Question

Ca(NO3)2+Na2CO3➡️CaCO3⬇️2NaNO3

Answer 1

Ответ:

Объяснение:

Ca(NO3)2 + Na2CO3 = CaCO3↓ + 2NaNO3

Ca(2+) + 2NO3(-)+ 2Na(+) + CO3(2-) = CaCO3↓ + 2Na(+) + 2NO3(-)

Ca(2+) + CO3(2-) = CaCO3↓

Answer 2

The chemical equation you provided represents a double replacement reaction between calcium nitrate (Ca(NO3)2) and sodium carbonate (Na2CO3), resulting in the formation of calcium carbonate (CaCO3) as a precipitate and sodium nitrate (NaNO3) as a soluble salt. The balanced equation for this reaction is:

Ca(NO3)2 + Na2CO3 -> CaCO3 + 2NaNO3

In this equation, the calcium ions (Ca^2+) from calcium nitrate react with the carbonate ions (CO3^2-) from sodium carbonate. The calcium carbonate formed is insoluble and precipitates out of the solution. Meanwhile, the sodium ions (Na+) and nitrate ions (NO3-) remain in the solution as sodium nitrate, which is soluble and remains dissolved.

This reaction is a classic example of a double replacement or precipitation reaction, where the cations and anions from two compounds switch partners to form new compounds.
