A sample of gas occupies 250 mL at STP. What is the temperature if the gas expands to 1500 mL at a pressure of 0.500 atm? *

Much of the general structure and physical properties of the interior of the earth are inferred from: a)deep oil and gas bore holes b)geologic investigations c)analysis of seismic waves d) study of volcanoes

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

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.
