(57.0 g B2O3 / (69.6202 g B2O3/mol) x (4mol BCI3 / 2 mol B2O3) = 1.64 mol BC13

(44.7 g C12) / (70.9064 g C12/mol) x (4mol BCI3 / 6mol C12) = 0.42027 mol BC13

(68.8 g C) / (12.01078 G C/mol) x (4mol BCI3 / 3 mol C) = 7.63 mol BCI3

C12 is the limiting reactant.

(0.42027 mol BCI3) X (117 . 170 g BCI3/mol) = 49.2 g BCI3 in theory.

statuscvo [17]

Answer:

(a) The lewis structure for methylisocyanate is in the attached.

(b) The carbonyl carbon have an sp² hybridization

(c) The nitrogen have an sp² hybridization?

Explanation:

(a) The lewis structure for methylisocyanate has the nitrogen with one lone pair and the oxygen with two lone pairs.

(b) The carbonyl carbon form double bond with the oxygen causing to form three hybrid orbitals sp².

The Nitrogen also forms a double bond with the carbon having an sp² hybridization too.

Answer : The mass of nitric acid is, 214.234 grams.

Solution : Given,

Moles of nitric acid = 3.4 moles

Molar mass of nitric acid = 63.01 g/mole

Formula used :

\text{Mass of }HNO_3=\text{Moles of }HNO_3\times \text{Molar mass of }HNO_3

Now put all the given values in this formula, we get the mass of nitric acid.

\text{Mass of }HNO_3=(3.4moles)\times (63..01g/mole)=214.234g

Therefore, the mass of nitric acid is, 214.234 grams.
