IgorC [24]4 years ago
6 0

 The mole fraction of helium in a vessel that contain threes gases  with a partial pressure of : 100 torr oxygen, 300 torr  helium and 200 torr neon  is  0.50


          <u><em>calculation</em></u>

  •    mole  fraction  =    partial pressure for helium  divided by total pressure
  • Total pressure=partial pressure of oxygen + partial  pressure for Helium +partial pressure for  neon

   =  100+300+200=600

  • mole fraction is therefore= 300/600=  0.50

The reaction below shows how the potential energy changes during a
pochemuha

The change in enthalpy shows on the graph is the red arrow shows that enthalpy is positive, indicating an endothermic reaction.

<h3>What is potential energy?</h3>

Energy is the basic thing to do any reaction or any process. There are many kinds of energy are present that are use indifferent processes.

Potential energy is the energy that is saved to do a work, or the energy that is present before a work occurred.

The graph is attaches below.

Thus, the correct option is A. The red arrow shows that enthalpy is positive, indicating an endothermic reaction.

List and describe the two major types of plastics.​
stiv31 [10]

Answer:

Thermoplastics and thermosets

Explanation:

The two key categories of plastic are thermoplastics and thermosetting plastics (thermosets). Thermoplastic products have the ability to be continually softened, melted and reshaped/recycled, for instance in injection molding or extrusion resins. However, thermoset products do not have this property.
