Zanzabum

Explanation:

A and D

A. A pressure equal to that of the osmotic pressure will result in reverse osmosis.

D. The movement of the solvent particles from the concentrated solution to the dilute solution is known as reverse osmosis.

During osmosis, water molecules from the less concentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.

Thus, the water passes through the membrane due to the difference in osmotic pressure/ solute concentration on either side of the membrane, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.  

Water potential equal to the pressure potential shifts  the equilibrium, resulting in the movement of solute.

<h3>                              φ= φs+φp</h3>

However, in reverse osmosis, solute molecules move from regions of high solute concentration, to regions of low solute concentration across the membrane.

What makes a metal and a non metal most
Katarina [22]

Answer:

Explanation:

The reactivity of elements in the periodic table is based on the number of electrons in there outermost shell. Elements (metals) that have few electrons in there outermost shell are highly reactive because it is easier to lose fewer number of electrons (in the outermost shell during a reaction) than to lose more electrons in the outermost shell - thus metals that have one electron in there outermost shell are most reactive and are more reactive than those that have two electrons in there outermost shell. Hence, metals in group 1 are the most reactive metals because they all have one electron in there outermost shell.

Non-metals that have fewer electrons to complete there octet configuration are highly reactive because it is easier to gain fewer number of electrons (in the outermost shell during a reaction) than to gain more number of electrons - thus nonmetals that have seven electrons in there outermost shell are more reactive than nonmetals that have six electrons in there outermost shell. Hence, nonmetals in group 17 are the most reactive nonmetals because they contain seven electrons and have just one electron left to complete there octet configuration.

Identify the following changes as physical or chemical. A loaf of risen but unbaked bread. Photo by Elinor D Bread dough rising:
sergey [27]

The answers include:

  • A loaf of risen but unbaked bread - chemical change.
  • Photo by Elinor D - chemical change.
  • Bread dough rising - chemical change.

<h3>What is a Chemical change?</h3>

This involves the formation of a new products from substances. In this scenario, a rising bread contains alcohol which evaporates.

Photographs also fall under this category and is therefore an irreversible chemical change.
