hydrated, the formula needs to include H2O.
MgSO4 + H2O
Mg + S + 4O + 2H + O
24.31 + 32.07 + (4*16) + (2*1.008) + 16 = about <u>138.39</u>
Answer:
The correct answer is The overall enthalpy of the system increases during the change.
Explanation:
Exothermic is type of chemical reaction that deals with the generation of energy in form of heat.Exothermic reactions are thermodynamically favorable because free energy change during exothermic reaction is highly negative.
Enthalpy is a state function which measures the heat content of the system.As there is a generation of heat from the reaction to the system in which the reaction is taking place,the heat content of the system increases which ultimately result in increasing the overall change of the enthalpy.
Answer:
simple distillation
1)It is used to seprate mixture of two miscible liquids having different boiling points.
fractional distillation
1)It is used to separate the mixtore of two or more liquids of close boiling range.
simple
2)In simple distillation, there is no fractional column.
fractional
2)In fractional distillation, a fractional column is used.
- It Is A Combination Reaction; Nitrogen & Hydrogen Combine to form ammonia
<h3>Hope It's Helps~</h3>
Because they break down easy when heated (thermal decomposition) to form two or more products
