Dante drew a diagram to show how a wire uses the magnetic field of a magnet to induce an electric current. How can Dante correct
the diagram?
He can move the wire upward instead of downward.
He can connect the wire to both ends of the ammeter.
He can change the wire from coiled to straight.
He can place the wire between the poles of the magnet and not move it.

Answer:
= -457.9 kJ and reaction is product favored.
Explanation:
The given reaction is associated with 2 moles of
Standard free energy change of the reaction () is given as:
, where T represents temperature in kelvin scale
So,
So, for the reaction of 1.57 moles of ,
As, is negative therefore reaction is product favored under standard condition.
Answer: 24.1 L
Explanation:
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the sample when heated to 220.0oC and the pressure is constant is 24.1 L
