<span>The question says,'Mathew was working with different concentrations of hydrochloric acid in the lab. Which of these would best describe the resulsts Mathew would see if he was using a conductivity apparatus in each of the different acid concentration. The correct answer is C. This is because, acids conduct electricity, the stronger the acid, the brighter the electricity that will be produced while the weaker the acid, the weaker the electricity that will be produced. Thus, higher concentration equals tronger electricity.</span>
<h3><u>Answer;</u></h3>
HCl and KCl
<h3><u>Explanation</u>;</h3>
- Strong electrolytes are strong bases and acids.
- HCl is a strong acid; it dissociates completely to form H+ and Cl- ions. Thus, it is a strong, rather than weak, electrolyte.
- CH3COOH is acetic acid, a weak acid. Only some of it will dissociate (to H+ and acetate ions), thus, it will only be a weak electrolyte.
- NH3 will react with water as a weak base: NH3 + H2O → NH4+ + OH-. It will thus also be a weak electrolyte.
- KCl is a soluble ionic compound, and as such, it will be a strong electrolyte.
The ball slowed down faster than the floor because the carpet has more friction than the floor. The carpet isn’t smooth but the floor is.
