You computed the specific heat for each of the four metals using the formula below: Check all items that you used, either directly or indirectly, each time you did this computation.
the first law of thermodynamics (heat lost by a metal equals the heat gained by the water)
a) the ability of heat to flow from a hot object to a cooler one
b) masses for the metal and the water in the calorimeter
c) temperature changes for the water and the metal
d) the known specific heat of the water

i think so it’s will be b yes i believe its

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
