Question

CuCO3 W(C) - ? !!!!!!!!!

Answer 1

Ответ:

Объяснение:

Mr(CuCO3) = 64+12+48=124

Ar(C) =12

W(C) = 12/124 *100% = 9.7%

Answer 2

It seems like you're trying to represent a chemical reaction or formula involving copper carbonate (CuCO3) and tungsten (W), but the notation is not clear. Let me provide you with some information about these substances:

1. Copper Carbonate (CuCO3):

   • Copper carbonate is a chemical compound with the formula CuCO3.
   • It is a greenish-blue solid.
   • Copper carbonate can decompose when heated, forming copper oxide (CuO) and releasing carbon dioxide (CO2).

2. Tungsten (W):

   • Tungsten is a chemical element with the symbol "W" and atomic number 74.
   • It is a dense, metallic element known for its high melting point and hardness.
   • Tungsten is often used in various applications, including in the manufacturing of electrical wires, lightbulb filaments, and as an alloy in steel production.

If you have a specific chemical reaction or question about these substances, please provide more details, and I'll be happy to help clarify or provide information based on your request.
