Answer:
Problem Details
The element europium exists in nature as two isotopes: 151Eu has a mass of 150.9196 amu, and 153Eu has a mass of 152.9209 amu. The average atomic mass of europium is 151.96 amu. Calculate the relative abundance of the two europium isotopes.
answer:
151Eu = 48%, 153Eu = 52%
Since there is more energy added as heat rises, the particles disperse and have larger movements.
Answer:
water
Acidity and basicity are usually determined in a solvent. The strongest acid in the solvent is always the conjugate acid of the solvent and the strongest base is the conjugate base of the solvent. So, in water, the strongest acid is H3O+ and the strongest base is OH- (conjugate base of water).
Options:
conduct an experiment
form a hypothesis
draw a conclusion
state the cause
Answer:
'<u>State the cause'</u> is not part of the scientific method.
Explanation:
The scientific method has three wholistic steps:
- Test the hypothesis
- Make observations from the experiment to the hypothesis
- Draw a conclusion or prediction from the experimental results.
A cause is neither a scientific term nor is it part of the processes of experimentation.
