The Scotch broom is an invasive species in California, Oregon and Washington. These shrubs grow quickly after areas that have been cleared of
trees and inhibit reforestation by out-competing native seedling trees. These plants developed a mutation that causes their seed to burst from
their shell when touched by passing animals. As animals brush past these plants, the black dried pods of the Scotch broom explode with a sharp
pop, scattering seeds away from the parent plant.
Which statement below best explains why the Scotch broom is able to out-compete the native plants in that area?
A. Relying on animals to disperse the seeds always results in better reproductive success than other methods of seed dispersion.
B. Specialized seed pods allow seeds to be dispersed farther and into less crowded areas promoting reproductive success.
C. The crackling sound of seed pods exploding promotes reproductive success by attracting the animals that are responsible for scattering
seeds.
D. Genetic mutations have caused the plant to be more resistant to cold temperatures allowing them to survive and reproduce all year
long.
Answers
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.
Reproductive successDifferent 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.

How many grams of sodium metal is required to react with 0.950 grams of chlorine gas?
Answers
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
Stoichiometric calculationFrom 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

What is energy?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).
It releases 120.0 kJ of heat. By convention, when heat is released, we assign it a negative sign. Thus, q = -120.0 kJ.It does 830.0 kJ of work. By convention, when the system does work on the surroundings, we assign it a negative sign. Thus, w = -830.0 kJ.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

Answer:
MAKE ME BRAINLIEST TOOK TIME!!!!
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.

How may using sorbents to clean an oil spill be helpful to the ecosystem?
Answers
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.
What are the advantages of using sorbents?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.

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.
If 40mL of 2.50M HCl neutralizes 500ml. of KOH, what is the molarity of the KOH?
Answers
The molarity of the 500 mL KOH solution needed to neutralize the 40 mL of 2.50 M HCl is 0.2 M
Balanced equationHCl + 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
How to determine the molarity of KOH Volume of acid, HCl (Va) = 40 mLMolarity of acid, HCl (Ma) = 2.5 MVolume of base, KOH (Vb) = 500 mL Molarity of base, KOH (Mb) =?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
