8.5 The Combined Gas Law -- Part 4
A nurse must have a lot of knowledge about how the machine works to make sure it works correctly.
She is having treatment three times a week.
In a solution, identify the solute and solvent.
There are solutions around us.
Oxygen and nitrogen gases make up the majority of the air we breathe.
The ocean has many ionic compounds dissolved in water.
In your medicine cabinet, there is a solution of iodine dissolved in alcohol.
The solvent can be mixed in different proportions because it does not react with each other.
A solution of salt dissolved in water tastes salty.
The solution tastes very salty when a large amount of salt is dissolved.
In this case, salt is the substance present in the lesser amount, whereas the solvent is present in the greater amount.
The solute is salt and the solvent is water.
A solvent has at least one solute in it.
A solution of copper(II) sulfate forms as particles of solute dissolving, moving away from the crystal, and becoming evenly dispersed among the solvent (water) molecule.
Solids, liquids, or gases are known as solutes.
The solution has the same physical state as the solvent.
Sugar solution is liquid when sugar crystals are dissolved in water.
Water is the solvent and sugar is the solute.
Carbon dioxide gas is dissolved in water to make soda water and soft drinks.
The solute is the carbon dioxide gas, and the solution is water.
Water is a common solvent.
H bonds are polar.
The hydrogen atom has a partial positive charge and the oxygen atom has a partial negative charge.
The shape of a water molecule is not linear.
There are many hydrogen bonds that link water molecule together.
The properties of biological compounds are dependent on hydrogen bonds.
In water, hydrogen bonds form between the oxygen atom in one water molecule and the hydrogen atom in another.
A solution will be determined by the interactions between solute and solvent.
Energy is needed to separate the particles.
As solute particles move between solvent particles to form a solution, energy is released.
The energy for the initial separation must come from the attractions between the solute and solvent particles.
Between 1500 and 3000 mL of water is lost every day.
The majority of the body's water is contained in the cells of the kidneys, the skin, the lungs, and the gastrointestinal tract.
Dehydration can include the fluid in the tissue and the blood.
Between the loss of fluid can be fatal, these external fluids carry waste materials.
The intake of fluids replaces the water in the body.
The upper layer is less dense.
The two layers of water do not mix.
There are strong ionic bonds in NaCl.
The Ni tively charged Na+ ion and negatively charged Cl- ion is the ionic solute.
The 3)2 is found in the water of a polar solvent.
The attraction of the ion to other ion is diminished by the hydration of the ion.
The formula H2O over the arrow indicates that water is needed for the dissociation process but is not a reactant.
Ions on the surface of a crystal of NaCl are attracted to the polar water molecule that pulls them into solution.
The hydrogen bonds between the polar water and CH3OH form a solution.
Try Practice Problems 9.3 to 9.6 are nonpolar solutes.
Water and benzene are not polar solvent.
When FeSO4 and ionic solid LiBr are dissolved in water, describe the formation of a solution.
