Answer:

Are sorbents good for the environment?

Natural Inorganic Sorbents

Second, sorbents that sink should not be used as they could be harmful to the environment. Sinking is a problem with many sorbents, such as untreated peat moss, most inorganic sorbents, and many wood products.

Its major result is to clean out some surface contaminants, which makes it simpler for oil to absorb. On the other hand, pyrolysis, a high-temperature thermal treatment, causes the sorbent to carbonise. In turn, this greatly improves the oil sorption capacity and oil to water selectivity.

When recovering adsorbent materials that cause secondary contamination, lighter, less viscous oil is lost through the pores more readily than heavier, more viscous oils. Application is simple because sorbents can be applied automatically or manually to spills using blowers or fans.

The best sorbents for recovering oil are typically synthetic ones. In some circumstances, a weight ratio of 40:1 for oil to sorbent can be reached, as opposed to 10:1 for organic compounds and only 2:1 for inorganic materials.

A substance used to absorb or adsorb liquids or gases is known as a sorbent. Examples comprise: a substance that works via adsorption and is comparable to molecular sieve material (attracting molecules to its surface). It has strong thermal conductivity and a big interior surface area.

Thus, On the other hand, pyrolysis, a high-temperature thermal treatment, causes the sorbent to carbonise.

Explanation:

Based on the illustration, the statement that best explains why the Scotch broom is able to outcompete the native plants in the area would be the specialized seed pods that allow seeds to be dispersed farther and into the less crowded areas.

Different organisms have different ways of behaving to ensure the survival of their propagules or offsprings.

In the case of the Scotch broom, the ability of the pods holding the seeds to burst open and catapult the seeds far away from the parent plant is a reproductive strategy to ensure that their seeds are well dispersed.

By doing so, the propagules of the plant will reach new areas where they do not exist before and as such, able to spread quite quicker than the native plants.

The molarity of the 500 mL KOH solution needed to neutralize the 40 mL of 2.50 M HCl is 0.2 M

HCl + KOH —> KCl + H₂O

From the balanced equation above,

The mole ratio of the acid, HCl (nA) = 1

The mole ratio of the base, KOH (nB) = 1

MaVa / MbVb = nA / nB

(2.5 × 40) / (0.15 × Vb) = 1

100 / (Mb × 500) = 1

Cross multiply

Mb × 500 = 100

Divide both side by 500

Mb = 100 / 500

Mb = 0.2 M

Thus, the molarity of the KOH solution needed is 0.2 M

Here are three types of probes that land on space physically. Interplantery, orbiters, and landers.

Explanation:

These are the ones that collect data and other stuff from space.

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.

In a reaction involving sodium metal and chlorine gas, the amount of sodium metal required to react with 0.950 grams of chlorine gas would be 0.62 grams

From the balanced equation of the reaction:

2Na (s) + Cl2 (g) ---------> 2NaCl (s)

The mole ratio of Na to Cl2 is 2:1.

Mole of 0.950 grams of chlorine gas = 0.950/70.906

                                                             = 0.0134 moles

Equivalent mole of Na = 0.0134 x 2 = 0.0268 moles

Mass of 0.0268 moles Na = 0.0268 x 22.99

                                           = 0.62 grams

A small sample of methane burns, releasing 120.0 kJ of heat and doing 830.0 kJ of work. The total energy released is -950.0 kJ.

Energy is a property that is transferred to a physical system, recognizable in the performance of work and in the form of heat and light.

A small sample of methane undergoes combustion. As the hot gas mixture expands, it releases energy (E).

The change in the energy is the sum of the heat released and the work done.

ΔE = q + w = -120.0 kJ + (-830.0 kJ) = -950.0 kJ

Explanation:

A1)      When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO).

A2)      magnesium oxide

A3)      Do not return chemicals to their original packaging. An incompatible mixture may accidentally be formed.

Keep chemical containers closed. Dust and vapour may escape from an open container, while gases and suspended material may penetrate this, causing the nature of the chemical to change. This will also avoid unnecessary exposure.

Never use a wrong or an unmarked reagent. If you are unsure about the compound, do not use it. Instead, have it disposed of (see Disposal of Hazardous Waste).

Never put spatulas, stirrers or other objects into a storage container for chemicals. Remove the contents by pouring and rolling the contents of the glass into a beaker, glass container or other suitable equipment. Spatulas may be used with caution in laboratory reagent containers. Remember the labelling (see the Safety Rules for working in lab).

Once removed from the bottle or glass, cork stoppers must be placed on a clean surface (e.g. a watch glass or other suitable equipment) with the opening facing down. This is to avoid contamination of the compound and unnecessary exposure.

Chemical bottles must not be carried by the neck of the bottle, nor next to your body. Suitable carrying arrangements should be employed, e.g. buckets or trolleys.

When pouring from bottles, the label should always face upward to prevent any spillage from destroying the label.

Never put any chemicals in the bottle other than the one indicated on the label.

Special precautions should be taken when handling concentrated acids. Dilution of acids should be performed by pouring the acid into water and stirring continuously.

The type of intermolecular force relates to the big difference in the electronegativities and is known as hydrogen bonding.

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.
