Answer:
Explanation:
4FeS₂ + 11O₂ → 2Fe₂O₃ + 8SO₂.
4 moles of FeS₂ reacts with 11 moles of O₂
8 moles of FeS₂ reacts with 22 moles of O₂
Moles of O₂ available is 15 .
So O₂ is in short supply .
So O₂ is the limiting reagent.
Option (c) is the right choice.
Assuming ideality:
PV=nRT
Pv= (mass/molarmass)RT
Solve for the mass :-)
Answer:
Here's ya idea: Can the food we eat affect our heart rate?
Explanation:
274 amu
Explanation:
Atomic weight of Na = 23
Atomic weight of Sio3 = 76
then,
molecular weight of Na2Sio3 = add 23*2 and 76*3
= 46 and 228
= 274 amu
The amount of heat required to melt the iceberg at 9.58 * 10¹⁸ kJ.
<h3>What is the amount of heat required to melt an iceberg that has a volume of about 3.1 x 1013 m³?</h3>
The heat required to melt a unit mass of ice is known as the latent heat of fusion.
The latent heat of fusion of ice of 1 kg= 334 kJ of heat
Mass of iceberg = 3.1 x 10¹³ m³ * 917 kg = 2.8427 * 10¹⁶ kg
Amount of heat required = 2.8427 * 10¹⁶ * 334 = 9.58 * 10¹⁸ kJ.
Therefore, the amount of heat required to melt the iceberg at 9.58 * 10¹⁸ kJ.
