Hope this helps

Explanation:

These are called quantum numbers: there are 4, but the first three are mainly used, only in orbital notation will you use all four.

The first is the electron's energy level or "shell", used as n. (Principle QN)

The second relates to the shape of the orbital and is used as l, when n and l are put together it defines the sublevel or subshell. (Angular Momentum QN)

The third one relates to the orientation of the electrons in that sublevel used as m(sub)l. (Magnetic QN)

The fourth one relates to the spin states of the electron, since they spin opposite directions, used as m(sub)s. (Electron Spin QN)

faust18 [17]

Answer: The approximate molecular mass of the polypeptide is 856 g/mol

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

$\pi=iMRT$

Or,

$\pi=i\times \frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution in L)}}\times RT$

where,

$\pi$ = osmotic pressure of the solution = 4.19 torr

i = Van't hoff factor = 1 (for non-electrolytes)

Mass of solute (polypeptide) = 0.327 g

Volume of solution = 1.70 L

R = Gas constant = $62.364\text{ L.torr }mol^{-1}K^{-1}$

T = temperature of the solution = $26^oC=[273+26]K=299K$

Putting values in above equation, we get:

$4.19torr=1\times \frac{0.327}{\text{Molar mass of solute}\times 1.70}\times 62.364\text{ L.mmHg }mol^{-1}K^{-1}\times 299K\\\\\text{molar mass of solute}=856g/mol$

Hence, the molar mass of the polypeptide is 856 g/mol

Setler79 [48]

Hey there Abigaildonaimor,

A cyclist rode at an average speed of 10mph for 15 miles. How long was the ride?

Answer:

Time = Distance / Rate
= 15 miles / 10mph
= 1.5 hours

Hope this helps :D

Think about what you've learned about how particle motion is related to temperature.

statuscvo [17]

Answer:

1& 4

Explanation:

1. The average kinetic energy of the particles in a substance determines the substance's temperature.

4. How fast a substance's particles are moving determines how hot or cold the substance is.

For a particular reaction, ΔH° is 34.2 kJ and ΔS is 99.2 J/K. Assuming these values change very little with temperature, over wh

Nostrana [21]

Over 344.76 K the forward reaction will be spontaneous

<u><em>calculation</em></u>

ΔG = ΔH° -TΔs

if ΔG =0

therefore 0 =ΔH°-TΔs

ΔH° = TΔs

divide both side by Δs

T = ΔH°/Δs

convert 34.2 kj into j

that is 1 kj = 1000 j

34.2 kj =? j

<em>by cross multiplication</em>

=[34.2 kj x 1000j / 1 kj] = 34200 j

T is therefore = 34200 j÷99.2 j/k =344.76 k

if T is greater than 344.76 k the forward reaction will be spontaneous

A rock weighing 75.0g is placed in a graduated cylinder displacing the volume from 31.4 ml to 36.5ml. What is the density of the

denis-greek [22]

Answer:

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

volume = final volume of water - initial volume of water

volume = 36.5 - 31.4 = 5.1 mL

But

1 mL = 1 cm³

5.1 mL = 5.1 cm³

From the question we have

$density = \frac{75}{5.1} \\ = 14.705882..$

We have the final answer as
