Answer:

After 4 days 10 g will left

After 8 days 5 g will left.

Explanation:

Given data:

Half life of isotope = 4 days

Total amount of sample = 20 g

Amount left after each time period = ?

Solution:

The half life of radioactive isotope is 4 days it means after 4 days the amount left will be half of total amount.

20 g/2 = 10 g

The half amount which is left will be consume in next 4 days and remaining amount will be,

10 g/2 = 5 g

After 4 days 10 g will left

After 8 days 5 g will left.

If there are 40 mol of NBr3 and 48 mol of NaOH, what is the excess reactant
Vanyuwa [196]
<h3>Answer:</h3>

              Excess Reagent =  NBr₃

<h3>Solution:</h3>

The Balance Chemical Equation for the reaction of NBr₃ and NaOH is as follow,

                       2 NBr₃ + 3 NaOH   →   N₂ + 3 NaBr + 3 HBrO

Calculating the Limiting Reagent,

According to Balance equation,

               2 moles NBr₃ reacts with  =  3 moles of NaOH

So,

           40 moles of NBr₃ will react with  =  X moles of NaOH

Solving for X,

                       X  =  (40 mol × 3 mol) ÷ 2 mol

                       X  =  60 mol of NaOH

It means 40 moles of NBr₃ requires 60 moles of NaOH, while we are provided with 48 moles of NaOH which is Limited. Therefore, NaOH is the limiting reagent and will control the yield of products. And NBr₃ is in excess as some of it is left due to complete consumption of NaOH.
