A chemical separation is a separation method that involves change in the chemical composition of one of the solutions that are to be separated in order to a new physical properties of one part reached leaving the rest alone.
For example, When we add a chemical to the solution that will precipitate only one part of the solution leaving the rest.
A physical separation is a separation in which solutions are separated on the basis of their physical properties.
For example, If we use physical separation method in separating two oils with different specific volumes then these two oils are separated on the basis of their settling.
yes because you have 2 H 2Na 2O on both sides
Going to different website and watching different science videos on the unit you are on
Hello!
The substances, ordered according to their dissolving time in water, are the following
Sugar Cubes > Granulated Sugar > Powdered Sugar
The difference between these substances is the degree of order. According to collision theory, for a substance to be dissolved, successful collisions between solvent molecules and solute molecules need to happen. as molecules are more ordered, successful collisions are less likely to happen, because atoms are fixed into a crystalline structure.
When the molecule is less ordered, successful collisions are more likely to occur, as the atoms can be impacted from different sides and aren't fixed into a given position.
As the degree of order increases, the dissolving time in water will be higher too, as more time would be required for successful collisions to happen. The most ordered substance is sugar cubes, followed by granulated sugar and powdered sugar, and that order is the same as the order for dissolving time.
Have a nice day!
