How many kilojoules of heat energy are absorbed by a 200. g block of ice from -10°C to 0°C?​

What forms when chemical reactions combine pollution with sunlight?

Will mark brainliest how many electrons can be held in the energy level n = 4?

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.
