The conversations need to solve this problem:
1 cal = 4.184 joules
1 Kcal= 1000 calories
1 kj= 1000 joules
or a more direct approach---->> 1 Kcal = 4.184 Kjoules
8.4 kcal (1000 calories/ 1 Kcal) x (4.184 joules/ 1 cal) x (1 Kj/ 1000 joules)= 35.1 Kj
or 8.4 kcal (4.184 Kj/ 1 kcal)= 35.1 Kj (same answer)

Procedure
Using the periodic table below identify the elements. The periodic table organizes elements in a way that reflects their number and pattern of electrons. The table places elements into columns—groups—and rows—periods.
An element’s column number gives information about its number of valence electrons and reactivity. In general, the number of valence electrons is the same within a column and increases from left to right within a row. Applies only for groups 1,2, 13-18 (remembering that from 13 to 18 the last number is the valence).

Explanation:
in kc we only consider gases and aquas not solids and liquids
These 2 are techniques whereby an individual tries to analyze and observe additional data points or information that may not be recorded and or obvious. From a graph, usually linear.
Interpolation involves the individual to be aware of the pattern observed or relationship between the 2 variables and tries to obtain a value that is in between 2 recorded or defined data points.
Extrapolation involves the individual to estimate and imagine what the graph would appear as if further data was collected, based on the previous recordings. This can be found out due to the relationship between the 2 variables in the graph.
