1, 3, 4, and 5
Explanation:
the number would be the dot order!
Answer:
Explanation:
The relation between equilibrium constant and Ecell is given below .
E⁰cell = (RT / nF ) lnK , F is faraday constant T is 273 + 25 = 298 K
E⁰cell = 1.46 - 1.21 = .25 V
n = 2
Putting the values
.25 = (8.314 x 298 lnK) / (2 x 96485 )
lnK = 19.47
K = 2.85 x 10⁸
2 )
Change in free energy Δ G
Δ G ⁰ = nE⁰ F
n = 4
E⁰ = .4 + .83 = 1.23 V
Δ G ⁰= 4 x 1.23 x 96485
= 474706 J / mol
3 )
E⁰cell = (RT / nF ) lnK
n = 2
1.78 = 8.314 x 298 lnK / 2 x 96485
lnK = 138.638
K = 1.62 x 10⁶⁰
Answer:
Moles = mass(m) / Molar mass (M)
A. 1.24g of Zn
m = 1.24g
M = 65.4 g/mol
moles of Zn = 1.24g/ 65.4g/mol
= 0.01896mol
B. 28.1 g Ar
m = 28.1g
M(Ar) = 39.9g/mol
moles of Ar = 28.1g/39.9g/mol
= 0.7043 mol
C. 84.0 g Ta
m = 84.0g
M(Ta) = 181g/mol
moles of Ta = 84.0g/181g/mol
= 0.4641 mol
D. 2.29x10^-2 g Li
m = 2.29x10^-2 g
M(Li) = 6.9g/mol
moles of Li = 2.29x10^-2 g / 6.9g/mol
= 0.0033 mol

Non metallic elements pull electrons from metallic elements so effectively during a reaction because they have a tendency to gain electrons and tend to be small in size.
<span>Non metallic elements have higher electronegativities than metals. The atoms of nonmetals tend to gain electrons in order to acquire a noble gas electron configuration. This gives them a net negative electric charge. </span>
