3. What is the greatest amount of H2O that can be made with 3.8 moles of H and 5 moles of
Pachacha [2.7K]

Answer:  Hello!

first i believe we need a balanced equation to start...

i got 2H2 + 1O2 = 2H2O

This tells us that we need 2 moles of H2 for every 1 mole of O2 Since we only have 1 mole of H2 compared to the 5 moles of O2 hydrogen is the limiting reagent. For illustration, divide the balanced equation by 2 in order to get 1 mole of H2 If we start with 1.0 moles of H2 we'll produce 1.0 mole of H2O

Hey,

There are thousands of way to separate mixtures. Each way is specific to the type of mixture. If the mixture is homogeneous processes like distillation can be employed. For heterogeneous mixture filtration can be used to separate particles of different sizes.

  • Phytoplankton are  plants and they are the major producers in bodies of water.
  • The require the process of photosynthesis to manufacture their food.
  • During photosynthesis, phytoplankton takes in carbon dioxide and water and uses light to produce food in the process.
  • This life activity greatly relies on light.
  • The upper part of the ocean usually from 0-200m depth is the photic zone.
  • Deeper water is aphotic and receives little to no sunlight.
  • The photic zone is the zone where light reaches in water.
  • There is abundance of light in the photic zone.
