Answer:
100 mL is the volume of HCl needed to neutralize the 44.3 of Ba(OH)₂
Explanation:
This is the chemical equation:
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Formula for neutralization is:
Molarity of acid . Volume of acid = Molarity of base . Volume of base
0.121 . Volume of acid = 0.274 . 44.3
Volume of acid = (0.274 . 44.3) / 0.121 → 100
Answer:
In the chemical bonds.
Explanation:
There are different types of chemical bonds, some store a TON of energy while others do not store as much. You can think of it like this: for bonds with low energy, it takes a LOT of force to pull them apart, meaning they are strong bonds. However, this way, you have to put energy into them to break the bonds and form a chemical reaction. This is an endothermic reaction, a reaction that absorbs heat from its surroundings.
Instead, bonds in exothermic reactions are BEGGING to form a more stable bond, and hence store a lot of potential energy. Due to the difficulty of maintaining these bonds, there is a lot of energy put into them. If you break them, however, (exothermic reaction) the energy is released, and hence the exothermic reaction happens.
