Answer:

Disagree.

Explanation:

Nothing would remain. Everything on Earth is made up of atoms. The chair consists of only atoms. So, if you remove all of the atoms, nothing would be left! Hope this helps.

State and explain the relative change in the pH and in the buffer-component concentration ratio, [NaA]/[HA], for each of the fol
melisa1 [442]

When pure HA is added to the buffer, the buffer component ratio and the pH decrease.

<h3>State and explain the relative change in the pH and in the buffer-component concentration ratio, [NaA]/[HA] for the dissolve of pure HA in the buffer.</h3>

When pure HA is added to the buffer, the buffer component ratio and the pH decrease. The added HA increases the concentrations of NA and HA. However, there is a greater relative increase in the concentration of HA. Hence, the ratio of [NaA]/[HA] decreases, causing the solution to become more acidic.

The capacity of a buffer to withstand pH change is measured. The concentration of the buffer's components namely, the acid and its conjugate base determine this ability. Greater buffer capacity is associated with higher buffer concentration.

5. A 180 mL disinfectant solution contains 85 mL of isopropyl alcohol. Determine the V/V
lyudmila [28]

The % V/V concentration of a 180-mL disinfectant solution containing 85 mL of isopropyl alcohol is 47 % V/V.

<h3>What is the % V/V concentration?</h3>

It refers to the milliliters of solute for every 100 milliliters of solution.

We have 180 mL of a disinfectant solution that contains 85 mL of isopropyl alcohol (solute).

The % V/V concentration of this solution is:

% V/V = (mL solute/mL solution) × 100% =

% V/V = (85 mL/180 mL) × 100% = 47% V/V
