Answer:
Given - acc = 4 m/ s^2
Force = 255 N
To find = mass
Solution -
Using the formula,
255 = Mass × 4
255 /4 = Mass
63.75 = Mass
1 N = kg m/s^2
63.75 kg = Mass
Solution A contains 5 molecules of albumin (protein) and solution B contains 12 molecules of glucose. The solutions are separate
d by a membrane. What way will water move? A. water will move from solution B to solution A because albumin is larger in size B. ]water will move from solution B to solution A because albumin is in lower concentration C. water will move from solution A to solution B because glucose is in higher concentrations D. water will move from solution A to solution B because glucose is smaller in size
1 answer:
Answer:
C. Water will move from solution A to solution B because glucose is in higher concentration.
Explanation:
In osmosis, the molecules of solvent will pass through a semipermeable membrane from a less concentrated to a more concentrated solution.
Solution B is more concentrated, so the water will move from A to B.
A and D are wrong, because the size of the solute particles does not control the direction of osmosis.
B is wrong because water moves to the more concentrated solution.

Answer : The balanced reduction half-reaction is:
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
The given balanced redox reaction is :
The half oxidation-reduction reactions are:
Oxidation reaction :
Reduction reaction :
In order to balance the electrons, we multiply the oxidation reaction by 2 and reduction reaction by 3 and then added both equation, we get the balanced redox reaction.
Oxidation reaction :
Reduction reaction :
The balanced redox reaction will be:
Thus, the balanced reduction half-reaction is:
Answer:
E. 8.08 x 10⁴.
Explanation:
Hello,
In this case, for the reaction:
We can compute the Gibbs free energy of reaction via:
Since both the entropy and enthalpy of reaction are given at 298 K (standard temperature), therefore:
Then, as the equilibrium constant is computed as:
We obtain:
For which the answer is E. 8.08 x 10⁴.
