It's asking about air currents and temperature and how they affect each other. Since the land is hotter than the water during the day, it will create different pressures that force air to move. <span>The wind will blow from the higher pressure over the water to lower pressure over the land </span>causing<span> the </span><span>sea breeze. The opposite happens at night, and that causes a land breeze.

How many moles of water are created if 3 moles of hydrogen react completely with excess oxygen?
Alenkinab [10]

Answer:

3.0 moles.

Explanation:

  • It is a stichiometry problem.
  • The chemical reaction of reacting hydrogen with oxygen to produce water is:

<em>H₂ + 1/2 O₂ → H₂O.</em>

  • It is clear that <em><u>1.0 mole of H₂</u></em> reacts with 0.5 mole of O₂ to produce <u><em>1.0 mole of  water</em></u>.
  • The ratio of the reacting hydrogen to the produced water is 1:1.

∴ The number of moles of water created from reacting 3.0 moles of hydrogen completely with excess oxygen = 3.0 moles.

Calculate the molarity of a solution that contains 3.11 mol of NaNO3 dissolved in 2.50 L. Enter your answer in the provided box.
rusak2 [61]

Answer:

Molarity of a solution that contains 3.11 mol of NaNO3 is 1,24 M

Explanation:

We understand molarity as the number of moles of solute that are contained in 1 L of solution, then if in a solution of 2.50 L we have 3.11 moles, it remains to calculate how many moles do we have in 1 liter.

2,50 L .......... 3,11 moles

1 L .................. x

X = ( 1 L x 3,11 moles) / 2,50 L = 1,24
