Explanation:
Membrane is a barrier that separates two phases and that totally or partially restricts the transport of one or more chemical species present in the phases. The membrane separation method is based on the use of chemical potential and/or electrical potential gradient as the driving force for the separation. The membrane separation unit operation is based on the use of chemical potential and/or electrical potential gradient as the driving force for the separation.
Given that chemical potential is a function of pressure, temperature and concentration, and that membrane separation processes are generally operated at a constant temperature, both concentration gradients and pressure gradients can act as driving forces capable of promoting the transport of a given species across the membrane.
Examples of processes where the driving force is the pressure gradient are: Microfiltration, Nanofiltration, and Reverse Osmosis. Processes where the driving force are the concentration gradient: gas permeation, dialysis. Processes whose driving force is the electric potential gradient: electrodialysis.
According to the kinetic molecular theory for an ideal gas, all gas particles "<span>have collisions that decrease the total energy of the system" but this is not always the case. </span>
Answer:
1.55 x 10²⁴ formula units
Explanation:
Given parameters:
Number of moles of CaCl₂ = 2.58moles
Unknown:
Formula units in the compound = ?
Solution:
To solve this problem, we must understand that;
1 mole of a substance contains 6.02 x 10²³ formula units
2.58 moles will contain 2.58 x 6.02 x 10²³ formula units
= 1.55 x 10²⁴ formula units
Given what we know about the forces that act upon objects, we can confirm that an object to which balanced forces are applied will not be in motion.
<h3>What are
balanced and
unbalanced forces?</h3>
- A balanced force is when an object is not in motion due to all forces being matched.
- This means that for every force, there is an opposite force of the same magnitude that nullifies it.
- When one of these forces increases and overtakes its opposite, we gain motion.
- When this happens, the forces are now unbalanced.
Therefore, we can confirm that since the forces that are acting on the object are balanced, meaning that each force is matched by an opposite force of the same magnitude, the object will not move. For this object to move, the forces would have to become unbalanced by increasing the magnitude of one.
