Answer:
Endothermic
Explanation:
This would be an endothermic reaction, due to the fact that the water would be signifigantly warmer then the ice cube, which causes it to melt.

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!

Answer:
B
Explanation:
A metathesis reaction is a reaction in which cations and anions change partners.
A general equation for a metathesis is
AX+CY→AY+CX, where A and C are cations, and X and Y are anions.
There are three possible products of a metathesis reaction.
A. an insoluble (solid) precipitate
B. water (from neutralization reaction)
C. an insoluble gas that bubbles out of solution
Metathesis reactions are also called double replacement reactions and double displacement reactions.
