A water carbonating plant operates by providing carbon dioxide at 5.0 atm. Estimate the molar concentration of CO2 in carbonated water it produces at 25 ºC.
Given a 4.50 L container of helium at 298 K and 1.00 atm, and a 3.00 L container of argon at 298 K and 1.00 atm, write a brief statement to explain whether or not atoms of He and Ar in their respective containers have the same average speed.
How many grams of CaCl2 are needed to make 968.1 g of a solution that is 35.5% (m/m) calcium chloride in water? (Note that m/m has the same meaning as w/w.)
Calculate the mass of one oxygen atom and determine the number of oxygen atoms in a 10.00g sample of the element.
A piece of metal with a mass of 146 g is placed in a 50 mL graduated cylinder. The water level rises from 20. mL to 35 mL. What is the density of the metal?
What is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants?
Looking at the nickel complexes as an example, it is found that those formed with ammonia give the complex [Ni(NH3)6]^2+ and when formed with ethylenediamine the complex [Ni(en)3)^2+ is the result.
12.5 g of KCl (MM = 74.55 g/mol) is dissolved in enough water to make 675 mL of solution. Calculate the molarity of the KCl solution.
Draw the products(if any) expected from the treatment of each of the following compounds with ozone followed by aqueous hydrogen peroxide
Which pair is written with the first member having the higher boiling point?
(a) reversibly, (b) against a constant external pressure equal to the final pressure of the gas, and (c) freely (against zero external pressure)
A gas occupies 22.4 L at STP and 14.5L at 100 C and 2.00 atm pressure. how many moles of gas did the system gain or lose?
