Answer:

B. The material is cooler and denser.

Explanation:

The earth is made up of three layers, the crust, the mantle and the core. Each layer has different characteristics and temperatures, becoming warmer and less dense as it approaches the core.

Man has never reached the core of the earth, but the study of the internal structure of the planet is possible thanks to the studies of geophysicists, who are dedicated to the study of seismology. They observe the phenomena of seismic waves and rely on apparatus to define the characteristics of each layer.

  • Earth's crust: Most superficial layer, relatively thin structure and very rocky.
  • Mantle: Located below the crust, it has solid properties.
  • Core: Earth's warmest, least dense layer.

cestrela7 [59]
With the equation <span>A₂+2B₂→2AB₂ we know that one mole of A₂ is necessary to react with two moles of B₂ and with that, we obtain two moles of the product. ( you can see this by just seeing what numbers are before the letters)

Since it's needed more quantity of B than A,  B is the limited reagent.
