) If you started with 2.3182 g of 3-nitrophthalic acid and had a 93% yield of 3-nitrophthalhydrazide, how many grams of 3-nitrop

MArishka [77]

Answer: 1.8124 g of 3-nitrophthalhydrazide were recovered.

Explanation:

The balanced chemical reaction will be :

$C_8H_5NO_6+N_2H_4\rightarrow C_8H_5N_3O_4+2H_2O$

moles of 3-nitrophthalic acid = $\frac{\text {given mass}}{\text {molar mass}}=\frac{2.3182g}{211.13g/mol}=0.0110mol$

As 1 mole of 3-nitrophthalic acid gives = 1 mole of 3-nitrophthalhydrazide

0.0110 moles of 3-nitrophthalic acid gives = $\frac{1}{1}\times 0.0110=0.0110$ mole of 3-nitrophthalhydrazide

mass of 3-nitrophthalhydrazide = $moles\times {\text {molar mass}}=0.0110mol\times 177.16g/mol=1.9488g$

As the percentage yield is 93% , the mass of 3-nitrophthalhydrazide recovered = $\frac{1.9488\times 93}{100}=1.8124g$

Therefore 1.8124 g of 3-nitrophthalhydrazide were recovered.

A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5 m/s^2 what is the mass of the bowling ball?

Kruka [31]

Data:

F (force) = 22.0 N

m (mass) = ? (in Kg)

a (acceleration) = 5.5 m/s²

We apply the data to the Resultant Force formula, we have:

4.0 kg

I hope this helps. =)

A military jet cruising at an altitude of 12.0km and speed of 1300./kmh burns fuel at the rate of 46.2/Lmin. How would you calcu

ira [324]

Answer:

2,452.12 L of fuel the jet consumes on a 1150 km mission.

Explanation:

Speed of the jet = 1300 km/h

1 hour = 60 minutes

$1300 km/h=\frac{1300 km}{60 min}=21.667 km/min$

Rate at which jet consumes fuel = 46.2 L/min

Distance covered by jet by consuming 1 liter fuel or mileage = R

R = $\frac{21.667 km/min}{46.2 L/min}=0.4690 km/L$

The amount of fuel the jet consumes on a 1150 km mission will = V

Amount of fuel = $\frac{Distance}{Mileage}$

$V=\frac{1150 km}{0.4690 km/L}=2,452.12 L$

2,452.12 L of fuel the jet consumes on a 1150 km mission.
