Answer:
C) Q < K, reaction will make more products
Explanation:
- 1/8 S8(s) + 3 F2(g) ↔ SF6(g)
∴ Kc = 0.425 = [ SF6 ] / [ F2 ]³
∴ Q = [ SF6 ] / [ F2 ]³
∴ [ SF6 ] = 2 mol/L
∴ [ F2 ] = 2 mol/L
⇒ Q = ( 2 ) / ( 2³)
⇒ Q = 0.25
⇒ Q < K, reaction will make more products
An ecosystem is simply a collection of communities of plants, animals, and microbes interacting together and with their physical environments.
<h3>Energy flow in an ecosystem</h3>
Energy enters the ecosystem through a group of living organisms known as the producers. the producers are mainly the green plants that are capable of photosynthesizing.
Photosynthesis converts solar radiation from the sun to chemical energy in green plants. Another group of organisms in the ecosystem, the primary consumers, feed directly on the producers and as such, are able to gain some energy from them.
The secondary consumers obtain their own energy by feeding on primary consumers. Tertiary consumers feed on the secondary consumers for their own energy and the food chain goes on and on.
Only about 10% of the available energy in one trophic level goes to the next trophic level. The rest of the energy is lost as heat to the surroundings. Thus, the producers have the highest energy in the ecosystem while organisms at the top of the food chain have the lowest energy.

There is 6.02*10^23 molecule per mole. And there is 2 atoms per oxygen molecule. So the answer is 1.204*10^24 atoms in 1.0 mole of O2.
Answer:
Fluorine, oxygen, or nitrogen
Explanation:
<u>Hydrogen bridge bond</u>: It is an attraction that exists between a hydrogen atom (positive charge) with a very electronegative small atom, such as fluorine (F), oxygen (O) or nitrogen (N) (FH, OH, NH), which It has a pair of free electrons (negative charge), hence the name "hydrogen bond", which should not be confused with a covalent bond to hydrogen atoms). A hydrogen bridge is actually a dipole-dipole attraction between molecules that contain these three types of polar junctions.
This type of attraction has only a third of the strength of covalent bonds, but it has important effects on the properties of the substances in which they occur, especially in terms of melting and boiling points in crystal structures.
