Question

can you guys help?

Sapling Learning this question has been customized by Ma Joy Heising at Massachusetts College of Pharmacy & Health scie At 1 atm, how much energy is required to heat 75.0 g of H2O(s) at-24.0 ℃ to H2O(g) at 157.0-C? STRATEGY 1. Calculate the energy for each temperature change or phase change individually a. the energy needed to heat 75.0 g of H20(s) from-24.0 C to its melting point. b. the energy needed to melt 75.0 g of H20(s) at its melting point. c. the energy needed to heat 75.0 g of H20() from the melting point to the boiling point. d. the energy needed to boil 75.0 g of H20() at its boiling point. e, the energy needed to heat 75.0 g of H2O(g) from the boiling point to 1570°C. 2. Sum the energies from each step and convert to kilojoules. Step 1: g-cl 24.0 !(24.0 g)|2.087 g o c °C)-3760 °C)-3760 J Heat.-m-&T. SH= (75.0 ΔΤ. SH. 75.0 g) 2.087 a Heah" m .

Answer 1

Sum of individual energies in J = 237710

Sum of individual energies in kJ = 237.71
