Radiant Energy is electromagnetic energy that travels in transverse waves. Radiant energy includes visible light, x-rays, gamma rays and radio waves. Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on Earth possible.
<span>Heat travels from the sun by a process called radiation. Radiation is the transfer of heat by electromagnetic waves. When infrared rays strike a material, the molecules in that material move faster. In addition to the sun, light bulbs, irons, and toasters radiate heat. When we feel heat around these items, however, we are feeling convection heat (warmed air molecules) rather than radiated heat since the heat waves strike and energize surrounding air molecules. </span>
<span>A light bulb changes the chemical energy of the bulb into electromagnetic radiation, or light. Which in return gets transformed into heat (have you ever touched a light bulb? ouch!). </span>
When you heat up coffee in a microwave, you are transforming electromagnetic energy into heat.http://www.svsu.edu/mathsci-center/uploa...
<span>People have started to utilize electromagnetic energy in the form of solar power, using solar panels to gather the radiant energy that comes from the sun and use it for electricity. For example, a pool that has solar heating panels. </span>

4.67 × 10²⁴ moles
[This is done so the equation is balanced and the reaction can occur]
[subscripts are the number of atoms, and the coefficients are the number of molecules]
______________
Since there are about 6.02 × 10²³ moles in one mol of a substance.
4.67 × 10²⁴ / 6.02 × 10²³ =
7.7547174437 mol.
Next, we must determine the grams per mole of each substance, this can be done with the periodic table.
Since hydrogen, and oxygen gas are diatomic, they will consist of two atoms each. So the atomic mass will be multiplied by 2 to get the molecular mass. Therefore H₂ will have a molecular mass of 1.00794 × 2 = 2.01588 g/mol.
