All atoms are of <u>neutral charge, with an equal amount of protons and electrons.</u>
Answer:
6.517.
Explanation:
- It is known that for pure water: [H₃O⁺] = [OH⁻], so water is neutral.
<em>Kw = [H₃O⁺][OH⁻] = 9.25 x 10⁻¹⁴.</em>
∵ [H₃O⁺] = [OH⁻].
∴ [H₃O⁺]² = 9.25 x 10⁻¹⁴.
∴ [H₃O⁺] = √(9.25 x 10⁻¹⁴) = 3.041 x 10⁻⁷ M.
∵ pH = - log[H₃O⁺]
<em>∴ pH</em> = - log(3.041 x 10⁻⁷) = <em>6.517.</em>
<u>Answer:</u> The Gibbs free energy of the reaction is -445 J/mol.
<u>Explanation:</u>
The chemical equation for the conversion follows:
The expression for of above equation is:
We are given:
[Glyceraldehyde-3-phosphate] = 0.00400 M
[Dihydroxyacetone phosphate] = 0.100 M
Putting values in above equation, we get:
Relation between standard Gibbs free energy and equilibrium constant follows:
where,
= Standard Gibbs free energy = 7.53 kJ/mol = 7530 J/mol (Conversion factor: 1kJ = 1000J)
R = Gas constant =
T = temperature = 298 K
Putting values in above equation, we get:
Hence, the Gibbs free energy of the reaction is -445 J/mol.
About <u>1 in 500,000,000</u> molecules in a glass of water are dissociated.
<h3>What is water?</h3>
Water can be defined as a liquid molecule or chemical compound that typically comprises two (2) main chemical elements in a ratio of two (2) atoms of hydrogen to one (1) atom of oxygen. This ultimately implies that, these two (2) chemical elements include the following:
Water is an amphoteric chemical compound (substance), which ultimately implies that it can accept a proton that is also acting as a base, while also donating a proton that acts as an acid as shown in the balance chemical reaction below:
2H₂O(l) ⇄ H₃O⁺(aq) + OH⁻(aq)
Based on scientific research and experiments, approximately one (1) water molecule in half a billion (500,000,000) dissociate into an OH⁻ ion, especially by losing a proton to another water molecule.
