When baking soda (NaHCO3) and vinegar (HC2H3O2) react, one of the products is carbonic acid (H2CO3). Carbonic acid rapidly decomposes into carbon dioxide gas (CO2) and water (H2O), which are two of the compounds found in volcanic gas. In this experiment, you’ll measure how these gases alter temperature. Before starting the experiment, Explain your reasoning.

please helppp!!!

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.
