This <u>heterogeneous </u>mixture is a suspension of oil and vinegar

A mixture is a physical combination of two or more substances and each of these substances preserves its identity and form in the mixture.

A homogeneous mixture is a mixture in which is one substance thoroughly dissolves in the other and its composition is uniform throughout the solution. e.g salt and water.

A heterogeneous mixture is one in the two substances form two layers and their composition varies throughout the mixture.

From the given information, the mixture of oil and vinegar is an example of a heterogeneous mixture.

How many electrons can be described by the quantum numbers n = 3, l = 3, ml = 1?
Oksana_A [137]

There are a total of four quantum numbers that govern the electrons. These are the principal quantum number (n), the angular quantum number (l), the magnetic quantum number (ml) and lastly the spin quantum number (ms). Each electron has a unit set of the four quantum numbers.

Since the first 3 quantum numbers is already specified, so the remaining to be filled is the ms quantum number which can only have values of +1/2 and -1/2. So we have 2 electrons.

 

Answer:

<span>2 electrons</span>

A scientist measures the standard enthalpy change for the following reaction to be 67.9 kJ:
hodyreva [135]

Answer:

-252.5 kJ/mol = ΔH H2O(g)

Explanation:

ΔH Fe2O3 = -825.5kJ/mol

ΔH H2 = 0kJ/mol

ΔH Fe = 0kJ/mol

Based on Hess's law, ΔH of a reaction is the sum of ΔH of products - ΔH of reactants. For the reaction:

Fe2O3(s) + 3 H2(g) →2Fe(s) + 3 H2O(g)

ΔHr = 67.9kJ/mol = 3*ΔH H2O + 2*ΔHFe - (ΔH Fe2O3 + 3*Δ H2)

67.9kJ/mol = 3*ΔH H2O + 2*0kJ/mol - (ΔH -825.5kJ/mol + 3*Δ H2)

67.9 = 3*ΔH H2O(g) + 825.5kJ/mol

-757.6kJ/mol = 3*ΔH H2O(g)

<h3>-252.5 kJ/mol = ΔH H2O(g)</h3>
