What is the Lewis dot diagram structure for PI2F
Brut [27]

Answer:

Please find attached the completed Lewis dot diagram structure for PI₂F

Explanation:

The number of valence electrons are;

Phosphorus = 5 Electrons

Iodine = 2 × 7 electrons = 14 electrons

Chlorine = 7 electrons

The total number of valence electrons = 14 + 7 + 5 = 26 electrons

2) We draw the symbol that represents the basic (general) structure of the molecule as follows;

The sheared electron pair are represented by single bond lines

3) We complete the octet structures round the fluorine and the iodine atoms as attached showing 18 electrons plus 6 shared electron pairs, with a maximum from step 2 to give a total of (18 + 6) 24 electron pairs

4) We add the 2 unaccounted valence electron on the phosphorus atom to give it the stable octet structure, which gives the completed Lewis structure

In the balanced reaction below, what is the mole ratio comparing iron (Fe) and oxygen gas (O2)?
zepelin [54]

The given balanced reaction is,

4Fe(s) + 3O_{2}(g) --->2Fe_{2}O_{3} (s)

The stoichiometric coefficients of each element or compound represents the number of moles of that element or compound required for the complete reaction to take place.

The mole ratios of different products and reactants will be:

\frac{Fe}{O_{2}} = \frac{4 mol Fe}{3 mol O_{2}}

\frac{Fe}{Fe_{2}O_{3}} = \frac{4 mol Fe}{2 Fe_{2}O_{3}}

\frac{O_{2}}{Fe_{2}O_{3}} =\frac{3 mol O_{2}}{2molFe_{2}O_{3}}

So the mole ratio comparing iron (Fe) and oxygen gas (O_{2}) is

4 : 3

The actual yield of a certain reaction is 34.0 g, while the theoretical yield is 50.0 g. Calculate the percent yield.
anyanavicka [17]
The percent yield formula is % yield= (actual yield/theoretical yield) x 100 
34.0g/50.0g= .68 x 100 = 68.0% (theres three sig. figs.)
