Dispersion forces or London dispersion forces are collectively referred to as Van der Waals forces. These forces are temporary and arise from the relative position of electrons in one atom to another. If the electrons become distributed in an asymmetrical manner, the negative charge is concentrated at one end of the particle and a positive charge is concentrated at the other. These forces are also called induced dipole-induced dipole attraction.

If the freezing point of the solution had been incorrectly read 0.3 °C lower than the true freezing point, would the calculated
Dovator [93]

Answer : The molar mass of the solute would be low.

Explanation :

Formula used for depression in freezing point is:  

\Delta T_f=i\times K_f\times m\\\\T^o-T_s=i\times K_f\times\frac{w_b}{M_b}\times w_a}

where,

\Delta T_f = change in freezing point

\Delta T_s = freezing point of solution

\Delta T^o = freezing point of water

i = Van't Hoff factor

K_f = freezing point constant

m = molality

w_b = mass of solute

w_a = mass of solvent

M_b = molar mass of solute

From the formula we conclude that, when the freezing point of the solution read incorrectly that is freezing point of the solution is lower than the true freezing point then this means that change in freezing point would be high and the molar mass of the solute would be low.

Hence, the molar mass of the solute would be low.

1. Make an observation : My toaster doesn't toast my bread

2. Ask a question : Why doesn't my toaster work?

3. Form a hypothesis : My coffeemaker works when plugged into the outlet

4. Make a prediction : If something is wrong with the outlet, then my coffeemaker also won't work when  plugged into it

5. Conduct an experiment : I plug my coffeemaker into the outlet

6. Analyze the results : There is something wrong with the electrical outlet

Explanation:

The solution to the problem is as shown above.

  • A scientific method follow a methodical way of critically carrying out an inquiry into an observation.
  • Firstly, an observation is usually made with our senses. Here the researcher observes that the toaster does not toast his bread probably after a long wait.
  • He then proceeds to ask why the toaster does not work.
  • To investigate this, the forms a hypothesis. A hypothesis is a scientific guess. It is a tentative proposition about an investigation.
  • The researcher then makes a prediction about the outlet that might be faulty.
  • With this background, he goes on to carry out an experiment to substantiate his findings. This is seen when he plugs the coffeemaker into the outlet.
  • From the analysis of result, he sees that that something is wrong with the outlet.

A bottle of an unknown liquid has a volume of 6.3 mL and mass 255.15 g. What is its density? *
TEA [102]

Answer:

40.5 g/mL

Explanation:

Density is a measure of a substance's mass over its volume.

d = m/v

Therefore d = 255.15g/6.3mL = 40.5 g/mL
