Find the number of moles of water that can be formed if you have 226 mol of hydrogen gas and 108 mol of oxygen gas.

Anit [1.1K]

Answer is: there are 216 moles od water.
Chemical reaction: 2H₂ + O₂ → 2H₂O.
n(H₂) = 226 mol.
n(O₂) = 108 mol; limiting reactant.
From chemical reaction: n(O₂) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(O₂).
n(H₂O) = 2 · 108 mol.
n(H₂O) = 216 mol.
n - amount of substance.

An unknown substance is heated from 10 °C to 25 °C. The table below shows the state of the substance at different temperatures.

bezimeni [28]

Answer:

Its melting point is 17 °C.

Explanation:

The melting point of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium.

<em>So, the melting point is 17 °C.</em>

And this is shown in the figure attached.
