A system comprised of 2.900×10^1 g of Ne(g) cools from 170.0°C to 45.0°C at a constant pressure of 5.5 atm. The molar heat capacity at constant pressure for Ne(g) is 20.80 J K?1 mol?1. calculate q,w,delta E, ANDdelta H
Analysis of corrosion mechanisms and preventative measures
Use net ion equations to show how ammonium chloride (NH4Cl) is acidic and sodium acetate
Pretend that the HCl of this reaction is used in the neutralization of 45mL of a solution of Ga(OH) 3. What was the molarity of the Ga(OH)3 solution
16.2g iron(III) chloride reacts with 3.33g NH2OH in acid to produced N2O gas. a) Write a balanced, net ionic equation.
Calculate the mass fraction of sulfuric acid in the product solution. b.) Taking 100 kg of the 20% feed solution as a basis, draw and label a flowchart of this process, labeling both masses and volumes, and do the degree-of-freedom analysis. Calcu..
Suppose that Mt=Lt=0.1M (exactly) and the pH is somehow fixed at 5.00. (This means that the charge balance no longer applies.) Use the equilibria and the two mass balances to find the concentrations of ML+, M+2, L-, HL.
Determine the number of milliliters of 0.0300 M unknown metal hydroxide solution that is required to neutralize 25.00 mL of 0.0150 M phosphoric acid.
What is the sum of the stoichiometric coefficients when the reaction is balanced to lowest common denominator
What are the pH values if you take into account that the 8.00 mL of 0.10 M Acid was first diluted with 100 mL of water
What is mass (in g) of copper can be recovered from 49.9 mL of a 0.628 M solution of copper(I) chloride and excess hydrogen
Explain why selectivity in isocratic HPLC system ideally should not depend on eluent composition. Use thermodynamic derivation to support your explanation.
An individual's blood alcohol content (% alcohol in blood as measured mass per volume = mass of alcohol per volume of blood) was 0.15. If we assume the individual drank all of the alcohol at once
