Consider the chemical system co + cl2 cocl2; k = 4.6 ? 109 l/mol. 2. how do the equilibrium concentrations of the reactants compare to the equilibrium concentration of the product?
a. they are much smaller.
b. they are much bigger.
c. they are about the same.
d. they have to be exactly equal.
e. you can't tell from the information given.

- 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

idk what is it? is this a question that you know the answer or u dont
