<h2>
Answer</h2>
Atom: the basic unit of an element
Atomic theory of atoms: a theory that states that all matter is made of atoms that cannot be divided or destroyed
Element: a substance that cannot be broken down into a simpler substance
Gas: the state of matter that does not have a definite shape or a definite volume
Liquid: the state of matter that has an indefinite shape but a definite volume
Magnetic field: a region around a magnetic material or moving electric charge
Particle: a tiny piece of matter
Phase: a unique form of the existence of matter
Plasma: an ionized gas of positively and negatively charged particles
Scientific theory: an explanation for some naturally occurring event, developed from extensive observations, experimentation, and reasoning
Solid: the state of matter that has a definite shape and volume
Therefore, I hope this helps And Good Luck!
Answer:
C₂ = 0.056 ppm
Explanation:
Given data:
Initial volume = 2.0 mL
Initial concentration = 7.0 ppm
Final volume = 250.0 mL
Final concentration = ?
Solution:
Formula:
C₁V₁ = C₂V₂
C₁ = Initial concentration
V₁ = Initial volume
C₂ = Final concentration
V₂ = Final volume
Now we will put the values in formula.
C₁V₁ = C₂V₂
7.0 ppm × 2.0 mL = C₂ × 250.0 mL
C₂ = 14.0 ppm.mL /250.0 mL
C₂ = 0.056 ppm
Answer:
The process of dissolving can be endothermic (temperature goes down) or exothermic (temperature goes up).
When water dissolves a substance, the water molecules attract and “bond” to the particles (molecules or ions) of the substance causing the particles to separate from each other.
The “bond” that a water molecule makes is not a covalent or ionic bond. It is a strong attraction caused by water’s polarity.
It takes energy to break the bonds between the molecules or ions of the solute.
Energy is released when water molecules bond to the solute molecules or ions.
If it takes more energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes down (endothermic).
If it takes less energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes up (exothermic).
Explanation:
Answer:
- <u>Compressibility, expandibility, and density, are the most conspicuous properties of the gases explained by </u><em><u>the assumption that most of the volume in a gas is empty space.</u></em>
Explanation:
One of the assumptions of the kinetic molecular theory is that the gas particles are way smaller than the separtion between them and, in consequence, most of the volume in a gas is empty space.
This condition (that most of the volume in a gas is empty space) explains why the gases can be easily compressed: since there are vast unoccupied spaces when the pressure is increased, the particles can approach each other with which the total volume of the gas decreases.
Expandibility, the property of expanding, is the ability that gases have to occupy the entire space of the container in which they are located. The particles then will get separated leaving most of the space empty.
The fact that most of the volume in a gas is empty space means that the volume for a certain amount of particles is much larger than the volume that the same number of particles in a solid will occupy, driving to much lower densities.
