Answer:

The pH of the buffer is 4.77

Explanation:

Using Henderson-Hasselbalch equation we can solve the pH of the buffer:

pH = pKa + log [A⁻] / [HA]

<em>Where pH is the pH of the buffer</em>

<em>pKa is -log Ka = 5.056</em>

<em>[A⁻] = [NaA] = 0.2M</em>

<em>[HA] = 0.39M</em>

<em />

Replacing:

pH = 5.056+ log [0.2] / [0.39]

pH = 4.77

<h3>The pH of the buffer is 4.77</h3>

Is a substance that a filter can seperate into two parts a mixture or a pure substance?
jok3333 [9.3K]
Mixture. Mixtures can be separated into their component parts, while substances are chemically bonded atoms that can't be separated by physical means.

Discuss whether two products are required for a chemical reaction. (NEED HELP ASAP)
Alex787 [66]

Answer:

Yes.

Explanation:

"These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products."

There is a beginning product, and a reactant is needed in order for something to happen.

For example, according to Newton, something cannot happen until an exterior force comes and stops/pushes it.

Sorry if this is incorrect, I am just 4th grade :(
