I need help if anyone will help plz
maksim [4K]

Answer:

D

Explanation:

If you look at the problem, and the coefficients (the little numbers on the bottom) you will see that on the reactant side you get a total of 11, you look over to the product side and you also get a total of 11.

B. is wrong because they’re are the same amounts

C.is wrong because they have the same amount of carbon

D. Now similar to B but slightly different the matter is the reactant side I’m pretty sure is equal to the amount on the product side.

If I had to take a strong guess though I would choose D just because the question is asking for the one that shows The law of conservation of mass. Pls make me brainlist

CuSO4(aq)

Explanation:

The aqueous for of CuSO₄ is an electrolyte and it will conduct electricity.

CuSO₄ is an ionic substance and in solid state, it will not have the ability to conduct electricity.

  • In aqueous form, it will contain free mobile ions which serves as carriers of electric current.
  • In the solid state, the ions are arranged into a crystal lattice and will not conduct a current of electricity.
  • The remaining given compounds will not conduct electricity as they are non-polar and do not have free mobile electrons.
