Supersaturated is when a solution holds more solute than can normally hold/ normally be dissolved.
The answer is A because I did this before
The periodic table so she can see the number of valence electrons to put in her calculations
Answer:
Sr(s)+2H20(l)--->Sr(OH)2(aq) + H2(g)
(s) denotes a solid
(l) (looks like an I, but it is an L,) denotes a liquid
(g) denotes a gas
(aq) denotes an aqueous solution, just something dissolved in water
Answer:
Option B. 2096.1 K
Explanation:
Data obtained from the question include the following:
Enthalpy (H) = +1287 kJmol¯¹ = +1287000 Jmol¯¹
Entropy (S) = +614 JK¯¹mol¯¹
Temperature (T) =.?
Entropy is related to enthalphy and temperature by the following equation:
Change in entropy (ΔS) = change in enthalphy (ΔH) / Temperature (T)
ΔS = ΔH / T
With the above formula, we can obtain the temperature at which the reaction will be feasible as follow:
ΔS = ΔH / T
614 = 1287000/ T
Cross multiply
614 x T = 1287000
Divide both side by 614
T = 1287000/614
T = 2096.1 K
Therefore, the temperature at which the reaction will be feasible is 2096.1 K
