Answer:
The answer to your question is False.
Explanation:
Data
1 mole of NH₄NO₃
0.75 moles of N₂O
Percent yield = 25%
Chemical reaction
NH₄NO₃ ⇒ N₂O + 2H₂O
Process
1.- Determine the theoretical yield
1 mol NH₄NO₃ ------------- 1 mol of N₂O
2.- Calculate the percent yield
Percent yield = Actual yield / Theoretical yield x 100
-Substitution
Percent yield = 0.75 / 1 x 100
-Simplification
Percent yield = 0.75 x 100
-Result
Percent yield = 75%
Conclusion
False, the actual percent yield is 75%
Salted butter does not need to be stored in the fridge since the risk of bacterial growth is so low. ... However, it will stay fresh longer if it is kept in the refrigerator. Refrigeration slows down the process of oxidation, which will eventually cause butter to go rancid.
I hope this helps!
Answer:
C) P3– > Cl– > K+ > Ca2+
Explanation:
Ionic radius can be defined as the distance between the nucleus and the electron in the outermost shell of atom in its ionic state. When an atom looses an electrons(Cation) its ionic radius decreases, whereas when an atom gains an electron(anion), its ionic radius increases.
Among the given ions the ionic radius of
all distances are in picometer.
clearly,
option C is correct that is
C) P3– > Cl– > K+ > Ca2+

Good luck!
Answer: IN terms of the collision theory, increasing the concentration of a reactant increases in the number of collisions between the reacting species per second and therefore increases the reaction rate.
