Explanation:
Answer:
Cellular respiration depends on the water released during photosynthesis.
Explanation:
The best method for separating two liquids in a mixture is distillation among the choices. Distillation separates liquids in terms of their volatility. Evaporation separates liquid from solid. This also applies for filtration which applies porous media for separation. Sorting is applied for two or more different kinds of solids. Answer is distillation.
Water is made of 2 hydrogen and 1 oxygen atoms. The molecular weight for water should be 1+ 1+ 16= 18. Then the amount of water molecule in 11.4 gram of water should be: 11.4g/18= 0.63 moles.
Since 1 water means 2 hydrogen atoms, then the amount of hydrogen atom should be: 2/1 * 0.63= 1.26 moles of hydrogen
Answer:
a) 0
Explanation:
Each of the small dots surrounding the C1 represents one electron. These are where electrivity comes from. Since there is the same number of electrons in both atoms, the difference is 0 (because 6 electrons-6electrons= 0).
