Elden [556K]

Answer:

When copper(II) chloride and sodium carbonate solutions are combined, solid copper(II) carbonate precipitates, leaving a solution of sodium chloride. Write the conventional equation, total ionic equation, and net ionic equation for this reaction.

Explanation:

The word equation for the reaction is:

Copper (II) chloride(aq) + sodium carbonate (aq) ->sodium chloride (aq) + copper carbonate(s)

The balanced chemical equation of the reaction is:

$CuCl_2(aq)+Na_2CO_3(aq)->2NaCl(aq)+CuCO_3(s)$

The complete ionic equation is:

$Cu^2+(aq)+2Cl^-(aq)+2Na^+(aq)+CO_3^2^-(aq)->2Cl^-(aq)+2Na^+(aq)+CuCO_3(s)\\$

The net ionic equation is obtained from the complete ionic equation after removing the spectator ions:

$Cu^2^+(aq)+CO_3^2^-(aq)->CuCO_3(s)$

What's a vacuum exactly

stealth61 [152]

Answer:

Vacuum: space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there It is a condition well below normal atmospheric pressure and is measured in units of pressure (the pascal).-the internet gave me this answer so..

hope this helps :)
