Answer: 2.8 moles

Explanation:

The balanced equation below shows that 1 mole of sodium oxide reacts with 1 mole of water to form 2 moles of sodium hydroxide respectively.

Na2O + H2O --> 2NaOH

1 mole of H2O = 2 moles of NaOH

Let Z moles of H2O = 5.6 mole of NaOH

To get the value of Z, cross multiply

5.6 moles x 1 mole= Z x 2 moles

5.6 = 2Z

Divide both sides by 2

5.6/2 = 2Z/2

2.8 = Z

Thus, 2.8moles of H2O are needed to produce 5.6 mol of NaOH

Which makes the phosphorus cycle different from the carbon cycles
azamat
<span>The phosphorus cycle is different compared to the water,carbon, and nitrogen cycle because it can not be found in the gas state. Phosphorus is only found in land, water, and sediment. The phosphorus cycle is a bio-geochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The other cycles is the process by which it is converted between its various chemical form. Phosphorus has small particles that only sometime go up into the atmosphere and contribute to acid rain but other than that phosphorus stays in and on land, sea, and sediment.(:
Good luck!</span>
