A 7.25g sample of solid sodium hydroxide was dissolved in a calorimeter in 199.4g of water. The temperature of the water rose from 22.1°C to 37.5°C. Calculate the enthalpy per mole of sodium hydroxide for the dissolution process. Assume the specific heat of the solution is the same as that for pure water.
Given that 4NH3(g)+5 O2(g)---> 4NO (g)+ 6H2O (g), If 8.2 moles of NH3 React with sufficient oxygen, how many moles of water will be formed?
the temperature of a 2.0 liter sample of heluim gas at STP is increased to 27 celsius and the pressure is decreased to 80.0 kPa. what is the new volume of the helium sample.
Assuming the solution has a heat capacity of 4.18 J/°C·g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
What is the concentration of ammonium ion in a pH 9 solution that forms when concentrated NaOH is added
Write the dissolution reaction for the ionic solids below. Use the lowest possible coefficients. Include states-of-matter under the given
The structures of the disulfides (MS2) show an apparently unusual trend, proceeding from left to right across the transition series. On the left side (TiS2, ZrS2, MoS2, etc.)
The numbers above are also the only numbers I am given. I do not have delta G's of molar G's. If you have an answer that solves for the G's and shows me step by step how to solve the problem, you will get five stars.
