I'm pretty sure your answer should be CaCl2. Hope this helps! =^-^= (if I need to explain more just let me know.)
Answer :
Standard enthalpy of formation : It is defined as the enthalpy change for the reaction that forms one mole of compound from its elements. All the substances in their standard states.
The balanced chemical equation for the reaction is,
In the balance reaction, Strontium (Sr), Carbon (C) and Strontium carbonate are in solid state and oxygen is in gaseous state.
the scientific method allows to find the answers
1) it is not correct to show unmeasured points
2) extend the experiment or graphs without missing points
3) make the graphs without the missing points and analyze the curves
the scientific method is a set of rules and processes to ensure that an investigation is correct and is not influenced by the prejudices of the researcher
1) Science is based on experimental facts, with these facts it performs, tables, graphs, it postulates principles and laws, therefore it is not correct to include values that have not been measured experimentally.
2) In this experiment there are several observations
- Make the graph without these points, which are very few, has 34 experimental points and only 6 missing, this represents a small fraction
% missing =
% missing = 15%
- Extend the study one more month to have more points and that the fraction of missing points decreases
3) If the researcher had presented the graph without the missing points, the sample that he has must already show the trend of the movement of the sun with respect to the days, making curves that fit the data.
In conclusion using the scientific method allows to find the answers
1) it is unethical to show unmeasured points
2) extend the experiment
3) make the graphs without the missing points and analyze the curves

If the fossils from one shore are also on a different shore on a different continent, they probably didn't migrate from shore to shore. sorry that I didn't shorten it as much as I could.
