Explanation:
A process in which there occurs a decrease in concentration of solute particles upon addition of more amount of solvent is known as dilution.
Also, we know that molarity is the number of moles present in a liter of solution.
Mathematically, Molarity =
So, more is the volume of solution lesser will be the number of moles present in it. This means that when we increase the amount of solvent then there will be decrease in concentration of solute particles.
Thus, when 1.00 L of a solution of NaCl is diluted to 1.80 L then its molarity will decrease due to decrease in number of moles of NaCl.
Answer:
Silver
Explanation:
Given parameters:
Mass = 116g
Energy = 511J
Initial temperature = 21.6°C
Final temperature = 40.5°C
Unknown:
Specific heat capacity and the type of metal = ?
Solution:
To solve this problem, we need to find the specific heat capacity of the metal given,
H = m x c x Ф
H is the energy
m is the mass
c is the specific heat capacity
Ф is the change in temperature
511 = 116 x c x (40.5 - 21.6)
511 = 2192.4c
c = 0.233J/g°C
The specific heat capacity of silver is similar to this.
Answer:
C.
Explanation:
Sublimation occurs when a substance changes from a solid into a gas. Increases in temperature causes the kinetic energy of particles to also increase.
since you didn't have solid to gas as a option liquid was the obvious choice
