N₂
Explanation:
The molecule with the shortest bond length is nitrogen gas N₂ because it has a triple bond between the covalently bonded atom.
- Molecules with more number of bonds are usually stronger.
- The bond length is the average distance between two nuclei that are bonded in a molecule.
- Single bonds are usually very long and relatively weaker in nature. They easily broken and forms between atoms that are large in size because their nuclei is far from each other.
- Double bonds are stronger than single bonds and longer in nature.
- Triple bonds such as seen in Nitrogen gas are very strong bond types. They are the shortest.

Answer : 'Fe' is oxidized reactant and 'Cu' is reduced reactant.
Explanation :
Redox reaction or Oxidation-reduction reaction : It is defined as the reaction in which the oxidation and reduction reaction takes place simultaneously.
Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. In this, oxidation state of an element increases. Or we can say that in oxidation, the loss of electrons takes place.
Reduction reaction : It is defined as the reaction in which a substance gains electrons. In this, oxidation state of an element decreases. Or we can say that in reduction, the gain of electrons takes place.
The balanced redox reaction will be:
In this reaction, the oxidation state of 'Fe' changes from (0) to (+3) that means 'Fe' lost 3 electron and it shows oxidation reaction and the oxidation state of 'Cu' changes from (+2) to (0) that means 'Cu' gain 2 electron and it shows reduction reaction.
Thus, 'Fe' is oxidized and 'Cu' is reduced.
Na3PO4*12H2O + BaCl2*2H2O = Ba3(PO4)2 + NaCl + H2O
add barium chloride to your Na3PO4.12H2O a white precipitate of Ba3(PO4)2 will be formed wrt salt(NaCl) and water(H20) if Na3PO4.12H2O. will be there.
<h3><u>
Answer:</u></h3>
The reaction would progress faster and the activation energy would be lowered when the enzyme gets added.
<h3><u>
Explanation:</u></h3>
Enzymes are proteins that basically speed up the chemical reaction without being used. Enzymes are usually specific for a particular substrate. The substrate in the reaction bind to the active site of the enzyme which is present on the surface of the enzymes forming the enzyme-substrate complex.
Performing the enzyme-substrate complex the enzyme changes the shape slightly so that the substrate can fit tightly to its active site. Then this enzyme-substrate Complex undergoes a reaction to form a product. Enzymes lower the activation energy of a reaction i.e the required amount of energy needed for a reaction to occur.They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently.
