An air conditioning condenser contains pure CClF3. If a condenser has a volume of 2.0 L at room temperature, how many moles of gas CClF3 will be in the condenser if the condenser is unpressurized and at atmospheric pressure (1 atm) and room temperature (25 degrees C)?

Which real-world scenarios below represent physical and chemical changes? -running a car -exploding fireworks -mixing water and powdered drink mix -combining oil and vinegar to make salad dressing -taking aspirin for a headache -diluting bleach with water-digesting dinner-spreading peanut butter on bread

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
