Answer:
The answer to your question is Single replacement
Explanation:
Types of reaction in Chemistry
Synthesis two or more reactants combine to produce one single product
Decomposition one reactant splits producing two or more products
Single replacement One element replaces a similar one in a compound.
Double replacement Two compounds interchange their cations and anions.
Combustion one compound reacts with oxygen to produce carbon dioxide and water.
Reaction given
Fe⁺² + CuSO₄ ⇒ Cu + FeSO₄
This is a single replacement reaction
Answer:
64J of energy must have been released.
Explanation:
Step 1: Data given
One reactant contains 346 J of chemical energy, the other reactant contains 153 J of chemical energy.
The product contains 435 J of chemical energy.
Step 2:
Since the energy is conserved
Sum of energy of Reactants = Energy of Products
Sum of energy of Reactants = 346 J + 153 J = 499 J
The energy of the product = 435 J
435 < 499
This means energy must have been lost as heat.
Step 3: Calculate heat released
499 J - 435 J = 64 J
64J of energy must have been released.
I really hope i helped you! :)
The reaction that has the greatest tendency to be reversed in an spontaneous redox reaction is that whose forward standard reduction potential is the lowest (mos negative) one because that means that the reversed reaction will have the highest (most positive) standard reduction potential.
So, the answer is Cr(3+) + 3e- ---> Cr(s) with Eo = -0.91 V, whose reversed reaction is Cr(s) - 3e- ---> Cr (3+) with Eo = +0.91 V.
Answer: the second option Cr(3+) + 3e- ---> Cr(s) Eo = -0.91 V
- increasing the concentration of N₂
- increasing the concentration of O₂
- decreasing the concentration of NO
- increasing the temperature
