Answer:
record only the maximum and minimum temperatures they are exposed to
Answer:
Explanation:
Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius ( ∘ C ^\circ\text C ∘Cdegrees, start text, C, end text) or Kelvin ( Kstart text, K, end text), and heat has units of energy, Joules ( Jstart text, J, end text).
Answer:
Explanation:
The formula for the change in freezing point ΔT_f caused by an electrolyte is
1. Calculate i
Na₂SO₄(aq) ⟶ 2Na⁺(aq) + SO₄²⁻(aq)
1 mol Na₂SO₄ gives 3 mol ions.
i = 3
2. Calculate the freezing point
(a) Change in freezing point
(b) Freezing point
Answer:
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.
