Hexane burns in air to form carbon dioxide and water. The oxygen is store at 40.0 Celsius and at a pressure of 106.6kPa. How many moles of oxygen will react with 500. Grams of hexane

55.233 moles of oxygen will react with 500 g of hexane.

Explanation:

To calculate the number of moles, we use the equation:

Given mass of hexane = 500g

Molar mass of hexane = 86 g/mol

Putting values in above equation, we get:

The chemical equation for the reaction of burning of hexane in air follows:

By stoichiometry of the reaction:

2 moles of hexane reacts with 19 moles of oxygen

So, 5.814 moles of hexane will react with = of oxygen

Hence, 55.233 moles of oxygen will react with 500 g of hexane.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
