When cool, dense air from over the water flows inland, it's called a sea breeze.
God bless!
A.) Phosphate ion or Orthophosphate
d.) Hydroxide
D.) Ammonium
e.) Iron
C.) Nitrate
f.) Sulfur dioxide
Answer:
Both are endothermic reactions.
Explanation:
Chemical equation:
1/2H₂(g) + 1/2I₂(g) → HI(g) + 6.2 kcal/mol
Chemical equation:
21.0 kcal/mol + C(s) + 2S(s) → CS₂
Both reaction are endothermic because heat is added in both of reactions.
Endothermic reactions:
The type of reactions in which energy is absorbed are called endothermic reactions.
In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.
For example:
C + H₂O → CO + H₂
ΔH = +131 kj/mol
it can be written as,
C + H₂O + 131 kj/mol → CO + H₂
Exothermic reaction:
The type of reactions in which energy is released are called exothermic reactions.
In this type of reaction energy needed to break the bonds are less than the energy released during the bond formation.
For example:
Chemical equation:
C + O₂ → CO₂
ΔH = -393 Kj/mol
it can be written as,
C + O₂ → CO₂ + 393 Kj/mol
Answer:
The correct answer is a. Hydrogen bonding.
Explanation:
The property by which water molecules attract each other is cohesion. groups of water molecules are formed by this interaction by adhesion with other water molecules.
Hydrogen bridges are great forces that hold water molecules together. They form a compact structure that gives it the property of being an almost incompressible liquid. These weak interactions are formed between a hydrogen with a positive partial charge and a more electronegative atom, such as oxygen.
Have a nice day!
