The amount of liquid is measured in L. As the unit Lm is only used when measuring the mass liquid fraction.
Answer:
Explanation:
2H₂O₂ ⟶ 2H₂O + O₂
A catalyst is a substance that speeds up a reaction but can be recovered unchanged at the end.
Thus, at the end of the reaction I would expect to find H₂O and MnO₂ in the container.
Water is not listed in any of the options, so I will have to choose .
A, B, and D are wrong. They are not reactants, products, or catalysts.
Answer:
The answer to your question is :
a) Abundance of Li-6 = 7.49
b) Abundance of Li-7 = 100-7.49 = 92.5
Explanation:
Data Isotopes Mass Abundance
Li-6 6.015 amu y
Li-7 7.016 amu 100 -y
Lithium atomic mass = 6.941
6.941 = (6.015y) + (7.016)(100-y) /100
6.941 = (6.015y + 701.6 - 7.016y) / 100
6.941 x 100 = 6.015y - 7.016y + 701.6
694.1 -701.6 = - 1.001y
-7.5 = -1.001 y
y = 7.49
Abundance of Li-6 = 7.49
Abundance of Li-7 = 100-7.49 = 92.5
