c. Moles of magnesium reacted. The number of moles of magnesium reacted is based on the mass of magnesium taken and the molar mass of magnesium (24.31 g per mole of Mg). For the data above, calculate the number of moles of magnesium reacted, then click here to check your answer.
Magnesium is capable of reducing water and releasing highly flammable hydrogen gas: Mg (s) + 2 H 2 O (l) → Mg(OH) 2 (s) + H 2 (g) Therefore, water cannot extinguish magnesium fires. The hydrogen gas produced intensifies the fire. Dry sand is an effective smothering agent, but only on relatively level and flat surfaces.
Oil and gas production are among the main culprits of air pollution - one of the world's biggest killers according to the United Nations. Although the health threats from oil and gas production are very real, the federal government continues to push for fossil fuel drilling near communities.
Without water, we would not be. Water is the basis of all life as we know it. But what exactly makes it so uniquely capable of supporting life? This is because of the phenomenon wherein opposite charges attract one another: because each individual water molecule has both a negative portion and...
The magnesium determines how much Magnesium oxide is produced. It would be good to get .0608 moles of MgO, but there isn't enough magnesium. Sounds like an acid metal reaction to produce hydrogen gas, so I will assume you meant hydrochloric acid. Complete reaction indicates aluminum...
A student reacted 0.20 g of calcium and 0.20 g of strontium separately with 250 cm3 of water. The student measured the volume of gas produced from each reaction. The student’s results are shown below. metal calcium strontium volume of gas / cm3 120 55 (i) Name the gas produced.
Magnesium metal reacts with hydrochloric acid to produce hydrogen gas H2 Mg +. Jiskha Homework Help. Magnesium metal reacts with hydrochloric acid to produce hydrogen gas H2 Mg + 2HCl ----> MgCl + H2 Calculate the volume (in liters) of hydrogen produced at 33 degrees C and 665 mmHg from 0.0840 mol Mg and excess HCl.
