This is a really hard one just tell your teacher its not like she/he will get mad for not doing one question and think you will get it
Answer:
2RbNO₃ + BeF₂ → Be(NO₃)₂ + 2RbF, because Be keeps a 2+ charge throughout the reaction.
Explanation:
- It is a double replacement reaction.
- A double replacement reaction is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
- In this reaction, there is no change in the oxidation state of different atoms.
- It is just a replacement reaction.

For all of Carbon's valencies to be satisfied:
H₂C = C = CH₂
Thus, the answer is:
B) Two
I’m not 100% sure but I think it’s C
