Chemistry

Cohesion – The attraction of water molecules to each other and creates high surface tension in water. An example of how it helps support life on Earth is that it allows insects to walk across the surface.

Adhesion – The attraction of water molecules to other substances and allows water to travel against gravity. An example of this is water moving up a tree even when there is gravity.

Specific heat capacity – the heat required to raise the temperature of the unit mass of a given substance by a given amount. An example of this is a swimming pool staying the same temperature no matter if it is hot or cold outside.

Expansion upon freezing – Water expands when its frozen which will keep it from sinking. Floating ice keeps the water underneath it warm. An example of this is an iceberg floating on top of a body of water.

Universal solvent – Can dissolve almost anything, usually water. An example is that water transports important chemicals or nutrients/minerals that is needed for all living organisms.

I just learned about this lol...

A solution of K2SO4 and KCl is added to a solution of Ba(NO3)2. Which of these compounds will precipitate out of this combined s
Archy [21]

A solution of K2SO4 and KCl is added to a solution of Ba(NO3)2. BaS0₄ (s) will precipitate out of this combined solution.

Molecular equation

K2SO4(aq) + Ba(NO3)2(aq)  → BaSO4(s) + 2 KNO3(aq)?

This equation represents a double displacement (replacement) reaction, also called a metathesis reaction, in which the reactant ions exchange places to form new products. The general equation is:

A-B + C-D → A-D + C-B;

where A and C are cations, and B and D are anions.

Complete ionic equation: Includes all ions and the precipitate.

2K^+(aq) + SO4^2-(aq) + Ba^2+(aq) + 2[NO3]^-(aq) → 2K^+(aq) + 2[NO3]^- + BaSO4(s)

In an aqueous solution, precipitation is the process of transforming a dissolved substance into an insoluble solid from a super-saturated solution.

The solid formed is called the precipitate. In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant.
