Answer:

158.5g Zn are produced

Explanation:

To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:

<em>Moles Al -Molar mass: 26.98g/mol</em>

43.6g Al* (1mol/26.98g) = 1.616 moles Al

<em>Moles Zn:</em>

1.616 moles Al * (3mol Zn / 2mol Al) =

2.424 moles Zn are produced

<em>Mass Zn -Molar mass: 65.38g/mol-</em>

2.424 moles Zn * (65.38g / mol) =

<h3>158.5g Zn are produced</h3>

Which part of the mantle is still solid but flows like a heavy liquid
topjm [15]

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>
