The upper part of the mantle is Hard OR Soft

Chemistry
1 answer:
sladkih [1.3K]3 years ago
6 0

Answer: Hard

Explanation:

The upper part of the mantle is hard as it contains thick rock layers. The mantle's upper layer and the crust make up a brittle and rigid rock that's referred to as the Lithosphere.

The upper mantle starts below the Earth crust and then stops at the start of the lower mantle. We should note that the upper mantle results in the movement of the tectonic plates.

Three different sub-atomic particles are described below: Particle X: Uncharged Particle Y: Carries positive charge Particle Z:
bazaltina [42]

 The statement  which is true  about  the three sub atomic particles  is

X is  a neutron,Y is a protons and z is an electron

<u><em>Explanation</em></u>

  •  Atom  has three  sub  atomic    particles,that  is  neutrons,protons and electrons.
  • Neutrons have no electric  charge,protons  are positively  charged while electrons  are  negatively  charged.
  • Both  neutrons and proton are located in the nucleus while electrons  are  located outside the  nucleus.
  • since electrons   are located  outside the  nucleus  they  orbit  around the nucleus.

What happens to the concentration of NO₂(g) when the total pressure on the equilibrium reaction <img src="https://tex.z-dn.net/?
zepelin [54]

Answer:

1

Explanation:

To adequately account for what happens to volume when pressure is increased, we need to know exactly the type of volume change that occurred. Now as we can see, there is a volume change from 2 moles to 7 moles.

This shows an increase in volume. To favor the forward reaction, there should be a decrease in the volume which is unfortunately not the case here. Hence it’s the backward reaction that would be favored.

Since the formation of NO2 is in the forward reaction, then, we can see that its concentration will decrease
