Diagram 1 exhibits the nature of the particles within the state that forms after a solid melts. Solids melt into liquids and the particles within a liquid have a greater spacing than the particles in a solid. Moreover, these particles are free to slip over one another, which means that liquids do not have a definite shape; however, the particles are still confined in by intermolecular forces, which means that the volume of a liquid is definite.
Answer:
The molar mass of the gas
Explanation:
The ideal gas equation of state is:
PV = nRT
If we measure the volume (V), the pressure (P), and the temperature (T), we use the gas constant R (0.082 L.atm/K.mol) to calculate n (moles of gas):
n = PV/RT
Then, we can divide the mass into the number of moles to calculate the molar mass of the gas:
molar mass = mass/n
Answer:
Option-D (Piece of Wood) is the correct answer.
Explanation:
Density is related to mass and volume as,
Density = Mass / Volume
For Wood,
Density = 42.5 / 50
Density = 0.85
You can calculate remaining densities by yourself. Among all the density of Piece of Wood is the least.
<h3><u>Answer;</u></h3>
the ions dissociate from each other in solution and are free to move independently
<h3><u>Explanation;</u></h3>
- <em><u>All soluble ionic compounds are strong electrolytes. They conduct very well because they provide a plentiful supply of ions in solution. That is; they mostly break up into ions as they dissolve in water</u></em>.
- An electrolyte solution conducts electricity because of the movement of ions in the solution.
- Ionic compounds have ions that are electrically charged to conduct electricity in liquid state or in aqueous solutions.
