Final answer:

To heat the ice to 0 degrees Celsius, 5398.8 joules of energy are necessary.

Step-by-step explanation:

To calculate the energy required to heat the ice to 0 degrees Celsius, we can use the equation:

Q = m * c * ΔT

Where Q is the heat energy, m is the mass of the ice, c is the specific heat of ice, and ΔT is the change in temperature.

Given that the mass of the ice is 46.0 g, the specific heat of ice is 2.1 J/g, and the change in temperature is 58 degrees Celsius, we can plug in these values into the equation to find the heat energy:

Q = 46.0 g * 2.1 J/g * 58 °C

= 5398.8 J

Therefore, 5398.8 joules of energy are necessary to heat the ice to 0 degrees Celsius.
