A scientist measures the standard enthalpy change for the following reaction to be -889.4 kJ :
2NH3(g) + 3 N2O(g) 4N2(g) + 3 H2O(g)
Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of N2O(g) is ______kJ/mol
convert back to molarity. And since it is a strong acid, you would just take the -log(KOH or OH-) then subtract this number from 14. From this I get 11.85, however the answer is 10.98. Can somebody tell me where I'm going wrong in detail?
on't 2 and 3 have multiple answers? I think I'm only supposed to have one, though? How do you differentiate using the water solubility chart?
What is the purpose of running both Dalton Vll mixed markers and lanes with individual markers on SDS-PAGE?
Cars were timed by police radar as they passed in both directions below a bridge. Their velocities (kilometres per hour, numbers of cars in parentheses) to the east and west were as follows
In a test tube, 10 mL of 0.100 M KI and 10 mL of 0.100 M Na2CO3 are mixed. Next, 0.10 M lead nitrate is added drop wise. What will be the concentration of CO3 2- when PbI2 first starts to precipitate? Ksp (PbCO3) = 1.5 x 10^-13 Ksp (PbI2) = 8.7 x 1..
Pressure is gradually decreased from 87.7mL to 42.6mL. What is the final pressure of ammonia if there is no change in pressure?
Write an equation for this reaction? which species acts as the nucleophile? Which species acts as the electrophile?
Solute S has a partition coefficient of 6.1 between water (phase 1) and hexane (phase 2). A 74.0 mL solution of S in water is extracted six times with 12.0 mL of hexane. Calculate the fraction of S remaining in the aqueous phase.
A sample of pure NO2 is heated to 334 degree C at which temperature it partially dissociates according to the equation 2NO2(g)-->2NO(g)+O2(g)
