Answer:
4.13 moles of Fe
Explanation:
Step 1: Write the balanced equation
3 CO + Fe₂O₃ ⇒ 2 Fe + 3 CO₂
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of CO to Fe is 3:2.
Step 3: Calculate the moles of Fe formed from 6.20 moles of CO
We will use the previously established molar ratio.
6.20 mol CO × 2 mol Fe/3 mol CO = 4.13 mol Fe
Answer:
There is more space between gas particles than the size of the particles.
Explanation:
This scenario can be understand by taking a very simple example. As we know that 1 mole of any gas at standard temperature and pressure occupy 22.4 liters of volume. Lets take Hydrogen gas and Oxygen gas, 1 mole of each gas will occupy same volume. Why it is so? Why same volume although Oxygen is 16 times more heavier? This is because the space between gas molecules is very large. Approximately the distance between gas molecules is 300 times greater than their own diameter from its neighbor molecules.
Answer:
97% of earth's water is in the ocean. The rest could be found underground, in glaciers and ice, and in rivers and lakes
