What is the speed of a rocket in units of meter/ second if its travels at a speed of 1000 km/minutes?

Explanation:

The macrocyclic effect in coordination chemistry refers to the enhanced stability of metal complexes that have a macrocyclic ligand. A macrocyclic ligand is a ligand that forms a ring around the metal ion, forming a macrocyclic complex. This structure increases the enthalpy of the complex, making it more thermodynamically stable. In other words, the macrocyclic effect increases the stability of a metal complex by making the ligand more difficult to remove. This effect is especially important in biological systems, where macrocyclic ligands play a key role in many enzymatic reactions.

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

The equilibrium reaction will be,

In this reaction, and are base and acid and and are conjugate acid and conjugate base respectively.

Ammonia is a weak base because it accept proton from the water and gives fewer hydroxide ions.

Answer:

7.97 mol Ar

Explanation:

Use Avogadro's number to convert atoms to moles.  This number is the number of atoms in one mole.  There are 6.022 × 10²³ atoms in one mole.

Divide the number of atoms given by Avogadro's number.

(4.80 × 10²⁴)/(6.022 × 10²³) = 7.97 mol

There are 7.97 moles of argon.

Answer:

3.0 moles  (A P E X)

Explanation:

Final answer:

Buffer capacity denotes how much acid or base a buffer solution can integrate before alterations in pH becomes significant. It is crucial in maintaining physiological activities, particularly in blood pH regulation. The substance absorbing the ions is typically a weak acid/base and their conjugates.

Explanation:

Buffer capacity is the amount of acid or base a buffer solution can accommodate before the pH is significantly pushed outside of the buffer range. Solutions that contain sizable quantities of a weak conjugate acid-base pair are known as buffer solutions. These usually experience only slight changes in pH when small amounts of acid or base are added.

A large enough addition of these substances can exceed the buffer capacity, consuming most of the conjugate pair and leading to a drastic change in pH. In living organisms, a variety of buffering systems exist to maintain the pH of blood and other fluids within a strict range between pH 7.35 and 7.45, ensuring normal physiological functioning.

The substance that absorbs the ions is usually a weak acid, which absorbs hydroxyl ions, or a weak concentrate base, which absorbs hydrogen ions. The buffer capacity is greater in solutions that contain more of this weak acid/base and their conjugates.

Final answer:

Buffer capacity refers to the amount of acid or base that a buffer solution can absorb before experiencing a significant shift in pH, commonly by one pH unit.

Explanation:

Buffer capacity is the amount of acid or base a buffer can handle before pushing the pH outside of the buffer range. Essentially, it is a measure of a buffer's resistance to pH change upon the addition of an acid or base. Buffer capacity depends on the concentrations of the weak acid and its conjugate base present in the mixture. For instance, a solution with higher concentrations of acetic acid and sodium acetate will have a greater buffer capacity than a more dilute solution of the same components. The buffer's capacity is directly proportional to its ability to absorb strong acids or bases before there's a significant change in pH, typically defined as a shift by one pH unit.
