The standard Gibbs free energy of formation of ZnO from Zn is lower than that of CO2 from CO. Therefore, CO cannot reduce ZnO to Zn. Hence, Zn is not extracted from ZnO through reduction using CO
I assume you meant to write convection for one of those answers. Convection is the way that heat is transferred through liquids and gases.
Answer:
3.38 moles.
Explanation:
The following data were obtained from the question:
Mass of copper (Cu) = 215 g
Number of mole of copper (Cu) =...?
The number of mole of copper (Cu) in 215 g can be obtained as follow:
Mass of copper (Cu) = 215 g
Molar mass of copper (Cu) = 63.55 g/mol
Number of mole of copper (Cu) =...?
Mole = mass /Molar mass
Mole of Cu = 215/63.55
Mole of Cu = 3.38 moles
Therefore, 3.38 moles of copper (Cu) is present in the sample.
Answer: a. 6(3x2=6)
B. 4(4x1=4)
C. 6(4(1)+2(1)=4+2=6
D. 4
E. 6(3(2)=6)
F. 4(2(1)+2(1)[2+2=4)
G. 5(5(1)=5)
H. 4(2(1)+2(1)=2+2=4)
Explanation:
Coordination number= no of ligands
= No of ligands X denticity
Denticity is nothing but type of ligands like mono,do and tetradentate ligands.
