The molecular weight for Calcium Chloride Dihydrate (CaCl2•2H20) is 2H2O.
mass of 64g/mol = 256.52 g/mol
mass of 11g/mol = 26.981538 g/mol
mass of 147g/mol= 146.9149 g/mol
258g/mol = 258.09843 g/mol
I believe it's Radon (: Hope this helps!
Answer:
NaOH
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
2NBr3 + 3NaOH —> N2 + 3NaBr + 3HOBr
The limiting reactant can be obtained as follow:
From the balanced equation above,
2 moles of NBr3 reacted with 3 moles of NaOH.
Therefore, 40 moles of NBr3 will react with = (40 x 3)/2 = 60 moles of NaOH.
From the above calculations,
A higher amount of NaOH i.e 60 moles than what was given from the question i.e 48 moles is required to react completely with 40 moles of NBr3. Therefore, NaOH is the limiting reactant and NBr3 is the excess reactant.
A) each side of the equations is divided by the number of moles.
Answer:
Molar mass = 99 g/mol
Explanation:
Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2
The molar mass is given as the sum off the individual atomic mass of the elements in the compound.
Molar mass = C + O + 2Cl
Molar mass = 12 + 16 + 2(35.5)
Molar mass = 99 g/mol
