What is the idea of continental Drift?

Continental drifts was a theory that explained in how continent shift position on the earth surface.

The theory was presented in 1912 by Alfred Wegener, who was a geophysicist and meteorologists. The theory also explained the reason why plant and animal fossils that look similar are found all over the continents.

<h2>Further Explanation</h2>

Wegener had the thought that all the different continents were at a point joined together before it breaks up and moves to their present position.  

Wegener published a book in 1915 called "The Origin of Continents and Oceans. In this book, he further explained the theory of continental drifts but the theory was widely criticized by geologists because to them, wegener did not have a good model to properly explain how the continent drifted apart.

From Wegener explanation, there were certain things he laid emphasis on, which were very accurate, like the observation about fossils and rock. Wegener thought that the Continent might have plowed through the ocean crust just like icebreakers smashing through ice.

Although, Weneger continental drift theory was discarded but there are certain facts that he established. The theory brought the idea of moving continents to geoscience and after many decades, scientists confirms most of the things the theory covered. For example, the idea that the past existence of supercontinent joined all the landmass of the world as one.

A 500.0 g block of dry ice (solid CO2, molar mass = 44.0 g) vaporizes at room temperature. Calculate the volume of gas produced
Damm [24]

Considering the ideal gas law, the volume of gas produced at 25.0 °C and 1.50 atm is 184.899 L.

<h3>Definition of ideal gas</h3>

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

<h3>Ideal gas law</h3>

An ideal gas is characterized by absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of gases:

P×V = n×R×T

<h3>Volume of gas</h3>

In this case, you know:

  • P= 1.50 atm
  • V= ?
  • n= 500 g×\frac{1 mole}{44 g}= 11.36 moles, being 44 \frac{g}{mole} the molar mass of CO₂
  • R= 0.082 \frac{atmL}{molK}
  • T= 25 C= 298 K (being 0 C=273 K)

Replacing in the ideal gas law:

1.50 atm×V = 11.36 moles×0.082\frac{atmL}{molK} × 298 K

Solving:

V= (11.36 moles×0.082\frac{atmL}{molK} × 298 K) ÷ 1.50 atm

<u><em>V= 184.899 L</em></u>

Finally, the volume of gas produced at 25.0 °C and 1.50 atm is 184.899 L.

If an atom has 8 protons. How many electrons does it have? What is the atoms charge?
Juli2301 [7.4K]
The amount if protons is the same as the amount of electrons, so it would be 8. The charge is -2. Look at oxygen in the periodic table.

A car travels at 35.0 mi/hr. How far has it gone in 2455 seconds?
Vika [28.1K]

Answer:

<h3>The answer is 23.8 miles</h3>

Explanation:

The distance covered by an object given it's velocity and time taken can be found by using the formula

<h3>distance = velocity × time</h3>

From the question

velocity = 35.0 mi/hr

time = 2455 s = 0.68 hr

We have

distance = 35 × 0.68

We have the final answer as

<h3>23.8 miles</h3>

Hope this helps you
