Both involve chemical bonds breaking
Answer:
B. (Linear graph with positive slope)
Explanation:
The picture above showing that
1. T2 is higher than T1
2. V2 is higher than V2
From this, we can conclude that the relationship for temperature (T) and volume(V) is positive. That means a higher temperature will result in a higher volume.
Since the relationship positive, the graph will have a positive slope. We can't prove if the graph should be linear or exponential since we don't have the exact number of the experiment.
Answer: mass and relative abundance of each isotope of that element
Explanation:-
For example:
If an element X has two isotopes with following masses ad abundance:
Mass of isotope 1 = 267.8 amu
% abundance of isotope 1 = 87.8% = 0.878
Mass of isotope 2 = 269.9 amu
% abundance of isotope 2 = 12.2% = 0.122
Formula used for average atomic mass of an element :
Answer:
Atomic number : 15 mass number: 32+15=47
47
electrons : 15 complete symbol : 15 P
