predict whether a reaction will occur in each of the following. if so write the balanced chemical equation as well as the net ionic equation. Phases are all required for all species.
(a) FeSO4(aq) + SrI2(aq)---->(b) NaHSO3(aq) + HClO4(aq)---->
What mass of NO2 can be produced by the complete reaction of 40.00 g of ammonia with 98.00 g of oxygen: 4NH3 + 7O2 4NO2 + 6H2O
What mass of NaOH is needed to precipitate the Cd2+ ions from 68.0 mL of 0.500 M Cd(NO3)2 solution?
A 1- flask is filled with 1.45 of argon at 25 . A sample of ethane vapor is added to the same flask until the total pressure is 1.30 .What is the partial pressure of argon, , in the flask?
The ionization constant, Ka, for HOI(aq), hypoiodous acid, is 2.3 × 10-11. What is the pH of a 0.050 molar solution of sodium hypoiodite, which contains the hypoiodite ion?
Solid aluminum metal and diatomic chlorine gas react spontaneously to form a solid product. Give the balanced chemical equation (including phases) that describes this reaction.
Consider a system with four energy levels: 0E, 1E, 2E, 3E, where E is kT (E can be represented by epsilon and T is 100K). Assume that there are 10 particles. Provide an expression for energy, heat capacity and entropy. Plot all as a function of T
How much heat (in kJ) is evolved in converting 1.00 {mol} of steam at 160.0C to ice at -45.0C? The heat capacity of steam is 2.01 J/g*C and of ice is 2.09 J/g*C.
heptapeptide upon HCL hydrolysis produced equimolar amounts of ASP, CYS, GLU, LYS, PHE, TYR, VAL and ammonia. Exposure of the intact heptapeptide to FDNB followed by hydrolysis produced DNP-VAL
An an isothermal process, the pressure on 1 mol of an ideal monatomic gas suddenly changes from 4.00 atm to 100.0 atm at 25°C. Calculate w
Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway enzyme that results in the inactivation of that enzyme
calculate the heat change at 100 degrees Celsius and indicate whether heat was absorbed or released: a) joules to condense 10.0 g of steam; b) kilojoules to condense 76.0 g of steam; c) joules to vaporize 44.0 g of water; d) kilojoules to vaporize..
Choose the answer in which the two atoms are listed in order of increasing ionization energy
