Answer:
2.2×10^8
Explanation:
Cu(OH)2(s)<---------> Cu^2+(aq) + 2OH^-(aq) Ksp=2.2 x 10 ^-20
2H3O^+(aq) + 2OH^-(aq) <-------> 4H2O(l). Kw= 1×10^14
Cu^2+(aq) + 4H2O(l) <--------> [Cu(H2O)4]^2+(aq)
Overall ionic reaction:
Cu(OH)2(s) +2H3O^+(aq) <---------> [Cu(H20)4]^2+(aq)
Equilibrium constant for the reaction: Ksp×Kw= 2.2 x 10 ^-20 × (1/(1×10^-14))^2
Keq= 2.2×10^8
Kw= ion dissociation constant of water
Answer:
carbon dioxide CO₂
Explanation:
Each gas has a characteristic boiling point. You can separate a random sample of gases by gradually cooling the sample until each component gas liquifies. Some compounds, such as CO₂ never liquify. Instead, they turn directly into solids.
Answer: Now that you see to some extent bit about place nonrenewable fuel sources come from, can you analyze in what way or manner the Sun’s light strength is ultimately being the reason for the strength in fossil fuels? Describe the way that light strength must enjoy become the synthetic strength in fossil fuels and therefore energetic energy. (Hint: Think about by means of what plants in an environment take their energy.)
Answer:
Earthquake engineering
Aerospace engineering
Coastal engineering
Hydraulic engineering
environmental engineering
construction engineering
structural engineering
Constant rain and humidity
