Which of the following best describes all reaction systems where Q < Kc ?Group of answer choicesThe system is not at equilibrium, and the reaction will go in the reverse direction. The system is not at equilibrium, and the reaction will go in the forward direction. The system is at equilibrium, and there are more reactants than products at equilibrium. The system will never be able to reach a state of equilibrium. The system is at equilibrium, and there are more products than reactants at equilibrium.

they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

can i get the brainiest answer

i answered it first

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
