Answer:

-6300J

Explanation:

The quantity of heat required to raise the temperature of a substance per unit of mass could be written as:

Q = -m×C×ΔT

<em>Where Q is heat, m is mass of substance, C is specific capacity and ΔT is change in temperature</em>.

Replacing:

Q = -175g × 2.4J/gK × (38.6°C-23.7°C)

Q = -6258J ≡ <em>-6300J</em>

3. 200 ml of 0.2 M HCl is neutralized with 0.1 M
algol [13]

Answer:

  • <u><em>a. 0.1 M</em></u>

Explanation:

By definition, <em>half neutralization</em> is the point at which half of the acid has been neutralized.

The neutralization reaction that you are studying is the acid-base reaction:

  • HCl (aq) + NaOH (aq) → NaCl(aq) + H₂O (aq)

Then, since the starting molarity of the acid (HCl) is 0.2 M, you just need to find half of that concentration:

  • Half molarity = M / 2 = 0.2 M / 2 = 0.1 M

So, the answer is the first choice: a. 0.1 M.
