Lithium seems to have dramatic effects on the nervous system, yet our bodies seemingly never evolved to use lithium endogenously

, rather focusing on sodium, potassium, and calcium. what is a plausible explanation for this?

Given its small size and high polarizing power, lithium is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.

<h3>What is lithium?</h3>

Lithium is a metal and a member of group 1 in the periodic table. It is a very small ion hence it has a different chemistry from the rest of the members of the group.

Lithium is not part of any of the biomolecules because given its small size and high polarizing power, it is only involved in covalent rather than ionic bonds in the body as does sodium, potassium, and calcium.

Vitek1552 [10]

Answer:

Equilibrium concentrations of Ammonia and Hhydrogen sulphide are 0.2M respectively

Explanation:

Equilibrium constant is represented by the symbol k, it may be in terms of pressure (Kp) or concentration (Kc). Equilibrium constant is the ratio of the equilibrium concentration of the products of a reaction to the equilibrium concentration of the reactants with each concentration raised to the power of its corresponding coefficients.

There are rules guiding the writing of equilibrium constant, one of them is that the equilibrium constant or concentration for pure liquid or solid is 1

1. Perform calculations to determine the amount of 6.00x10-5 M stock solution needed to prepare 20.00 mL of 2.00x10-5 M dye solu
zhannawk [14.2K]

Answer:

1a. 6.70 ml of stock dye solution is required

1b. 10.0 ml of stock dye solution is required

1c. 4.00 ml of stock dye solution is required

Explanation:

1a. Using m₁v₁ = m₂v

6.00 * 10⁻⁵ * v₁ = 20.0 * 2.00 * 10⁻⁵

v₁ = 4 * 10⁻⁴/6.00 * 10⁻⁵

v₁ = 6.70 mL of stock solution

Therefore, 6.70 ml of stock dye solution is required

b. Using m₁v₁ = m₂v

2.00 * 10⁻⁵ * v₁ = 20.0 * 1.00 * 10⁻⁵

v₁ = 2 * 10⁻⁴/2.00 * 10⁻⁵

v₁ = 10.0 mL of stock solution

Therefore, 10.0 ml of stock dye solution is required

c. Using m₁v₁ = m₂v

1.00 * 10⁻⁵ * v₁ = 20.0 * 2.00 * 10⁻⁶

v₁ = 4 * 10⁻⁵/1.00 * 10⁻⁵

v₁ = 4.00 mL of stock solution

Therefore, 4.00 ml of stock dye solution is required

The procedure is then followed as in steps 2 to 4.

Dmitrij [34]

Answer:

Acid-Catalyzed Ester Hydrolysis

Explanation:

Fischer Esterification is a reversible reaction and the Le Châteliers principle can be used for the reaction to be completed. For the reverse reaction of Fischer Esterification, using the hydrolysis of ethyl ethanoate, the steps involved are:

1) An hydrogen ion is added to the ester and one of the lone pairs on the oxygen double-bonded to the carbon atom takes the hydrogen ion.

2) The lone pairs on the oxygen of a water molecule takes the positive charge on the carbon atom.

3) The hydrogen ion is transferred from one oxygen atom to another.

4) Then an ethanol molecule is released (one of the products).

5) Reaction with a water molecule releases hydrogen from the oxygen and the other product (ethanoic acid) is formed.
