What is the melting point of a substance?
Alona [7]

Answer:

The answer is C) The temperature at which the solid-state turns into liquid

Explanation:

The melting point of a substance is the temperature at which it shifts state from solid to liquid. At the melting point, the solid and liquid levels exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change. This occurs when the internal energy of the solid increases, commonly by the application of heat or pressure, which increases the substance's temperature to the melting point.

Question 18 (Essay Worth 8 points)
DENIUS [597]

Yes, the law of conservation of mass holds.

Explanation:

In every chemical reaction, mass is always conserved. This implies that in chemical reaction, the process proceeds maintaining the same set of atom in the same proportion without new ones forming.

  • From the description given, decomposition of the Silver carbonate will produce a silver residue with the given mass.
  • The other mass that seems lost can be examined to be given off as carbon dioxide gas which is the other product of the reaction and oxygen.
  • Therefore, since the products are silver, carbon dioxide and oxygen, the remaining mass is that of the carbon dioxide and oxygen. It is not lost.

Determine the resulting pH when 75 mL of 0.05M HBr is reacted with 74 mL of 0.075 M KOH
Sunny_sXe [5.5K]

Answer:

pH = 12.08

Explanation:

  • H⁺ + OH⁻ → H₂O

First we <u>calculate how many moles of each substance were added</u>, using <em>the given volume and concentration</em>:

  • HBr ⇒ 0.05 M * 75 mL = 3.75 mmol HBr
  • KOH ⇒ 0.075 M * 74 mL = 5.55 mmol KOH

As HBr is a strong acid, it dissociates completely into H⁺ and Br⁻ species. Conversely, KOH dissociates completely into OH⁻ and K⁺ species.

As there are more OH⁻ moles than H⁺ moles (5.55 vs 3.75), we <u>calculate how many OH⁻ moles remain after the reaction</u>:

  • 5.55 - 3.75 = 1.8 mmoles OH⁻

With that<em> number of moles and the volume of the mixture</em>, we <u>calculate [OH⁻]</u>:

  • [OH⁻] = 1.8 mmol / (75 mL + 74 mL) = 0.0121 M

With [OH⁻], we <u>calculate the pOH</u>:

  • pOH = -log[OH⁻] = 1.92

With the pOH, we <u>calculate the pH</u>:

  • pH = 14 - pOH
  • pH = 12.08
