Answer : The balanced two-half reactions will be,
Oxidation half reaction :
Reduction half reaction :
Explanation :
Voltaic cell : It is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy. It is also known as the galvanic cell or electrochemical cell.
In the voltaic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.
The given redox reaction is:
The balanced two-half reactions will be,
Oxidation half reaction :
Reduction half reaction :
Answer:
about the same
Explanation:
Thermal energy is constant at a certain temperature in general. The energy is denoted by
Where,
is the Boltzmann constant
T is the absolute temperature
Given that the balloon filled with nitrogen gas and the crystal of sugar are at room conditions means that they have same conditions and thus they will possess same energy irrespective of the states of the matter.
Thus,
The thermal energy of the sugar molecules is <u>about the same</u> as that of nitrogen molecules.
Answer: d) 164.9 g
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of require = 25 moles of
Thus 0.412 moles of will require=
of
Mass of
Thus 164.9 g of oxygen is consumed.
