Grignard reactions are highly exothermic and are performed in ether solvent. There is a real risk of fire during this reaction.
AleksAgata [21]

Answer:

Ideally, extinguish the flames with a glass watch or beaker.

Explanation:

When you cover the distillation equipment with a watch glass or beaker, you reduce the oxygen content and it is completely eliminated thanks to the fire itself that consumes it. Once there is no more oxygen the fire is extinguished and it should take no more than 2 or 3 seconds to occur this situation

It is the easiest and most careful way to extinguish the fire during the Grignard reaction

During the chemical reaction given below 21.71 grams of each reagent were allowed to react. Determine how many grams of the exce
swat32

Answer: 16.32 g of O_2 as excess reagent are left.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} SO_2=\frac{21.71g}{64g/mol}=0.34mol

\text{Moles of} O_2=\frac{21.71g}{32g/mol}=0.68mol

2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)  

According to stoichiometry :

2 moles of SO_2 require = 1 mole of O_2

Thus 0.34 moles of SO_2 will require=\frac{1}{2}\times 0.34=0.17moles  of O_2

Thus SO_2 is the limiting reagent as it limits the formation of product and O_2 is the excess reagent.

Moles of O_2 left = (0.68-0.17) mol = 0.51 mol

Mass of O_2=moles\times {\text {Molar mass}}=0.51moles\times 32g/mol=16.32g

Thus 16.32 g of O_2 as excess reagent are left.

What is the molarity of a solution composed
Neporo4naja [7]

Answer:

0.0845 M

Explanation:

First we <u>convert 4.27 grams of potassium iodide into moles</u>, using its <em>molar mass</em>:

  • Molar Mass of KI = 166 g/mol
  • 4.27 g ÷ 166 g/mol = 0.0257 mol

Now we <u>calculate the molarity of the solution</u>, using <em>the number of moles and the given volume</em>:

  • Molarity = moles / liters
  • Molarity = 0.0257 mol / 0.304 L = 0.0845 M
