Which of these factors make hydrogen fuel cells a better option than burning fossil fuels? hydrogen fuel cells have a higher energy efficiency. hydrogen fuel cells create less pollution. burning fossil fuels relies on outdated devices and technology. pure hydrogen is more readily available than fossil fuels. hydrogen fuel cells are more expensive than fossil fuels.

Schrodinger and heisenberg developed an alternate theory about atomic nature that contradicted some of bohr's model of the atom. how do changes resulting from new technology and evidence affect the reputation of the atomic theory?

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!

Compare and contrast the bohr model and the electron cloud models of the atom.
