Answer: The correct answer is Option c.

Explanation: There are 2 types of planets in Our Solar system:

1. Inner planets: There are 4 planets which are known as inner planets which are Mercury, Venus, Earth and Mars. These 4 planets lie close to Sun. These planets have rocky surfaces and have no ring system in them. The maximum number of moons in inner planets are 2. The orbital time of these planets is less than the outer planets.

2. Outer planets: There are 4 planets which are known as inner planets which are Jupiter, Saturn, Uranus and Neptune. These 4 planets lie far from the Sun. These planets have gaseous surfaces and have ring system in them. These planets have many number of moons as compared to the inner planets. The orbital time of these planets is more than the inner planets.

From the above information, the correct answer is option c.

Use the Nernst equation to calculate the concentration of the unknown solution. Base this on your experimental voltage of 1.074

Hoochie [10]

Answer:

0.3793 M

Explanation:

The unknown metal is zinc. So the equation of the reaction is;

Zn(s) + Cu^2+(aq) -------> Zn^2+(aq) + Cu(s)

From Nernst equation;

E = E° - 0.0592/n log Q

[Cu2+] = 0.050179 M

n = 2

[Zn^2+] = ?

E = 1.074 V

E° = 0.34 - (-0.76) = 1.1 V

Substituting values;

1.074 = 1.1 - 0.0592/2 log [Zn^2+]/0.050179

1.074 - 1.1 = - 0.0592/2 log [Zn^2+]/0.050179

-0.026 = -0.0296 log [Zn^2+]/0.050179

-0.026/-0.0296 = log [Zn^2+]/0.050179

0.8784 =log [Zn^2+]/0.050179

Antilog(0.8784) = [Zn^2+]/0.050179

7.558 = [Zn^2+]/0.050179

[Zn^2+] = 7.558 * 0.050179

[Zn^2+] = 0.3793 M

NNADVOKAT [17]

Answer:

The question is not complete, the complete question should be "Lipids vesicles are formed containing pure water. If these vesicles are transferred to a solution that contains a rather high concentration of solutes, the solution outside the vesicle is said to be Hypertonic. True or False"

The answer is True

Explanation:

This is because it contains greater concentration of solutes on the outside of the cell than the increase.

In other words hypertonic solutions have more concentrate of solutions on the outside than the inside.
