Use the equation to answer the question. H2O(l) + heat ⇄ H2O(g)
A sample of water is at equilibrium at 100°C. Which statement best describes what will happen if liquid water is added to the system?

-More liquid water molecules will change to water vapor until a new equilibrium is reached.
-All of the liquid water molecules that are added will become water vapor.
-More water vapor molecules will change to liquid water until a new equilibrium is reached.
-All of the liquid water molecules that are added will remain liquid water.

I need help on this quick check ASAP!

A: More liquid water molecules will change to water vapor until a new equilibrium is reached.

Explanation:

I'm not good at explaining but I took the quick check and this answer was correct b)

- 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

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
