If a mixture containing 0.50 moles of N2 and 1.8 moles of H2 is allowed to react according to the equation N2 3H2 2NH3 Group of
Lelechka [254]

Answer: hydrogen is the limiting reactant.

Explanation:

We have the equation \text{N}_{2}+3\text{H}_{2} \longrightarrow 2\text{NH}_{3}.

This means that for every mole of nitrogen consumed, 3 moles of hydrogen are consumed.

  • Considering the nitrogen, the reaction can occur 0.50 times.
  • Considering the hydrogen, the reaction can occur 1.8/3 = 0.6 times.

Therefore, <u>hydrogen</u> is the limiting reactant.

How does freezing affect the volume of water?
MrRissso [65]

Increases the volume of water

Explanation:

Freezing of water causes the volume of water to increase by a whooping 4%. This is why the density of water is slightly different that of ice.

When ice freezes it expands and takes up more volume of space for the same mass given.

This is why bottles break when water in them is frozen.

This increase in volume is why ice floats on water. It makes it less dense.

Why can you never see the far side of the mood from earth?
Yuliya22 [10]

Answer: -

C) because the moon rotates once on its axis in the same time that it takes to revolve around the earth

Explanation: -

The moon rotates about it's axis one full time at about the same time as it takes to rotate around the earth.

This leads to only one side of the moon always appearing to Earth, called the near side.

One side of the moon is always not seen from the earth. It is called the far side of the moon.

Thus we can never see the far side of the moon because the moon rotates once on its axis in the same time that it takes to revolve around the earth
