Below is the solution:
n equation showing conservation of mass of reactants and products: 
<span>2H2O --> 2H2 & O2 </span>

<span>what is the mass of the oxygen gas produced, from 178.8 g H2O , (using molar masses: </span>
<span>178.8 g H2O @ (1mol O2)(@ 32.00 g/mol) / (2molH2O)(18.02g/mol) = </span>
<span>your answer (4 sigfigs): 158.8 g O2 </span>

<span>178.8 g H2O ---> 20.0 H2 & 158.8 O2</span>

Clear cutting large areas of trees at one time:
wariber [46]

All of the statements are true about the consequences of clear cutting large areas of trees at one time.

Explanation:

When a large area of trees is clear cut at once, or in a very short period of time, it brings significant changes to the area. The consequences are mostly environmental, and they affect all the living organisms in the area, including the humans. It is not only the living organisms that are affected though, but also the physical features and characteristics of the area. The climate too experiences changes very quickly, which are often negative changes.

  • The removing of the trees from an area exposes the land to direct sunlight, which results in higher temperatures.
  • The higher temperature of the land contributes to drying up of the land, thus gradually making the land semi-arid or arid.
  • Because the land will be drier and warmer, the air masses will be dry and warm, thus the rainfall will sharply decrease in the area.
  • Another major change will be that the rate of erosion will increase significantly, as the soil will not have its natural protection from the trees, so it will rapidly erode.
