Does the iron in the Fe(NH4)2SO4 solutions function as an oxidizing agent or a reducing agent. Please explain
If all 0.44 gigatons CO2 remain in the atmosphere and spread around the atmosphere evenly, what concentration in ppm would it constitute?
Classify the substances according to the strongest solute-solvent interaction that will occur between the given substances and water during dissolution.
An isotonic solution is described as 0.92% NaCl (g/mL). Would this also be the required concentration for isotonic solutions of other salts, such as KCl, MgCl2,
There are two different schemes you could use to synthesize 4-ethyl-3-heptanol using a Grignard reagent and a carbonyl-containing compound
If 158 of wet hydrogen is collected over water at 24 and a barometric pressure of 736 , how many grams of hydrogen have been consumed.
What are the pressures, temperatures, enthalpies, and mass densities of the substance at the beginnings and ends of the processes?
Justify your answer by calculating the changes in the vapor pressure of pure water vs. salty water at 100 °C. Assume you add 100.0 g of salt to 1.00 liter (1000 mL) of water. Vapor pressure of pure water is 760 mmHg. Assume density of water as 1 g..
sunlight with a wavelength greater than 240nm. What is the energy available for the dissociation of molecular oxygen at 200nm?
Use the Nernst Equation to calculate Ecell at 25 C for electrolysis of aqueous sodium chloride if the concentration of chlorine in the brine solution is 4.5 M and the partial pressure of Cl2 is 0.001 atmospheres.
More gas is then added to the container until it reaches a final volume of 13.9 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.
A moth-ball, composed of naphthalene (C10H8), has a mass of 1.32 g. How many naphthalene molecules does it contain?
reaction vessel initially contains 153 torr of water at 700.0 {\rm K} in contact with excess solid carbon, find the percent by mass of hydrogen gas of the gaseous reaction mixture at equilibrium.
