Avogadro constant
N = 8.27 * 6.022×10^23
N = 4.98 × 10^ 24particles.
In 8.27 moles of SiH, there are
4.98 × 10^24particles.
Answer:
H₃PO₄/H₂PO₄⁻ and HCO₃⁻/CO₃²⁻
Explanation:
An acid is a proton donor; a base is a proton acceptor.
Thus, H₃PO₄ is the acid, because it donates a proton to the carbonate ion.
CO₃²⁻ is the base, because it accepts a proton from the phosphoric acid.
The conjugate base is what's left after the acid has given up its proton.
The conjugate acid is what's formed when the base has accepted a proton.
H₃PO₄/H₂PO₄⁻ make one conjugate acid/base pair, and HCO₃⁻/CO₃²⁻ are the other conjugate acid/base pair.
H₃PO₄ + CO₃²⁻ ⇌ H₂PO₄⁻ + HCO₃⁻

The S-Enantiomer of Valine is attached below.
Assigning S-Configuration:
In Valine there is only one <em>chiral carbon</em> (carbon to which all bonded atoms or group of atoms attached have different masses). This carbon also known as <em>alpha carbon</em> has a tetrahedral geometry. For S-configuration, according to<em> Cahn Ingold Prelog Rules</em> the -NH₂ group is assigned with priority order of 1, The carbon of carboxylic acid is assigned the number two and the tertiary carbon is assigned with number three. These three groups are made in such a way that moving from number 1 to number 3 makes a S sign or anticlockwise rotation while keeping the hydrogen atom behind the plane.
Answer:
Explanation:
AlCl₃ forms a dimer in vapor state in order to compensate for the insufficient number of electrons that will make it attain stability in its structure.
Dimerization is a situation in which a molecule of a compound is derived from two identical monomers.
- Dimerization yields very weak/strong intermolecular interaction producing some chemical bonds.
- In the monomeric state, AlCl₃ does not have a complete octet.
- When in the vapor state, they attach to one another to compensate for this deficiency to attain stability.
