Answer: 6 mol Li
Explanation:
The first step is to balance the equation.
2Li+Cl₂⇒2LiCl
We would need our conversions to find the amount of moles of Li needed to produces 6 mol LiCl.
Answer:
22.715 moles of oxygen are used
Explanation:
Given data:
Number of moles of ethane = 6.49 mol
Number of moles of O₂ required = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Now we will compare the moles of oxygen with ethane.
C₂H₆ : O₂
2 : 7
6.49 : 7/2×6.49 = 22.715 mol
Thus, 22.715 moles of oxygen are used.
Three ways water reaches from earth to atmosphere are
1. direct evaporation from the water bodies like sea,river,oceans
2. moisture from the land(you must have seen land dries out)
3.moisture from the plant(small capillaries from the plants sucks water from land n goes to atmosphere in form of vapour from leaves)
Answer:
C. Degree of ionization
Explanation:
The strength of an acid or a base is determined by how many H+/H3O+ or OH- ions are dissociated in solution. Therefore, it's describing the degree of ionization.
Example: HCl is a strong acid because in water it will pretty much 100% dissociate into H+ and Cl- ions.
