How much work is done in the water electrolysis reaction above?  Assume room temperature conditions.  7.5 kJ   - 7.5 kJ   -2.5 kJ   2.5 kJ

0.8 m3 of saturated liquid water at 200°C is expanded isothermally in a closed system until its quality is 61%. Determine the total work produced by this expansion in MJ. IMPORTANT INSTRUCTION: Put your answer in the text box up to two decimal places or as a whole number.Please note you don't need to write the unit for your answer. Just write the numerical value up to two decimal places.

Consider the explosion of a hydrogen balloon. 2H2(g)  + O2(g)   ⟶ 2H2O(g) How much work is done and is it on or by the system?  - 7.5 kJ   -2.5 kJ   7.5 kJ   +2.5 kJ

.Question 6Consider a pump with a mass flow rate of water of 5 kg/s. The water enters at 99 °C and 9999 kPa and leaves at 150 °C and 15000 kPa. What is the specific work of the pump? Assume the process is adiabatic. 1 point219 kJ/kg-1095 kJ/kg1095 kJ/kg-219 kJ/kg

6 kJ of work is done by a force in moving an object uniformly through 120 m in 1 minute. The force applied is:a.720 Nb.20 Nc.50 Nd.12 N

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 5.10kg of water at 24.3°C. During the reaction 125.kJ of heat flows out of the bath and into the flask.Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18·J·g−1K−1. Be sure your answer has the correct number of significant digits.
