Look at the equation for a displacement reaction below. What lost electrons in the reaction? Give the full name, not the symbols
garri49 [273]

Answer:

Cupric ions

Explanation:

In the single displacement reaction shown, the cupric ions lost two electrons.

    Cu²⁺  + 2e⁻ →  Cu

The replacement of a metallic ion in solution by a metal atom higher in the activity series than than the metal in solution falls into this category of reactions.

  Since Zn higher in the series, it displacements the cupric ions.

Consider the following generic reaction for which Kp = 5.51 × 105 at 25°C:
lora16 [44]

Answer:

K_c=1.35\times 10^7

Explanation:

The relation between Kp and Kc is given below:

K_p= K_c\times (RT)^{\Delta n}

Where,  

Kp is the pressure equilibrium constant

Kc is the molar equilibrium constant

R is gas constant

T is the temperature in Kelvins

Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)

For the first equilibrium reaction:

2R_{(g)}+A_{(g)}\rightleftharpoons2Z_{(g)}

Given: Kp = 5.51\times 10^5  

Temperature =  25°C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

T = (25 + 273.15) K = 298.15 K  

R = 0.082057 L atm.mol⁻¹K⁻¹

Δn = (2)-(2+1) = -1  

Thus, Kc is:

5.51\times 10^5= K_c\times (0.082057\times 299)^{-1}

K_c\frac{1}{24.535043}=551000

K_c=13518808.69=1.35\times 10^7
