C. She asks her lab partner which base he thinks is the hardest to study
D. She measures the temperature of a solution before and after adding H2SO4
No, it can also be less than 1 depending on the class of the lever.
<span>The question is asking us to define the sentence ""I want to run, to skip, and to jump". This is a parallel construction, which means that the three parts ("to run", "to skip" and "to jump" are in the same kind of construction - to <verb>. It could be considered comma splice, but a comma splice would rather be the case if there were different subjects : for example in "I want to run, she wants to skip". </span>
Answer:
16
Explanation:
The atomic mass of an element is defined as the average of the isotopic masses, weighted according to the naturally occurring abundances of the isotopes of the element. Although oxygen has nine isotopes with mass numbers ranging from 13 to 21, oxygen-13, oxygen-14 and oxygen-15 are not naturally occurring isotopes. So, we do not need to include them when we calculate the relative atomic mass of oxygen.
