What volume of hydrogen gas is produced when 69.0 g of iron reacts completely according to the following reaction at 25 °C and 1 atm? iron (s) + hydrochloric acid(aq)iron(II) chloride (aq) + hydrogen(g)

how many liters of carbon dioxide?

The teacher is mostly talking about the distillation of a mixture

The correct answer would be b) volume versus temperature, because they are also directly proportional.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

Oxygen= 88ghydrogen= 12g
