How does adding oxygen (o2) to this reaction change the equilibrium? 2so2(g) + o2(g) ⇌ 2so3(g) a. the equilibrium shifts right to produce more so3 molecules. b. the equilibrium shifts left to produce more o2 molecules. c. the equilibrium shifts right because of decreased collisions between so2 and o2 molecules. d. the equilibrium shifts left with an increase in so2 and o2 molecules. e. the equilibrium shifts left because of increased collisions between so2 and o2 molecules.

Based on Le Chatelier's principle, if the equilibrium of a given reaction is disturbed by external factors like temperature, pressure or concentration, then it will shift in a direction to undo the effects of the change produced.

The given reaction is:-

2SO2 (g) + O2(g)↔ 2SO3(g)

Thus, adding O2 will shift the equilibrium in a direction in which more of it will be consumed i.e. in the forward direction.

Ans A) The equilibrium will shift to the right to produce more SO3 molecules

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
