Use the given half reactions to "construct" an electrolytic cell. Zn^2+ + 2 e^--------->Zn E°cell = -0.76 V Cu^2+ + 2 e^-----
Neko [114]

Answer:

See explanation and image attached

Explanation:

The standard cell potential at 298 K is given by;

E°cathode - E°anode

Hence;

E°cell = 0.34 V - (-0.76 V)

E°cell = 0.34 V + 0.76 V

E°cell = 1.1 V

To reduce Zn^2+ to Zn then Zn must be the cathode, hence;

E°cell = (-0.76 V) - 0.34 V

E°cell = -1.1 V

Why is the cell theory so important??
Kamila [148]

Answer:

yes

Explanation:

The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.

Consider the combustion of h2(g) 2h2(g)+o2(g)→2h2o(g). If hydrogen is burning at the rate of 0.49 mol/s, what is the rate of con
mamaluj [8]

Answer : The rate of consumption of oxygen = 0.245 mol/s

Solution :  Given,

                 Rate at which Hydrogen burns = 0.49 mol/s

                 The Reaction is,

                       2H_{2}(g)+O_{2}(g)\rightarrow 2H_{2}O(l)

    In this reaction,  2 moles of hydrogen react with the 1 mole of oxygen.

    The rate at which oxygen burns is equal to the half of rate at which hydrogen burns.

     Rate at which Oxygen burns = \frac{1}{2} × 0.49 mol/s

                                                      = 0.245 mol/s

Why is co2 hard to break apart than h2o
Sergeu [11.5K]
In CO2 the dipole moments cancel out, while in H20, they don’t, making it polar. In C02, both oxygens are more electronegative than the carbon, but they pull equally apart from one another, so there is no dipole moment (the pulls cancel)
