The amount of the solute is constant during dilution. So the mole number of HCl is 2*1.5=3 mole. The volume of HCl stock is 3/12=0.25 L. So using 0.25 L stock solution and dilute to 2.0 L.
Well. There is the color change and the formation of bubbles.
One of the two products of this reaction is carbonic acid (H2CO3), which immediately forms water and the gas you identified after exposure to the flaming and glowing splints. Write a balanced equation showing the decomposition of carbonic acid.
Answer: yes they are
Explanation:
because its so hot and the heat just stays at the bottom
90 degrees
As temperature increases, rate of reaction increases :)
