Some hydrogen fuel cell vehicles fill up at a gas station that uses hydrolysis to produce the hydrogen gas. When hydrogen is combined with oxygen in the fuel cell, energy is released to power the car. The reaction is like hydrolysis in reverse 2H2O (liq.) + energy + 2H2 (gas) + O2 (gas) Pick all statements which are true. Select one or more: O a. hydrogen fuel cells can produce more energy than is used to create the hydrogen by...

Some hydrogen fuel cell vehicles fill up at a gas station that uses hydrolysis to produce the hydrogen gas. When hydrogen is combined with oxygen in the fuel cell, energy is released to power the car. The reaction is like hydrolysis in reverse 2H2O (liq.) + energy ← 2H2 (gas) + O2 (gas) Pick all statements which are true. Select one or more: a. using hydrogen made by electrolysis is more efficient and cleaner than using the fuel or electricity...

Absorption and transmission: When a photon of light hits a molecule of gas or a particle...
Absorption and transmission: When a photon of light hits a molecule of gas or a particle in the atmosphere, there are three possibilities: 1) it can be absorbed (the energy is converted to heat), 2) it can be reflected (it continues on but in a different direction), 3) or it can be transmitted. These processes determine our ability to see distant objects (such as the mountains around Los Angeles and Irvine) and the colors in the sky (such as blue...

Fields on the Page Estimate the maximum magnitudes of the electric and magnetic fields of the light that is incident on a page because of the visible light coming from your desk lamp. Treat the lightbulb as a point source of electromagnetic radiation that is 6% efficient at transforming energy coming in by electrical transmission to energy leaving by visible light. SOLUTION Conceptualize The filament in your lightbulb emits electromagnetic radiation. The brighter the light, the larger the magnitudes of...
