I swear, everyone just ignores my question, but I'm going to ask anyways. A beaker is filled with 5.4 grams of Oxygen gas in a fixed volume of 4.0 liters. One of the valves opened and there remains only 1.7 grams of Oxygen gas, what is the new volume of gas?

Summarize possible ways in which phases of matter could combine to form a solution.

Read the chemical equation. 2c2h2 + 5o2 → 4co2 + 2h2o which of the following statements would be correct if one mole of c2h2 was used in this reaction? one mole of oxygen was used in this reaction. five moles of oxygen were used in this reaction. four moles of carbon dioxide were produced from this reaction. two moles of carbon dioxide were produced from this reaction.

Achemical reaction is done in the setup shown, resulting in a change of mass. what will happen if the same reaction is done in a sealed container that is placed on the electronic balance?
