Answer:
Stomata
Explanation:
Normally stomata open when the light strikes the leaf in the morning and close during the night.
Answer:
A. Mantle
Explanation:
Mantle is the process that drives plate tetonics, thus being that layer of the Earth.
Answer:
high; low; energy.
Explanation:
Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.
This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.
During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.
In conclusion, increasing the surface area of a gas increases its collision rate and it's considered to be an evolutionary strategy that maximizes the diffusion of gas molecules because it catalyzes the rate of a gaseous reaction.
heat is a disgusting gacha heat...... joke
Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R)
Answer:
Sn^2+
Explanation:
A specie is diamagnetic if it has only paired electrons in its outermost shell. This implies that, we must first deduce the outermost electron configuration of the species. From that, we can now make our decision regarding which of the species is diamagnetic.
Bromine:
Electron configuration:
[Ar]4s2 3d10 4p5
Not diamagnetic
Chromium:
Electron configuration:
[Ar]4s1 3d5
Not diamagnetic
Phosphorus:
Electron configuration:
[Ne]3s2 3p3
Not diamagnetic
Tin II ion:
Electron configuration:
[Kr]4d10 5s2
Diamagnetic
