Answer:
Kc = 2.145 × 10⁻⁸¹
Explanation:
Let's consider the following reaction:
O₂(g) ⇄ 2O(g)
The standard Gibbs free energy for the reaction (ΔG°) can be calculated using the following expression:
ΔG° = Σnp. ΔG°f(p) - Σnp. ΔG°f(p)
where,
ni are the moles of products and reactants
ΔG°f(p) are the standard Gibbs free energy of formation of products and reactants
In this case,
ΔG° = 2 × ΔG°f(O) - 1 × ΔG°f(O₂)
ΔG° = 2 × 230.1 kJ/mol - 1 × 0 kJ/mol
ΔG° = 460.2 kJ/mol
With this information, we can calculate the equilibrium constant (Kc) using the following expression:
Answer:
2.843 M
Explanation:
Molarity = moles / volume
<u>Milliliters to liters:</u>
500 mL <u>= .500 L</u>
<u>Grams to moles:</u>
MgO molar mass = 16.00 + 24.31 = 40.31 g/mol
57.3 g x 1 mol / 40.31 g = <u>1.421 mol</u>
<u>Molarity:</u>
1.421 mol / .500 L = 2.843 M
A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture, or material type.
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
Aldol condensation is an easy way of making carbon-carbon bond.
In the field of chemistry, we can describe aldol condensation as a type of bond that occurs due to electrophilic substitution at the alpha carbons of the enol.
Aldol condensation is known to be the easiest way for one carbon to form bonds with another carbon.
Such an aldol reaction that takes place between carbonyl compunds instead of aldehydes or enols is referred to as crossed aldol condensation.
Aldol reactions are known to be an important part of synthesizing organic compounds as carbon-carbon bonds are formed due to it.
