The solubility of a gas in a liquid increases with increasing pressure. To understand the above statement, consider a familiar e
xample: cola. In cola and other soft drinks, carbon dioxide gas remains dissolved in solution as long as the can or bottle remains pressurized. As soon as the lid is opened and pressure is released, the CO2 gas is much less soluble and escapes into the air. The relationship between pressure and the solubility of a gas is expressed by Henry's law: S=kP, where S is concentration in M, k is the Henry's law constant in units of mol/(L⋅atm), and P is the pressure in atm. Note: Since temperature also affects the solubility of a gas in an liquid, the Henry's law constant is specific to a particular gas at a particular temperature. The following table provides some information on carbon dioxide solubility in water. S (mol/L) P (atm) k (mol⋅L−1⋅atm−1) T (∘C) 3.80×10−2 1.00 20.0 6.60×10−2 20.0 1.00 3.50×10−2 25.0 Part A What is the Henry's law constant for CO2 at 20∘C?
Creativity is often defined as the ability to generate innovative ideas and manifest them from thought into reality. Any science experiment that is being done for the first time is creative because it's an innovative idea that's being transformed into reality by creating/doing the experiment.
The answer is D. If you've ever had table salt before you know it's not poisonous or nearly as reactive as sodium. When the two combine, they produce a new pure substance with different properties from the original reactants.
