Answer:
1.
- shrubs are producers.
- small animals are primary if they eat plants only.
- they're both if the consumer is omnivorous
2. most plants , including trees, are producers so they can't be consumers.
- only rare plants like the venus fly trap is a consumer because they eat bugs.
Answer:
4.56×10^-10
Explanation:
Co(OH)2(s)<------->Co^2+(aq) + 2OH^-(aq)
Co^2+(aq) + 6NH3(aq) ---------->[Co(NH3)6]^2+(aq)
Overall equation:
Co(OH)2(s)+ 6NH3(aq) ---------->[Co(NH3)6]^2+(aq) + 2OH^-(aq)
The increased solubility of the cobalt salt in the presence of ammonia is as a result of the formation of the hexammine cobalt II complex shown above.
Knet= Ksp×Kf
Ksp of Co(OH)2= 5.92 × 10^-15.
Kf= 7.7 x 10^4
Knet= 5.92 × 10^-15 × 7.7 x 10^4
Knet= 4.56×10^-10
Note Knet is the equilibrium constant of the overall reaction.
Radiation: Heat from the stovetop.
Conduction: Heat from Stove to Pot.
Convection: Water boiling.
I will now take my points.
Ca(OH)2 -------> CaO + H2O
ratio is 1 : 1
CaO Mr= 56g
15/56 = 0.268 mol (mols of CaO in 15g)
Ca(OH)2 Mr= 74g
0.268x74= 19.83g (required amount of Cash(OH)2)
Chlorophyll, it is the pigment in plants that absorbs light in photosynthesis
