In the areas where water is NOT undergoing a phase change, what is the energy being used to do?
For a gaseous reaction, standard conditions are 298 K and a partial pressure of 1 atm for all species. For the reaction C2H6 (g)+ H2 (g) -> 2CH4
Explain what is the carbon dioxide generation rate, in lb CO2 per MWe-hr and what percentage reduction is needed to meet the U.S. EPA's proposed emission standard of 1,000 lb CO2per MWe-hr. Explain how might the reduction be achieved
Explain how rapidly would the subsequent particles be moving if they all had the identical wavelength as a photon of orange light (λ = 625.0 nm) with an electron mass of 9.109ε-28g
An element in one of the 10 smaller groups near the middle of the periodic table is known as the?
Can someone name a complexing agent that only binds to Mg(II) and is fluorescent as well. Or can you disprove that Chromonycin A3 is not selective to Mg(II)
Suppose 25.0 g of solid NaOH is added to 1.5 L of an aqueous solution that is already 2.4 M in NaOH. Then water is added until the final volume is 4.00 L. Determine the concentration of the NaOH in the resulting solution.
A 1.00 L buffer solution is .250 M in HF and .250 M in LiF. Calculate the pH of the solution after the addition of .15 moles of solid HI. Assume no volume change. Ka for HF at 25C is 3.5x10^-4
How do I determine if an ionic compound has the crystal structure of a simple cubic, a body-centered cubic or a face-centered cubic. E.g. NaCl has a structure based on a face-centered cubic lattice. Why is that
Using the moles of air, temperature of air and slope of the Air Volume vs. 1/pressure graph, calculate the ideal gas constant.
Complete the following calculation: a student wants to react mg(s) with 100ml of 1.5M hcl, but the intent is to have all the mg(s) react, while leaving 50% of the Hcl unreacted. How much Mg i grams should the student add to the HCl
A gas mixture contains 8.10g of N2, 1.70 g of H2, and 14.70 g of CH4. what is the mole fraction of H2 in the mixture
