Answer:
Temperature = 818 K
Explanation:
The given reaction is:
The change in enthalpy is: ΔH°= -109 kJ
The change in entropy is : ΔS° = -133.2 J/k = -0.1332 kJ/K
Based on the Gibbs-Helmholtz equation the standard free energy change is given as:
At equilibrium ΔG° = 0. therefore:
1.0 mg/mL
a) Convert <em>grams to milligrams
</em>
Mass = 1.0 g × (1000 mg/1 g) = 1000 mg
b) Convert <em>litres to millilitres
</em>
Volume = 1 L × (1000 mL/1 L) = 1000 mL
c) Calculate the <em>density
</em>
ρ = mass/volume = 1000 mg/1000 mL = 1.0 g/mL
Answer:

Krypton is an element in the periodic table with an atomic number of 36.
The symbol for Krypton is Kr.
Answer:
x=7
Explanation:
3x-3=18
-3 moves over the 18 side and becomes +3.
18 + 3 =21
3x=21
now you need to divide 3 with 21 giving you 7
