27. A spray can is used until it is empty except for the propellant gas, which has a pressure of 1344 torr at 23 °C. If the can is thrown into a fire (T = 475 °C), what will be the pressure in the hot can?

In order to produce solid iron, it first must bc processed from its orc, Fe2O1, in a blast furnace. During operation, CO gas (flue gas) is introduced into the furnace at 1650 °C and a pressure of 250 kPa. In this process flue gas reduces iron to its elemental form in the following reaction: 41. Fe;O30) COg Fe+ COz At one point in this process 256.0 L of CO was used to reduce iron ore. Assuming a complete reaction, how many grams of solid iron can be produced. Balanced chemical equation: Mass of Fe (in grams)

The number of moles of CO2 in that last equation was 0.119 moles.

Pls help ASAP.

For the following reaction: C3H8(g) + 3CO₂(g) + 4H₂O(1) 502(g) The change in gaseous moles, An = To maximize the product yield, the volume of the container should ◆ , so that the pressure will be (> →

PV=nRT R=0.0821 atm•L/mol•K °C + 273.15 = K 1 atm = 760 mmHg Many metals produce hydrogen gas when dropped in water. For example: Ca (s) +2 H20 (1) → Ca(OH)2 (aq) + H2(g) How much hydrogen gas (in liters) would be produced from dropping 5.0 grams of Calcium into an excess of water, at 25°C and 755 mmHg?

Use the ideal gas equation to calculate the number of moles of hydrogen gas produced from a reaction between hydrochloric acid, HCl, and magnesium metal in which 12.0 liters of gas was collected at 22.0 C with a barometric pressure of 761.09 torr. The gas was collected over water with a vapor pressure pf 19.83 torr. R= 82.1 atm mL/mol K     or       R= 0.0821 atm mL/mol K

Some of the gas was released as the temperature was increased to 33.1 °C, so the final pressure in the container was reduced to 1.50 atm. How many moles of the gas sample are present at the end?
