Answer:
Hydrogen ion [H]
Explanation:
overall reaction of photosynthesis is given in this two steps equation .
Firstly, oxygen in water is oxidized by the light energy:
2H2O → O2 + 4 [H.]
[H.] reduces the carbon in CO2:
4 [H.] + CO2 → (CH2O) + H2O
This reaction occurs together, to yeild overall reaction
CO2 + H2O → (CH2O) +O2
Where [H.], the overall reducing agent
Yeast demonstrates cellular respiration because the glucose in it is converted to ATP and carbon dioxide to make breads.
Answer:
Heating causes fluid to expand in volume by reducing its density.
Explanation:
Answer:
1.25 M
Explanation:
In this case, the solute is C₆H₁₂O₆ and the solvent is H₂O.To find the molarity, you need to (1) convert the mass C₆H₁₂O₆ to moles (via molar mass), then (2) convert grams H₂O to liters H₂O, and then (3) calculate the molarity.
(Step 1)
Molar Mass (C₆H₁₂O₆): 6(12.011 g/mol) + 12(1.008 g/mol) + 6(15.998 g/mol)
Molar Mass (C₆H₁₂O₆): 180.15 g/mol
18.0 g C₆H₁₂O₆ 1 mole
------------------------ x ----------------- = 0.0999 moles C₆H₁₂O₆
180.15 g
(Step 2)
1,000 grams = 1 L
80.0 g H₂O 1 L
-------------------- x ------------------- = 0.0800 L H₂O
1,000 g
(Step 3)
Molarity = moles solute / volume solvent (L)
Molarity = 0.0999 moles / 0.0800 L
Molarity = 1.25 M
