Answer:

2.5 moles of H2

Explanation:

First, let us write a balanced equation for the reaction of Hydrogen to produce water. This is shown below:

2H2 + O2 —> 2H2O

From the equation above,

2 moles of H2 produced 2 moles of H2O.

Therefore, 2.5 moles of H2 will produce 2.5 moles of H2O

Explain how intermolecular attractions between molecules influence the bulk of properties of a material

irina1246 [14]

Answer:

Intermolecular forces determine bulk properties, such as the melting points of solids and the boiling points of liquids. Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.
