individual isotopes
Re 185 = 139.094
Re 187 = 232.815
Explanation:Correcting the typo error for natural abundance as 37 40 as 37.40 and 62 60 as 62.60
Answer is found as follows
For Re 185 natural abundance 37.40%
371.9087 x 37.40/100 = 139.0938538
six significant figures after rounding off = 139.094
For Re 187 natural abundance 62.60
371.9087 x 62.60/100 = 232.8148462
six significant figures after rounding off = 232.815
This problem can be solved directly using stoichiometry.
We can actually see that for every mol of P4O10, there are 4 moles of P.
Therefore the total moles of P is:
moles P = 88.5 moles P4O10 * (4 moles P / 1 mole P4O10)
<span>moles P = 354 moles P</span>
Its white
It has temperature
It has density and
It has volume! :)
Explanation:
Photosynthesis is the process by which green plants manufacture their food using carbon dioxide and water in the presence of sunlight.
It is expressed using the equation below;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
reactants products
1. Compounds consumed are carbon dioxide and water.
2. Product is glucose and oxygen.
3. Most organism obtain their nourishment directly and indirectly from photosynthetic activities.
Plants are the producers of food in the ecosystem. If the process of photosynthesis does not occur, there is no way other organisms will obtain their own nourishment.
