Answer:
Oxygen
Explanation:
Oxygen has six valence electrons and therefore always gains electrons in order to gain a full octet.
Answer:
In a lab guide, the key results are those that support my working hypotheses or serve to reject these assumptions. Moreover, the key results may also be other discoveries that are important to understand the processes and/or mechanisms investigated in the experiment.
In my experience, the best way to summarize the key results is to create diagrams and illustrations that enables me to study relationships between different data
Explanation:
Answer:
First one: Yes, It can be negative.
Explanation:
First one: The reason you can have negative acceleration is that acceleration can slow down, or decelerate, causing the negative acceleration.
Answer:
x = 35.453 amu. CHLORINE
Explanation:
Abundance of X³⁵ = 75.77%
Abundance of X³⁷ = 24.23%
Atomic mass of X³⁵ = 34.968852 amu
Atomic mass of X³⁷ = 36.965903 amu
Average atomic mass = ?
Solution:
Average atomic mass of carbon = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass of carbon = (34.968852 × 75.77)+(36.965903 ×24.23) /100
Average atomic mass of carbon= 2649.59 + 895.684 / 100
Average atomic mass of carbon = 3545.274 / 100
Average atomic mass of carbon = 35.453 amu.
x = 35.453 amu. CHLORINE
