A 3.0 l sample of helium gas is stored in a rigid, still container at 25 degrees Celsius and 1.0 ATM pressure. The pressure is increased to 1.5 ATM and the temperature is increased to 125 degrees Celsius. What is the new volume of the gas?

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

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!

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
