Answer:
41.43 mL
Explanation:
First we <u>calculate the mass of NaOH in the original solution</u>:
- 25.0 % m/v means that in 100 mL of solution, there are 25 grams of NaOH.
- This means that in 5.80 mL, we would have (5.80 * 25/100) <u>1.45 grams of NaOH.</u>
Then we <u>calculate the volume of the diluted solution</u>, using the grams of NaOH (that remain the same throughout the dilution process):
- 1.45 g NaOH * = 41.43 mL
Answer: -
Rutherford and Soddy's research involved:
3)The theory that uranium successively disintegrated to lead
Radioactivity involves conversion of one atom of an element into another by particle decay or radiation. They stated the disintegration theory of radioactivity, also discovering a large number of radioactive elements.
They both got Nobel prizes as well.

<h3>What is pH?</h3>
The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.
The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.
⇒pH = -log()
Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.
