7 0

Answer:

Acid rain this results when gaseous emissions of sulphur oxide, nitrogen oxide etc come in contact with water vapour and sunlight and are chemically converted to strong acidic compounds such as sulphuric acid, nitric acid etc, and are carried to the earth by rain drops, snow flakes, flog or dew.

The heat of vaporization for water is 40. 7 kJ/mol. How much heat energy must 150. 0 g of water absorb to boil away completely?
netineya [11]

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

The heat of vaporization has been the amount of heat required to vaporize 1 gram of liquid.

The heat required for the vaporization has been given as:

Q=m\Delta H_{vap}

<h3 /><h3>Computation for the Heat of vaporization</h3>

The heat of vaporization of water has been given as, \Delta H_{vap}=40.7\;\rm kJ/mol

The mass of water sample has been, m=150\;\rm g

Substituting the values for the heat energy absorbed, <em>Q:</em>

<em />

<em />Q=150\;\times\;40.7\;\rm kJ\\&#10;\textit Q=6,105\;kJ

The heat absorbed by the water sample for vaporization has been 6,105 kJ. Thus, option D is correct.

The process of ____ occurs when magma, lava, or a solute in a solution becomes a solid and the internal components will arrange
satela [25.4K]

Answer:

D. Crystallization

Explanation:

Let's clarify the irrelevant terms first.

  1. unification: This term has nothing to do with chemistry at all
  2. lithification: When the problem mentions magma and lava, you might think that this term is related to the process here. However, 'lithification' <em>do </em>have a precise meaning in geology. It refers to the process where sediments collapses into one single rock under pressure, which has nothing to do with the process mentioned here.

Now, for 2 terms that might confuse you: 'solidification' and 'crystallization' these also has precise scientific definition

Solidification is defined the process where substances in <em>liquid</em> phase changes its phase to <em>solid</em>. On first glance, this answer might seems correct, and yes, it is correct for this question. But not the <em>most</em> correct.

The keyword here is  

 'the internal components will arrange its self in an  organized pattern.'

Crystallization is a special case of Solidification where the atoms or molecules of liquid solidify by spontaneously arrange themselves in periodic, ordered, and organized pattern. It might or might not happen during solidification depending on cooling rate, viscosity of liquid, and other factors.

So, Crystallization is the most correct answer here.

A system contains bonds between particles. Which choice describes the microscopic structures of the energy in this system? There
borishaifa [10]

Answer:

The correct answer is: <em>There must be potential energy in the bonds due to its particles position.</em>

Explanation:

Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact,  chemical energy is considered a form of potential energy (stored in chemical bonds).
