Hope this helps
Answer:
The correct answer based on the criterion of whether the temperature increases or decreases.
Explanation:
If the ambient temperature increases when a reaction takes place, we can deduce that it is an exothermic reaction, since in this type of reaction the system gives heat to the environment, increasing the temperature.
On the other hand, if the ambient temperature decreases, we can deduce that we are in front of an endothermic reaction, since in this type of reaction the system absorbs heat from the environment so the temperature decreases.
Have a nice day!
Answer:
0.185moles
Explanation:
1mole of bicarbonate produces 1mole of CO2
so 0.185 mole produces 0.185 moles of CO2
tree rings
Explanation:
A dendrochronologist interprets tree rings to ascertain the age of a particular tree.
Dendrochronology is a a scientific process that involves the dating of tree rings to determine the age of a particular tree.
- It is sometimes called tree-ring dating.
- This method of dating is mostly applicable to woody trees that have large years of growth.
- New rings develops in order to accommodate new structural materials like the secondary xylem and phloem in them.
- The nature of this secondary growth pattern can be used to systematically determine how old a particular tree is.
