A buffer is made with sodium acetate and acetic acid
tamaranim1 [39]

Answer:

Because Water is not a buffer solution and the acetic acid/acetate solution is a buffer solution. An acidic buffer is a solution of a weak acid (acetic acid) and its conjugate base pair (sodium acetate) that prevents the pH of a solution from changing drastically through the action of each component with incoming acid or base.

Alinara [238K]

{answer}

An unsaturated solution is formed when 80. Grams of a salt is dissolved in 100. Grams of water at 40. °c. This salt could be.

Solubility is the maximum amount of soluble solid that can be dissolved in a 100-gram of water at a specific temperature. The solubility of a compound is directly proportional to the temperature which means that more solids can be dissolved at a higher temperature. Moreover, a solution which has a concentration below its solubility is an unsaturated solution. When both concentration and solubility are the same, then the solution is saturated. Lastly, when the concentration of a solution is higher than the solubility at a specific temperature, then the solution is called supersaturated.

An experiment is performed to measure the mass percent of caco3(s) in eggshells. Five different samples of caco3(s) of known mas
Arturiano [62]

The modification that produces the greatest increase in the rate of reaction is using more finely divided eggshells.

<h3>Rate of reaction</h3>

The term rate of reaction refers to how quickly reactants are consumed or how quickly products are formed. An exothermic reaction is one in which heat is given off.

The rate of reaction of solids is greatly influenced by surface area. If the eggshells are finely divided, the surface area is increased. Hence, the modification that produces the greatest increase in the rate of reaction is using more finely divided eggshells.
