What mass of carbon dioxide is produced by the complete combustion of 48.0 g of hexane?

Answers

The mass of carbon dioxide produced by the complete combustion of 48.0g of hexane is 147.35g.

How to calculate mass?

The mass of a substance can be calculated by using the stoichiometry approach.

The balanced equation of the complete combustion of hexane is as follows:

2C6H14(g) + 19O2(g) → 12CO2(g) + 14H2O(g)

48g of hexane to moles is calculated as:

48g ÷ 86g/mol = 0.56 mol

2 moles of hexane produces 12 moles of CO2

0.56 mol of hexane will produce 0.56 × 12/2 = 3.35 mol

Next, we convert 3.35 moles of CO2 to mass as follows:

3.35 moles × 44g/mol = 147.35g

Therefore, the mass of carbon dioxide produced by the complete combustion of 48.0g of hexane is 147.35g.

Why does the oil in this soup gather into drops instead of dissolving evenly throughout the surface of the water

Answers

The water molecules cannot share intermolecular forces with the oil molecules

The water molecules must do hydrogen, but cannot when they touch the oil molecules

Oil drops do not spread across hot water because the surface tension of hot water is lower than that of oil. The water molecules cannot share intermolecular forces with the oil molecules. Thus the correct option is C.

Oil has a higher surface tension than hot soup. It prevents an oil drop from spreading over the heated soup. The surface tension of oil is lower than that of soup when the soup's temperature drops. As a result, the oil drop begins to spread across the soup.

The cohesive force between oil molecules is less than the adhesive force between oil and water molecules. As a result, water molecules and oil molecules do not mix.

Thus the correct option is C.

Answers

Answer:

Basic

Explanation:

The pH scale is measured from 0 to 14.

At the pH scale of 7, a solution is neutral.

Any solution above 7 is basic.

Any solution below 7 is acidic.

Because you have been given the hydronium concentration [H₃O⁺], you can find the pH of the solution using the following formula:

pH = -log[H₃O⁺]

pH = -log(6.0 x 10⁻¹²)

pH = 11.22

As you can see, the solution must be basic because the pH lies within the basic range.
