liquid
(Explanation): If you look at the phase diagram for CO2, and you draw a lines where the temperature and pressure meet, you will see that the point will be inside the zone that is 'solid', so it is in the solid state.
because the bubbles of carbon dioxide have a smaller density so they rise and float on top of the lemonade

solid, I just took the text on apex

Carbon dioxide is forced into the liquid at high pressure, causing some of it to dissolve (actually, even at normal pressures some carbon dioxide will dissolve in water, but using higher pressure makes more of it dissolve).
The triple point of Carbon Dioxide is 216.55 K (−56.60 °C) and 517 kPa (5.10 atm). Since that puts the pressure (1 atm) below the triple point pressure (5.1 atm) we are only concerned with the where the solid/vapor equilibrium line falls relative to the temperature. At 1 atm, the sublimation temperature of Carbon Dioxide is -78.5 °C - considerably below -20 °C so that puts the Carbon Dioxide firmly in the vapor region of the phase diagram.

Very simple: to detect carbon dioxide and to avoid accidents.

Well I use carbon dioxide in my fire extinguisher. What do you use carbon dioxide, or to put it another way? In what do you use carbon dioxide? Humans breathe out carbon dioxide... Breathing it out is not exactly using it. That would be more like making it.
To determine the volume of carbon dioxide needed, you would need to know the stoichiometry of the reaction between carbon dioxide and calcium carbonate. In this case, since 20 grams of calcium carbonate is given, you would convert that to moles using the molar mass of calcium carbonate. Then, using the balanced equation, you can determine the mole ratio between carbon dioxide and calcium carbonate. Finally, using the molar volume of carbon dioxide gas at the given conditions (usually 22.4 L/mol at standard temperature and pressure), you can calculate the volume of carbon dioxide needed.
Fermentation produces alcohol and carbon dioxide. Burning the alcohol produces more carbon dioxide.
Yes
why should uou not touch the horn or pipe when using carbon dioxide extinguisher
