Use the scenario to answer the following question. Four scientists observed an area of land that had been cleared of all trees a

nd bushes to make space for a power line. Each scientist had a different argument about the impact clearing this area of land might have on the bird population living in the ecosystem. Which scientist’s argument demonstrates how the ecosystem will MOST LIKELY be impacted? A. Scientist 4: The rate of erosion will decrease causing less food and shelter to be available to the birds. B. Scientist 1: The natural enemies of birds will be eliminated causing less food and shelter to be available to the birds. C. Scientist 2: Weather conditions may change causing less food and shelter to be available to the birds. D. Scientist 3: The population of trees in the environment will decrease causing less food and shelter to be available to the birds.

which resonance form would be the most stable contributor to the intermediate arenium ion produced by electrophilic bromination
valentinak56 [21]

The question is incomplete as the options are missing, however, the correct complete question is attached.

Answer:

The correct answer is option A. ( check image)

Explanation:

The most stable contributor to the intermediate arenium ion produced by electrophilic bromination of methoxybenzene in given options is option a due to the fact that this resonating form follows the octet rule is satisfied for all atoms and additional π bond is present in between C-O that makes it more stable, while in other options there are positive charge which means they do not follows octet rule completely.

Thus, the correct answer is option A. ( check image)

Sample of gas initially occupies 4.25 L at a pressure of 0.850 atm at 23.0°C. What will the volume be if the temperature is chan
Aliun [14]

Answer:  2.34 L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 0.850 atm

P_2 = final pressure of gas = 1.50 atm

V_1 = initial volume of gas = 4.25 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 23.0^oC=273+23.0=293.0K

T_2 = final temperature of gas = 11.5^oC=273+11.5=284.5K

Now put all the given values in the above equation, we get:

\frac{0.850\times 4.25}{293.0K}=\frac{1.50\times V_2}{284.5}

V_2=2.34L

Thus the final volume will be 2.34 L
