OK,lisen to me slowly,
all define you.all thing
1.Look at peridoic table which one is solid or others.
For example:hydrogen is air.
And you gonna explain what is hydrogen,
2.After look periodic table you will be able to know every element.
3.Dont forget to check your homework.!!
Answer:
At temperatures greater than 756 °C this reaction is spontaneous under standard conditions.
Explanation:
Let's consider the following reaction.
C(s) + H₂O(g) ⇄ CO(g) + H₂(g)
The reaction is spontaneous when the standard Gibbs free energy ΔG° < 0. ΔG° is related to the standard enthalpy of the reaction (ΔH°) and the standard entropy of the reaction (ΔS°) through the following expression.
ΔG° = ΔH° - T.ΔS°
If ΔG° < 0
ΔH° - T.ΔS° < 0
ΔH° < T.ΔS°
T > ΔH°/ΔS° = (131.3 × 10³ J/mol)/(127.6 J/K.mol) = 1029 K
The temperature in Celsius is:
°C = K - 273.15 = 1029 - 273.15 = 756 °C
Answer:
5.22 x 10^-5
Explanation:
5.22 x 10^-3 x 10^-2 = 5.22 x 10^-5
