A "fizz saver" pumps air under pressure into a soda bottle to keep gas from escaping. will this keep co2 in the soda bottle? exp

timofeeve [1]

<span>A fizz saver forms an airtight seal around the now-upsidedown soda bottle, and the pressure exerted by the drink and the atmospere outside pushes out the drink through the slightly-elevated spout. The CO2 gas does not fizz out because it stays at the bottom of the upside-down bottle. Thus the CO2 gas is trapped and the drink is carbonated at a longer time.</span>

Answer:

See explanation.

Explanation:

Hello!

In this case, since the main molecular reaction that is taken place in the beaker is:

$AgNO_3(aq)+BaI_2(aq)\rightarrow AgI(s)+Ba(NO_3)_2(aq)$

In such a way, we understand that one breaker contained silver nitrate and the other one barium iodide. Thus, the complete molecular equations turns out:

$2AgNO_3(aq)+BaI_2(aq)\rightarrow 2AgI(s)+Ba(NO_3)_2(aq)$

Now, for the complete ionic equation, we just ionize the aqueous species:

$2Ag^++2NO_3^-+Ba^{2+}+2I^-\rightarrow 2AgI(s)+Ba^{2+}+2(NO_3)^-$

Finally, for the net ionic equation we cancel out barium and nitrate ions as the spectator one because they are both sides on the equation:

$2Ag^++2I^-\rightarrow 2AgI(s)$

Best regards!
