(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.
At 12 atm pressure and -40°C, carbon dioxide is in the solid phase according to the phase diagram. This corresponds to the region of the phase diagram where CO2 exists in the solid state at those specific pressure and temperature conditions.
When a lemonade bottle is opened, the pressure inside the bottle decreases, causing the equilibrium between carbon dioxide and dissolved carbon dioxide in solution to shift towards the production of more carbon dioxide bubbles to relieve the pressure. This shift is in accordance with Le Chatelier's Principle, which states that a system will shift its equilibrium position in response to a stress applied to it.
Carbon dioxide can be compressed by increasing the pressure on the gas, typically using a compressor or a pressurized container. As pressure increases, the gas molecules become more closely packed together, leading to a reduction in volume. This compressed form of carbon dioxide is commonly used in fire extinguishers, beverage carbonation, and industrial applications.
The most common colorimetric test for carbon dioxide gas involves using limewater (calcium hydroxide solution). When carbon dioxide is bubbled through limewater, it forms a white precipitate of calcium carbonate, indicating the presence of the gas. Additionally, using a pH indicator paper that changes color in the presence of carbon dioxide can also be a simple test.
Green plants take carbon dioxide from the atmosphere, and using energy from the sun separate the carbon from the oxygen. They release the oxygen to the atmosphere, and use the carbon.

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.
Alveolar carbon dioxide partial pressure can be calculated using the alveolar gas equation: PaCO2 = (Pb-PH2O) * FiCO2 - (PaCO2 / R), where PaCO2 is the alveolar partial pressure of carbon dioxide, Pb is barometric pressure, PH2O is water vapor pressure, FiCO2 is inspired fraction of CO2, and R is the respiratory quotient. This equation helps estimate the partial pressure of CO2 in the alveoli.

Very simple: to detect carbon dioxide and to avoid accidents.
Fermentation produces alcohol and carbon dioxide. Burning the alcohol produces more carbon dioxide.
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.
why should uou not touch the horn or pipe when using carbon dioxide extinguisher
To check if there is too much carbon dioxide in a given area because it can kill you
