Answer:
Explanation:
Ba( OH)₂ + 2HCl = BaCl₂ + 2H₂O .
75.5 mL of 0.247 M barium hydroxide = .0755 x .247 = .01864 moles
95.0 mL of 0.330 M HCl = .095 x .33 = .03135 moles
mole ratio of hydrochloric acid to barium hydroxide
= .03135 / .01864 = 1.68
theoretical ratio = 2 /1 = 2
As the theoretical ratio is more , therefore HCl is the limiting reactant .
Answer:
Surely with water
Ok, but how?
There are many Hydrogen Bond between H2O moleculs and london bonds. When fishes take water with their gill,they are broke london bonds. And they can take their needs, Oxygen. Only this.
Good luck :D
D. metamorphic rock melts and crystallizes to become igneous rock <span />
Answer:
Explanation:
When something is burned, it means that it is <u>reacted with oxygen</u>. Steel wool is made out of iron, which bonds with oxygen atoms to form iron oxide which is solid in this reaction. Since, there are now more solid atoms in the steel wool, it will weigh more than before it was burned.
Hope this helped!
