The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: The equation was CaCO3 →CaO+CO2
He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer. Draw a model showing the number of each type of atom in the reactants and products. Use your model to explain your answer.

PLEASE HELP

Describe the relationship between wavelength and the energy of the wave.

Answers

Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
