You need to calculate the enthalpy change (AH) of the reaction A + B → C. How can the enthalpies given for the reaction steps below be combined to
give the overall change in enthalpy?
A+B →D
C+ B>D
ΔΗ,
ΔΗ,
Ο Α. ΔΗ = ΔΗ, + 2ΔΗ,
B. AH = AH - AH2
O C. AHN AH,+AH2
O D. AH = AH2-AH,

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Use the periodic table to complete this equation that represents nuclear fission processesun - ba c 3 n

Which of the following describes qualitative data? a) recording the temperature of a solid as it is warmed. b) noting the color of a solution as it is heated. c) measuring the volume of an object by water displacement. d) taking the mass of an object using a balance.
