A tend line I believe (I am going off the other guy cause they are right.)
The chemical reaction is written as:
2Zn + O2 = 2ZnO
We are given the amount of the product to be produced from the reaction. We use this value and the relation of the substances in the reaction to calculate what is asked. We do as follows:
2.10 g ZnO ( 1 mol / 81.408 g ) ( 1 mol O2 / 2 mol ZnO ) ( 32 g / 1 mol ) = 0.414 g O2 is needed
Tsunamis are the largest waves in the world. The edges of the plates, where earthquakes and volcanoes often occur, usually lie near the edges of the oceans
Answer:
The Answer should be Endothermic reaction
Explanation:
Reactions in which energy is absorbed are called Endothermic reactions.
The answer should be A.
Hope this helps :-)
