Answer:
The best answer would be:
C. The scientific method was followed because the experiment tested the hypothesis and produced reliable results.
Explanation:
The purpose of an experiment is to test the hypothesis. It is true that having an experimental group and a control group was following the scientific method but the data gathering and documentation was also part of the scientific method. So the best answer would be C.
Writing the question is not necessary. It is merely part of forming a hypothesis. The scientific method does not require many scientists to perform the experiment, but it does require that the experiment be repeatable, so it can be tested again.
Electrons are not a part of the mass number,
Tin has 50 Electrons
50 Protons, and 69 Neutrons are in a Tin Atom
Answer:
A. Predicting data that fall beyond a known data point
Explanation:
Extrapolating is unreliable because you are predicting data outside of the data range - anything could happen for the data to stop following the trend or pattern
Answer:
15.999 amu
Explanation:
15.999 amu
Explanation:
From the question given above, the following data were:
Isotope A:
Mass of A 15.995 amu
Abundance (A%) = 99.759%
Isotope B:
Mass of B = 16.995 amu
Abundance (B%) = 0.037%
Isotope C:
Mass of C = 17.999 amu
Abundance (C%) = 0.204%
Atomic mass of Oxygen =.?
The atomic mass of oxygen can be calculated by using the following formula:
Atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]
Atomic mass = [(15.995 × 99.759)/100] + [(16.995 × 0.037)/100] + [(17.999 × 0.204)/100]
Atomic mass = 15.956 + 0.006 + 0.037
Atomic mass = 15.999 amu
Therefore, the atomic mass of oxygen is 15.999 amu
