Question

Na2CO3 + ………. → ……… + CO2 + H2O - что вставить в пропуски?

Answer 1

Ответ:

Объяснение:

Na2CO3 + 2HBr = 2NaBr + CO2 + H2O

Answer 2

Na2CO3+HCL=NACL+H20+CO2

Answer 3

The balanced chemical equation for the reaction between sodium carbonate (Na2CO3) and another substance can be determined as follows:

Na2CO3 + X → Y + CO2 + H2O

To complete the equation, we need to identify the missing substances X and Y. Since there are many possible reactions depending on the context, I'll provide two common examples:

Example 1: Reaction with Hydrochloric Acid (HCl)

In this case, when sodium carbonate reacts with hydrochloric acid (HCl), the equation is:

Na2CO3 + 2HCl → 2NaCl + CO2 + H2O

Example 2: Thermal Decomposition

When sodium carbonate undergoes thermal decomposition, the equation is:

Na2CO3 → Na2O + CO2

These are just two examples, and there could be other reactions with different substances depending on the context. Please specify the conditions or provide more information if you are referring to a specific reaction.
