A solution of 34% nacl is separated by a semipermeable membrane to a solution of 22% glucose. the membrane is only permeable to

Katyanochek1 [597]

The net osmosis will occur in the direction of the NaCl solution. This is because the solute concentration on that side is greater than that of the glucose solution. Osmosis is the process by which liquids move through semi permeable membrane from the region of lower concentration to the region of higher concentration.
Thus the water is going to move from the glucose solution into the NaCl solution.<span />

Consider the following reaction, equilibrium concentrations, and equilibrium constant at

REY [17]

Answer:

Equilibrium concentration of $H_{2}O$ is 12.5 M

Explanation:

Given reaction: $C_{2}H_{4}+H_{2}O\rightleftharpoons C_{2}H_{5}OH$

Here, $K_{c}=\frac{[C_{2}H_{5}OH]}{[C_{2}H_{4}][H_{2}O]}$

where $K_{c}$ represents equilibrium constant in terms of concentration and species inside third bracket represent equilibrium concentrations

Here, $[C_{2}H_{4}]=0.015M$ , $[C_{2}H_{5}OH]=1.69M$ and $K_{c}=9.0$

So, $[H_{2}O]=\frac{[C_{2}H_{5}OH]}{[C_{2}H_{4}]\times K_{c}}=\frac{1.69}{0.015\times 9.0}=12.5M$

Hence equilibrium concentration of $H_{2}O$ is 12.5 M

What do the elements within a "period" have in common? (pick one)

Gnesinka [82]

Answer:

All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
