The type of intermolecular force relates to the big difference in the electronegativities and is known as hydrogen bonding.
What are intermolecular forces?Intermolecular forces may be defined as the mechanism that mediates the interaction between the atoms of the molecules. It significantly includes the electromagnetic forces of attraction and repulsion between the atoms.
Some examples of intermolecular forces include London-dispersion force, dipole-dipole interaction, van der Waals interaction, hydrogen bonds, etc. Each one of them possesses a different set of characteristic properties distinctly. Some types of forces are also present in the body of living organisms.
Hydrogen bonding is a characteristic kind of interaction that remarkably includes dipole-dipole attraction between the most electronegative elements like Nitrogen, Oxygen, fluorine, etc., and the hydrogen atom.
Therefore, hydrogen bonding is a type of intermolecular force relates to the big difference in the electronegativities.

Write a summary on how to use a light microscope
DUE TODAY PLEASE HELP.
Answer:
Step 1: Connect the light microscope to a power source. If your microscope uses a mirror instead of an illuminator, you can skip this step. Instead, find a place where natural light is easily accessible
Step 2: Turn the revolving nosepiece so the lowest objective lens is in position.
Step 3: Mount your specimen onto the stage. But before doing so, see to it that your specimen is adequately protected by placing a coverslip on top of it.
Step 4: Use the metal clips to keep your slide in place. Make sure the specimen is positioned in the center, right under the lowest objective lens.
Step 5: Look into the eyepiece and slowly rotate the coarse adjustment knob to bring your specimen to focus. See to it that the slide does not touch the lens.
Step 6: Adjust the condenser for the maximum amount of light. Since you're on the low power objective, you may have to decrease the illumination. Use the diaphragm under the stage to adjust.
Step 7: Now slowly rotate the fine adjustment knob until you obtain a clearer image of your specimen.
Step 8: Examine your specimen.
Step 9: After you're done viewing with the lowest power objective, switch to the medium power objective and re-adjust the focus with the fine adjustment knob.
Step 10: Proceed to the high power objective once you have it focused.
Automobile catalytic Converters use a platinum callus to reduce air pollution by changing emissions such as carbon monoxide CO2 to carbon dioxide CO2 the uncatalyzed reaction is represented by the balance inflation below 2 CO + 02 2CO2 + heat determine the number of moles of O2 reaction with 28 moles of CO during this reaction
Answer:
14 mol O₂
Explanation:
The reaction between CO and O₂ is the following:
CO + O₂ → CO₂
We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:
2CO + O₂ → 2CO₂
As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:
28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂

What is an ecosystem?An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by action of microbes nutrients are released back in to the soil.

Describe what happens to the light ray when it travels through air then into water
Answer:
when light travels into the water from the air, it slows down (because water is a more dense substance) which causes it to change direction and makes it seem to bend. this is called refraction. mediums that are more dense have a higher refraction index. for example, air has a ri of 1, but water is about 1.33.

A chemist dilutes a 1.0 ml sample of 2.0M KNO₃ by adding water to it. If the concentration of the solution that is obtained is 0.0080 m, then its volume is 250mL.
How do we calculate volume?Volume for the given equation will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
M₁ = molarity of KNO₃ = 2M
V₁ = volume of KNO₃ = 1mL
M₂ = molarity of final solution = 0.0080M
V₂ = volume of final solution = ?
On putting these values on the above equation, we get
V₂ = (2)(1) / (0.0080) = 250mL
Hence option (2) is correct.
