Answer and Explanation:
Isotopes are same in atomic number and different in atomic mass. Isotopes have same number of electron and proton but different number of neutron and due to same proton their atomic numbers are same and due to different number of neutron their atomic mass are different because neutron also take part in atomic mass
Enzymes are catalysts in chemical reactions.
Answer:
It will be an unstable system because it will not be able to recover from the disturbance.

Answer:
Mg + AgNO₃ → Ag + Mg(NO₃)₂
Explanation:
A single replacement reaction is one in which an element gets replaced by another in a compound.
In the reaction
Mg + AgC→ Ag + Mg(NO₃)₂
Ag in AgNO₃ is replaced by Mg to give Mg(NO₃)₂.Only one element is getting replaced and hence it is a single replacement reaction.
<span>You must balance your equation correctly.
Here is your answer:
294gFeS2 x 1molFeS2/119.99 x 11mols O2/4mols FeS2--> 6.738mol O2
176gO2 x 1mol O2/32gO2 x 4mols FeS2/11mol FeS2--> 2mols FeS2
Now choose the molecule with the lowest amount (Limiting Reagent)
2molsFeS2 x 2molsFe2O3/4molsFeS2 x 159.7g
159.7g Fe2O3 grams produced.</span>
