Summarize the feedback loop (transfer of energy) between the microbes and the mushrooms. (Video #1)
netineya [11]

Answer:

Cyanobacteria, Azotobactor and Azospirillum are the microbes which is required for nitrogen cycle.

Explanation:

Nitrogen Cycle is a type of cycle in which nitrogen moves from atmosphere to the earth surface and again return back to the atmosphere. Cyanobacteria, Azotobactor and Azospirillum are the microbes which is required for nitrogen cycle. If these microbes is vanished from the environment, the nitrogen cannot be converted into other forms. Carbon is present in the atmosphere in carbondioxide form. This CO2 is used by the plants from atmosphere and make food from it. When these plants are eaten by animals, this CO2 is again release in the atmosphere. Due to global warming, the microbes present in the soil die due to increase in temperature of the soil. Levels of CO2 and CH4 increases if the soil warms up.  With the increase in temperature, soil respiration increases which leads to more emission of CO2 and as a result more global warming occurs.

Explain in terms of atomic structure why the atomic radius of K is larger than that of Na
Lina20 [59]

Answer:

Potassium (K) has a larger average atomic radius (220 pm) than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, which means its valence electrons are further from the nucleus, giving potassium a larger atomic radius. The ionic radius increases in a particular group on moving from top to bottom due to increase in the principle energy shell though the number or electrons in the valence shell remain the same

A car battery produces electrical energy with the following chemical reaction.
jok3333 [9.3K]
It has a 1:2 ratio
If you look at the start of PbO2 it does not have a number so that is the one and if you look at 2H2O that has a 2 in front so that is where you get the 1:2 ratio

Please help<br><br> what are the 6 main points of the kinetic molecular theory
Darya [45]

Answer:The kinetic-molecular theory of gases assumes that ideal gas molecules (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) have an average kinetic energy proportional to the ideal gas's absolute temperature.
