Explanation:
because metal want to give electron and nonmetal want to gain.
A or D I think...sorry if it’s wrong
(10)an object will continue to travel at a constant speed unless acted by an unbalanced force according to newtons second law every force acted on a body has a equal and opposite reaction so the speed and the direction of the object will change.
(9) balanced force (i think so )
hope this is what you needed the 10th one is for understanding you can shorten it after reading and i think what i have written is not wrong :P:P:P;p:P:):):):D=) for the ninth one i am not sure but i think so :P:)=)
Answer:
Kc = [C2H5OH]/{[C2H4][H2O]}
[H2O] = [C2H5OH]/{[C2H4] x Kc}
[H2O] = 1.69/(0.015 x 9.0 x 10^3) = 0.013 M
Explanation:
Kc is the equilibrium constant, it is egal to the product of the equilibrium concentration of the product dived by the product of the equilibrium concentration of the reactants.
with that formula and what is given, male the equilibrium concentration of H2O the subject of the formula and calculate its concentration by substituting given values.
