Percent yield is 108.3%

<u>Explanation:</u>

Percent yield is the ratio of experimental yield and the theoretical yield multiplied by 100.The expression for the percent yield is given as,

Percent yield = $\frac{actual yield}{theoretical yield}\times100

It is given that the experimental or actual yield is 3.9 g and the theoretical yield calculated using stoichiometry is 3.6 g, then the percent yield is calculated as,

Percent yield = $\frac{3.9}{3.6}\times100 = 108.3

So the percent yield is 108.3%.

Which main intermolecular force must be overcome to sublime solid NH3?
lys-0071 [83]

Sublimation is the phase transition of a substance directly from the solid to the gaseous phase without passing through the liquid phase.

Here are the three forces that exist between two NH3 molecules:

1- Dispersion forces - these forces exist between ANY two molecules, regardless of anything else.

2- Dipole-dipole interactions - NH3 is a polar molecule with a permanent separation of charge. Each molecule behaves  like a tiny magnet and has + and - poles so 2 NH3 molecules attract each other. Dipole-dipole interactions are stronger than dispersion forces in small molecules.  

3- Hydrogen bonding - H is directly bonded to the extremely electro negative atoms N, O, or F, hence hydrogen atom is nearly stripped off electrons due to the large electro - negativity difference. Hydrogen being a small atom further reduces in size even allowing it to approach other molecules very closely. Here N,O,F gathers more partial negative charge.

Due to the close approach between the molecules and the strong partial charges, hydrogen bonding is generally more important than dipole-dipole interactions.

So the main intermolecular force must be hydrogen bonding.

What is the mass of a glucose solution that fills a 0.500-L intravenous bottle if the density of the glucose solution is
____ [38]

Answer:

m = 575 g

Explanation:

Given data:

Volume of solution = 0.500 L (0.500×1000 = 500 mL)

Density of glucose solution = 1.15 g/mL

Mass of glucose solution = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = velocity

Now we will put the values in formula.

1.15 g/mL = m/500 mL

m = 1.15 g/mL × 500 mL

m = 575 g

How many miles of a gas at 100 c does it take to fill a 1.00 l flask to a pressure of 152kPa
Hatshy [7]

The complete question is as follows: How many moles of a gas at 100 c does it take to fill a 1.00 l flask to a pressure of 152kPa

Answer: There are 0.0489 moles of a gas at 100^{o}C is required to fill a 1.00 l flask to a pressure of 152kPa.

Explanation:

Given: Volume = 1.00 L,    

Pressure = 152 kPa (1 kPa = 1000 Pa) = 152000 Pa

Convert Pa into atm as follows.

1 Pa = 9.86 \times 10^{-6} atm\\152000 Pa = 152000 \times \frac{9.86 \times 10^{-6}atm}{1 Pa}\\= 1.5 atm

Temperature = 100^{o}C = (100 + 273) K = 373 K

Using the ideal gas formula as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

PV = nRT\\1.5 atm \times 1.0 L = n \times 0.0821 L atm/mol K \times 373 K\\n = \frac{1.5 atm \times 1.0 L}{0.0821 L atm/mol K \times 373 K}\\n = 0.0489 mol

Thus, we can conclude that there are 0.0489 moles of a gas at 100^{o}C is required to fill a 1.00 l flask to a pressure of 152kPa.
