Which theory describes the motion of and force driving earth’s plates?
swat32

The theory that describes the motion and force driving earth's plates is Plate tectonics

Explanation:

Plate tectonics states that the outer shell of the Earth is divided into plates that glide and move over the mantle which is the surface of the earth.

The mantle is the rocky inner layer above the core of the Earth.

Plate tectonics helped the geologists to explain how continents could move around the planet.

There are 9 major plate tectonics , namely North American, Pacific, Eurasian, Australian, African, Indo - Australian,Indian South American and Antarctic. These plates have been named after the land form found on them.

1) For example, sodium oxide (Na₂O).

One one molecule of sodium oxide has one sodium atome (Na) and two oxygen atoms (O).

The subscript after element shows the number of elements in a molecule.

2) Yes, it possible for two different compounds to be made from the exact same two elements.

This are isomers, same molecular formula, but different arrangements of atoms.

For example, n-butane (C₄H₁₀) and 2-methylpropane (C₄H₁₀).

3) There are large number of compounds in this world, around 40 millions.

Answer:

I'll do the first one for you. The reason why I'm not going to do the rest is because this is pretty simple stuff. I'll explain how I got the answer, please read it ^^ the rest of the problems should be a breeze.

1. 5.454285714285714 liters, or approx. 5.45 liters

Explanation:

P1V2 = P2V2

P1 refers to the original pressure. V1 refers to the original volume, or the amount of space the gas takes up.

P2 and V2 refer to the final pressure or volume, accordingly.

You insert the values into the equation, like so:

(8.3)(46) = (70)(x)

Now, multiply.

381.8 = 70x

Use inverse operations to find the value of x. Divide 381.8 by 70 to isolate x.

381.8/70 = x

5.454285714285714 = x

The volume of the gas when the pressure is increased to 70.0 mm Hg is approximately 5.45 liters. Don't forget about the units at the end, when you write your final answer.

Important! When pressure <em>increases</em>, volume <em>decreases, </em>and vice versa. Volume and pressure for gases are <em>inversely proportional. </em>So even though the pressure increased, that doesn't mean the volume increases, too.

<em>You can check your answers easily!</em>

Just multiply your final answer by its corresponding pressure or volume and compare it to the other. I hope that made sense. Like so:

5.454285714285714 x 70 = 381.8

8.3 x 46 = 381.8

That makes P1V2 DOES equal P2V2, and your answer is correct.

I hope this helped in time for you to submit it before the deadline! Good luck.

<em>Tips! </em>

For #2: I'm pretty sure the mentioning of the temperature (25.0 °C) doesn't matter. You can ignore it, it won't affect your calculations.

For #4: the standard pressure in mm Hg (millimeters of mercury) is 760 mm Hg. That's your P2.
