A device in your school lab releases gas at a rate of , which means 0.25 liter of gas is released every second. The density of the gas is , which means that there are 4.3 grams of the gas in one liter. Set up the calculation to find the number of seconds it will take for the device to release 154 grams of the gas.

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

What does the mass of 0.7891 mol of ferric oxide (fe2o3)

The number to the right of an element's symbol (ex. c-12) identifies the of an isotope.
