Answer:
A) 9.60 g
B) 19.2 g
C) 28.8 g
Explanation:
A) Elemental oxygen mass is 16.00 g/mol, so in 0.600 mol of elementar oxygen there is 9.60 g
0.600 mol x 16.00 g/mol=9.60 g
B) Oxygen molecular mass is 32.00 g/mol, so in 0.600 mol of oxygen molecules there is 19.2 g
0.600 mol x 32.00 g/mol=19.2 g
C) Ozone molecular mass is 48.00 g/mol, so in 0.600 mol of oxygen molecules there is 28.8 g
0.600 mol x 48.00 g/mol=28.8 g
CuSO₄+ Zn = Cu + ZnSO₄
1 mole Zn ---------> 1 mole Cu
3.8 mole Zn ------> ?
moles Cu = 3.8 x 1 / 1
= 3.8 moles of Cu
hope this helps!
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
Answer:B
Explanation:
The metals are to the left of the linethe nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.
