Answer:
1. S+ O2-->So2..... synthesis reaction or direct combination.
2.. precipitation reaction
3. Displacement reaction
4. Decomposition reaction
<span>Silver oxalate dissociation equation is following:
</span><span>
Ag</span>₂C₂O₄(s) ⇄ 2Ag⁺(aq) + C₂O₄²⁻(aq)
According to reaction follows next stoichiometric ratio:
[Ag⁺] : [C₂O₄²⁻] = 2 : 1
[C₂O₄²⁻] = [Ag⁺] / 2
[C₂O₄²⁻] = (1.7×10⁻⁴)/2 = 8.5×10⁻⁵ M
So, solubility product constants for silver oxalate is:
Ksp = [Ag⁺]² x [C₂O₄²⁻]
Ksp = [1.7×10⁻⁴]² x [8.5×10⁻⁵]
Ksp = 2.46×10⁻¹²
The answer to the question Retraction. Its because the light goes around it
The numerical setup is
<span>11<span>g</span></span>CO2×1 mol CO2/44.01g CO2=0.25 mol CO2
gCO2 cancels out so it is
11 x 1 mol CO2/44.1 CO2= 0.25 mol CO2
Answer:
Solid/freezing
Explanation:
Solid has the least energy of all of the phase changes and the more energy is lost the colder its gets then water turns into a solid called ice hope i helped!
