Answer:
c2h4 (etthane........
bexcuse it has 6 bond of hydrogen
The equilibrium constant of a reaction is defined as the ratio of the concentrations of the products over the reactants.
I'm sorry if this does not answer your question, although I tried my best.
Answer is: the molarity of a solution of HF is 0.73 M.
n(HF) = 4.400 mol; amount of hydrofluoric acid.
V(HF) = 6.00 l; volume of hydrofluoric acid.
c(HF) = n(HF) ÷ V(HF).
c(HF) = 4.400 mol ÷ 6.00 l.
c(HF) = 0.733 mol/l; molarity of a solution (hydrofluoric acid).
Chemical changes: A substance is chemically changed due to a chemical reaction, and forms a new substance and energy that is given off or absorbed.
Examples:
Paper burned
Souring milk
Baking a cake
Rusted iron
Physical change: Substance that doesn't change what the substance is.
Examples:
Paper cut in half
Water boiled
Molded bread
Ice melted into a liquid
