0.5 moles, though not a verified answer hope it helps! :D
The time it takes for dissolvable or absorbable stitches to disappear can vary. Most types should start to dissolve or fall out within a week or two, although it may be a few weeks before they disappear completely. Some may last for several months
Answer:
b) At equilibrium, equal amounts of products and reactants are present.
Explanation:
At equilibrium , the ratio of product of concentration of products and product of concentration of reactants is constant .
A + B ⇄ C + D
[C] [ D] / [ A ] [ B ] = Constant
So, the statement ( b ) is false .
All other statements are true .
Answer:
ΔG° = 1022. 8 kJ
Explanation:
ΔH° = –199 kJ/mol
ΔS° = –4.1 J/K·mol
T = 25°C = 25 + 273 = 298K (Converting to kelvin temperature)
ΔG° = ?
The relationship between these varriables are;
ΔG° = ΔH° - TΔS°
ΔG° = –199 - 298 (–4.1)
ΔG° = -199 + 1221.8
ΔG° = 1022. 8 kJ
Answer:
The change of state requires energy.
Explanation:
Instead of the energy changing the temperature the heat energy is used by changing its form.
