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>
Answer:
the tigris and Euphrates river flow through Syria and Iraq into the Persian Gulf.
The area was once a forest.
The area was uplifted.
The area was buried in sediment.
The area was probably covered by water.
Petrification of a dead plant or animal organisms occurs when rock mineral displaces the organic elements in the structure of the biotic matter or these minerals seep in between the spaces and pores within the dead plant or organism and become part of the material.
Explanation:
Petrification occurs under high pressure. This is why this process occurs in the crust after layers of sediments create enough pressure on the dead organic matter buried in with the sediments. This phenomenon commonly begins on the ocean floor where dead marine life sinks to the bottom and is buried by sediments over many years.
Occasionally, tectonic plate forces uplift these petrified fossils from deep in the crust exposing them on the surface like in this case.
