Which part of the mantle is still solid but flows like a heavy liquid

1 answer:

5 0

The Earth is composed of four different layers. Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top. Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy metals (nickel and iron).

<span>The crust is the layer that you live on, and it is the most widely studied and understood. The mantle is much hotter and has the ability to flow. The Outer and Inner Cores are hotter still with pressures so great that you would be squeezed into a ball smaller than a marble if you were able to go to the center of the Earth!!!!!!</span>

What is the acceleration of a 50kg object pushed with a force of 500 Newton’s

olasank [31]

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$

f is the force

m is the mass

From the question we have

$a = \frac{500}{50} = \frac{50}{5} = 10 \\$

We have the final answer as

If you have 10 grams of Lithium Oxide what will the volume be? Show your work

gogolik [260]

Answer:

Volume occupied by 10 grams of Lithium Oxide at STP is 7.52 L

Explanation:

STP (Standard Temperature and Pressure) : It is used while performing calculation on gases and provide standards of measurements while performing experiment.

According to IUPAC (International Union of Pure And applied Chemistry) , standard temperature is 273.15 K and Pressure is 100 kPa (0.9869 atm). At STP condition 1 mole of substance occupies 22.4 L volume .

Molar mass of Lithium Oxide = 29.8 g/mol

$Li_{2}O$ = 2(6.9) + 15.99 = 29.8

Mass of 1 mole $Li_{2}O$ = 29.8 g

1 mole $Li_{2}O$ occupies, Volume = 22.4 L

29.8 g $Li_{2}O$ occupies, V = 22.4 L

1 g $Li_{2}O$ occupies ,V = $\frac{22.4}{29.8}$

1 g $Li_{2}O$ occupies ,V = 0.7516 L

10 g tex]Li_{2}O[/tex] occupies ,V = $0.7516 \times10$ L

V = 7.52 L

So, volume occupied by Lithium Oxide At STP is 7.52 L
