forsale [732]

Answer:

Explanation:

Half equation:

I. Au3+ + 3e- --> Au

II. 2I- --> I2 + 2e-

Au3+ + 3e- --> Au. ×2

2I- --> I2 + 2e- ×3

2Au3+ + 6e- --> 2Au

6I- --> 3I2 + 6e-

Overall equation

Answer:

The expression of an equilibrium constant will given as:

$K_c=\frac{[NH_3]^2}{[N_2][H_2]^3}$

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_{eq}$

K is the constant of a certain reaction when it is in equilibrium

$N_2 (g) + 3 H_2 (g)\rightleftharpoons 2 NH_3 (g) + heat$

The expression of an equilibrium constant will given as:

$K_c=\frac{[NH_3]^2}{[N_2][H_2]^3}$

Can someone please help me with this?--20 pts!

katrin2010 [14]

Answer:

Compound B is ionic. The electronegativity difference is 2.2, which can be determined by subtracting the electronegativity of Element Y from that of Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.

Hope that helps.
