Which processes of the water cycle involve the movement of water in the liquid state?
dangina [55]

Answer:

Surface runoff and condensation

Explanation:

Let's define each of the given processes in order to understand them better:

  • evaporation is a process in which liquid phase transforms into a gas phase;
  • precipitation is a process in which we produce a solid phase, usually this is the case when we precipitate a salt out of a solution, analogy of precipitation for water would be transformation from a liquid to a solid phase, such as freezing;
  • surface runoff is a process in which water flows over the surface of a land without any change in its phase;
  • condensation is a process in which a gas transforms into a liquid.

All in all, notice that surface runoff keeps water in its liquid state, while all the other three options consider phase change. The only phase change of interest is condensation: we produce liquid water from water vapor and then we can analyze its movement in the liquid state.

What is the volume of 0.2 moles of neon gas at STP?
eduard

Standard Molar Volume is the volume occupied by one mole of any gas at STP. Remember that "STP" is Standard Temperature and Pressure. Standard temperature is 0 &176:C or 273 K. Standard pressure is 1 atmosphere or 760 mm Hg (also called "torr"). 1 mole of any gas at STP occupies 22.4 liters of volume.

When are the products of an equilibrium reaction favored? When the reaction is endothermic. When the equilibrium constant is lar
PtichkaEL [24]
Product are favored at ...


example 2A + 3B = 5C + D    if reaction is exothermic ....delta H = NEGATIVE)


A decrease  in temperature favors the forward reaction (more product formed)
as heat is considered as a product

For the exam I have given: A decrease in pressure (volume increases as pressure decreases) .... there are more number of moles on the product side (6 in all) .....so according to LCP decreasing pressure will revert back to increase pressure and to do that equilibrium position shifts to the right (product)

decreasing concentration of product will cause a disturbance in equilibrium position....and reaction will restore its equilibrium by shifting to the  right


(I believe its like this)
