Option B, fragile, is the right answer.

The Permafrost soil (Gelisol) are found very harsh and cold weather such as Arctic and Antarctic. The Gelisol are simply corroded soils, fragile and their finding near the extreme ice covers presents them valuable indicators of the early symbols of global warming. Permafrost in these soils found within two meters of the surface of the soil.

Is the specimen classified as living or non-living? Use three pieces of evidence and reasoning to justify your answer. Provide 3
Anestetic [448]

Answer: All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun. All living things grow. Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured.  Chromists are a diverse group of plant-like organisms and range from very small to very large. They are found in almost all environments.                                            

Explanation: I hope that helped yall!

Which subatomic particle can change the molecular geometry of a molecule?
emmainna [20.7K]

Answer:

Electrons

Explanation:

According to the Valence Shell Electron Pair Repulsion Theory (VSEPR), the geometry of a molecule depends on the number of electron pairs (regions of electron density) on the central atom of the molecule. Electron pairs on the valence shell of the molecule tend to position themselves as far apart in space as possible to minimize repulsion between them. Hence, the orientation of these electron pairs is the ultimate determinant of the observed geometry of a molecule.

Lone pairs of electrons cause more repulsion than bond pairs of electrons on the central atom of a molecule. Hence when the central atom of a molecule contains lone pairs of electrons, the molecular geometry is usually distorted from the expected geometry on the basis of VSEPR theory.

Hence, electrons are the subatomic particles which are responsible for any change in the observed molecular geometry of a molecule.

What is the ΔG for the following reaction at 25°C?
ikadub [295]
\Delta G_{global}=\Delta G_{products}-\Delta G_{reagents}\\\\
\text{We should consider the stoichiometry:}\\\\
\Delta G=2\Delta G_{NO_2}-\Delta G_{N_2O_4}\\\\
\Delta G=2\cdot51.8-98.28=103.6-98.28\\\\
\boxed{\Delta G=5.32~kJ}

Concerning Boyle's Law, if you had a gas at a pressure of 101 kPa and decreased the volume of the container holding the gas to o
Viefleur [7K]

Answer:

P_2=404 kPa

Explanation:

Hello,

In this case, the Boyle's is mathematically defined via:

P_1V_1=P_2V_2

Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:

V_2=\frac{1}{4} V_1

We can compute the new pressure:

P_2=\frac{P_1V_1}{V_2} =\frac{P_1V_1}{\frac{1}{4} V_1} =\frac{101kPa*V_1}{\frac{1}{4} V_1} \\\\P_2=4*101kPa\\\\\\P_2=404 kPa

Which means the pressure is increased by a factor of four.

Regards.
