Answer:

answer A

Explanation:

A) the quantity of usable energy declines with each transformation → True . Since the entropy increases , the amount of energy that can not be converted to useful energy increases and since the total amount of energy is conserved, the quantity of useful energy decreases.

B) energy can be neither created nor destroyed → False in the context of entropy , since the energy is conserved regardless of the changes in entropy (First law → conservation of energy vs second law → increase of entropy)

C)  life should be impossible → False . Since the second law states that the entropy of the <u>universe </u>increases with time . Then the system (life) can experience a decrease in entropy  at the expense of a larger increase in entropy of the surroundings ( so the net increase is positive)

D) it is not possible to observe an increase in molecular organisation → False . Same as C. A system  can experience a decrease in entropy at the expense of a larger increase in entropy of the surroundings ( so the net increase is positive)

Blank 1: polar
The difference in electronegativity between N and H causes electrons to preferentially orbit N, making the bond polar.

Blank 2: trigonal pyramidal
There are four “things” attached to N - 3 H’s and 1 lone pair of electrons. The four things together are arranged into a tetrahedral formation. However, the lone pairs don’t actually contribute to the shape of the molecule per se; it’s only the actual atoms that do. The lone pair creates a bit of repulsion that pushes the 3 H’s down, creating a trigonal pyramidal shape (as opposed to a trigonal planar one).

Blank 3: polar
The molecule as a whole is also polar because the “things” around it, though arranged in a tetrahedral pattern, are not all the same. The side of the molecule with the lone pair is slightly negative, while the side with the 3 H’s is slightly positive due to the differences in electronegativity described above.

Where would you have the least weight?​
Vikki [24]

In a place with no gravity

Explanation:

Weight is a force exerted by a body in the presence of gravity.

        Weight = mass x gravity

Without gravity, there is no force of weight. The more the gravity, the more the weight of a body.

A body will experience weightlessness in a place without no gravity.

Therefore, one will experience the least weight in a place without the pull of gravity.

The pressure on 30 milliliters of an ideal gas increases from
Nana76 [90]

V1 = 30 mL

P1 = 760 torr

P2 = 1520 torr

V2 = ?

applying Boyle's Law

P1*V1 = P2*V2

760 torr * 30 mL = 1520 torr * V2

V2 = 760 torr * 30 mL / 1520 torr

( C ) is correct
