Higher chemistry excess questions
WebCalculating Product Formation Based on the Limiting Reactant Practice Question: We burn 96 grams of magnesium in excess air. What mass of magnesium oxide is formed? 1.Write out a balanced equation. To calculate the mass, we firstly need to write out the balanced equation. Magnesium + oxygen -> Magnesium oxide 2Mg + O 2 -> 2MgO 2. Use the table. WebMolar Volume. At room temperature and pressure, the volume occupied by one mole of any gas was found to be 24 dm 3 or 24,000 cm 3. This is known as the molar gas volume at RTP. RTP stands for “room temperature and pressure” and the conditions are 20 ºC and 1 atmosphere (atm) From the molar gas volume the following formula triangle can be ...
