Answer:
<u>Effect of adding heat to the reactions</u>
1. Shift the Reaction <em><u>backward</u></em> in First graph.
2.Shift the Reaction <em><u>forward</u></em> in second graph.
<u>Other ways to change the rate of a chemical reaction are :</u>
1. Addition of Catalyst
2.Increase in surface area
3. Increase in concentration of reactant.
Explanation:
Graph 1
It shows that the reaction is exothermic in which heat is released.
According to Le-Chatelier's rule : If temperature is increased
(heat is added) in an exothermic reaction , it will shift in backward direction.
Graph 2.
It shows that the reaction is endothermic in which heat is absorbed (taken)
According to Le-Chatelier's rule : If temperature is increased
(heat is added) in an endothermic reaction , it will shift in forward direction.
This is a reaction of combustion of methane
CH₄ + 2O₂ = CO₂ + 2H₂O
k(H₂O)=2
Answer
ice wedging .................
<u>Answer</u>:
A single atom of an isotope does not have a(n) Neutron.
<u>Explanatio</u>n:
The lack of neutrons are found to be in an isotope of hydrogen. It has one proton and one electron. This protium has an active ingredient pantoprazole. It is found to be an elective proton pump inhibitor, helps in lowering the acid concentration in the stomach. Being used in the treatment of acid problems in stomach and intestine.it can be abundantly found in the oceans. Protium lacks neutron in the nucleus. It is one among the stable isotope. It is also called as ordinary hydrogen.
