If there are 40 mol of NBr3 and 48 mol of NaOH, what is the excess reactant?
Nata [24]

Answer:

The correct answer is option B.

Explanation:

3NaOH+2NBr_3\rightarrow 3HOBr+3NaBr+N_2

Moles of NBr_3 = 40 mol

Moles of NaOH = 48 mol

According to reaction, 3 moles of NaOH reacts with 2 moles NBr_3

Then ,48 moles of NaOH will reacts with:

\frac{2}{3}\times 48 mol=32 mol of NBr_3

Then ,40 moles of NaBr_3 will reacts with:

\frac{3}{2}\times 40 mol=60 mol of NaOH

As we can see that 48 moles of sodium will completey react with 32 moles of nitrogen tribromide.

Moles left after reaction = 40 mol - 32 mol = 8 mol

Hence, the NBr_3 is an excessive reagent.

How many atoms are there in 144g of sucrose, C12H22O11 or sugar molecules?
kati45 [8]

Answer:

2.53×10²³ atoms

Explanation:

To solve this, convert grams to moles and moles to atoms.

To convert grams to moles, use the molar mass of C₁₂H₂₂O₁₁ (342.296 g/mol).  Divide the mass by the molar mass to get moles.  Moles = 0.4207

To convert moles to atoms, use Avogadro's number (6.022×10²³ atoms/mol).  Multiply moles by Avogadro's number to get atoms.  Atoms = 2.53×10²³
