Answer:
18 atoms has a mass of 18.0g (grams)
65ml x 1.3 molar = 0.0845 moles solution #1
0.0845 moles / .208 L = 0.4 M
0.4M × 104 ml / 213 ml = .20 M after sig figs
The following exist:
Artificial photosynthesis: Plants can photosynthesize, but we can do it artificially to power anything requiring energy.
Solar thermal energy or STE is a process where the light is reflected from a mirror or lense to heat up anything.
Photovoltaics or Heat collectors (Solar panels): they absorb the sun's electromagnetic energy and converts it into electricity.
All of these technologies are very similar to each other... this was a good question
Answer:
No. of Photons (red) = 7.05 No. of Photons
No. of Photons (blue) = 4.78 No. of Photons
Explanation:
v (red) = 3 x 108/700 x 10-9 = 4.28 x 10 power 15 Hz
v (blue) = 3 x 108/475 x 10-9 = 6.31 x 10 power 15 Hz
(a) No. of Photons (red) = E/hv = 2.0 x 10 power -17 / 6.626 x 10 power -34 x 4.28 x 10 power 15
No. of Photons (red) = 7.05 No. of Photons
(b) No. of Photons (blue) = E/hv = 2.0 x 10 power -17 / 6.626 x 10 power -34 x 6.31 x 10 power 15
No. of Photons (blue) = 4.78 No. of Photons
Answer:
0.00050553
