there callled tidal bulgdes and they are on both poles

Verdich [7]2 years ago

The two bulges are called tidal bulges. There are two tidal bulges on opposite sides of Earth. One is beneath the moon and the other is opposite to that. The one below the moon is thought of as gravitational. It is produced by gravitational attraction between water molecules in the ocean and the moon.

<span>Now, about the other bulge. Think about inertia and what happens when masses rotate around a single point. Imagine yourself swinging a bucket of any liquid with your arm in a circular gesture. Even as the bucket goes over your head, the water is still held in the bucket and doesn't splash all over you. This rotation creates a centrifugal force. A similar event occurs during the lunar month as the earth/moon system rotates. The moon orbits the earth, but the rotation axis for this orbit isn't earth's center. Both the moon and Earth move during the roughly 28-day period it takes for the orbit, and because of this, water in the ocean is thrown to the outside, the same as the water in your bucket. The tidal bulge on the opposite side of Earth from the moon is produced by this inertial effect, referred to as centrifugal force.</span>

covalent bond would be formed in which pair of elements? Carbon and oxygen, any two noble gasses, sodium and chlorine , between

SOVA2 [1]

Answer:

Carbon and Oxygen, Argon and Helium.

Explanation:

noble gases have full outer shells of electrons, and so cannot share other atoms' electrons to form bonds. sodium and chlorine form an ionic bond.

4. When is distillation used?

Arlecino [84]

Answer:

Uses of Distillation

Distillation is used for many commercial processes, such as the production of gasoline, distilled water, xylene, alcohol, paraffin, kerosene, and many other liquids. Gas may be liquefied and separate. For example: nitrogen, oxygen, and argon are distilled from air.

For the reaction C (s) + H2O (g) --> CO (g) + H2 (g) ΔH = 131.3 kJ/mol and ΔS = 133.6 J/K-mol at 298K. At temperatures greate

TiliK225 [7]

Answer:

The reaction is spontaneous when T> 0.98 Kelvin OR T> -272.17°C

Explanation:

Step 1: Data given

ΔH = 131.3 kJ/mol = 131300 J/mol

ΔS = 133.6 J/K*mol

T = 298K

Step 2: The balanced equation

C (s) + H2O (g) --> CO (g) + H2 (g)

Step 3: ΔG

For a reaction to be spontaneous, ΔG should be <0

When ΔG > 0 the reaction is spontaneous in the reverse direction.

ΔG = ΔH - TΔS

Since ΔG<0

ΔH - TΔS <0

Step 4: Calculate T where the reaction is spontaneous

ΔH - TΔS <0

131300 J/mol - T*133.6 J/K*mol <0

- T*133.6 J/K*mol < -131300 J/mol

-T <-131300 /133.6

-T< -982.8 Kelvin

T> 982.8 Kelvin OR T> 709.6°C

The reaction is spontaneous when T> 982.8 Kelvin OR T> 709.6°C

At 298 K this reaction C (s) + H2O (g) --> CO (g) + H2 (g) is <u>not spontaneous</u>

Relate metallic bonds to the properties of metals.

loris [4]

Metallic bonds can conduct electricity. It depends on what type of metal you use because everything has a different chemical make up and different bond. Metallic bonds make it easy for some metals to be ductile meaning that they can be stretched into thin wires and they can also be malleable which means they can be pound into thin sheets. Also certain atoms will react with water to make rust.
