Answer:
7.98 g of glucose are needed to prepare 399 mL of glucose solution
Explanation:
2.0 % m/v
This data represents, a sort of concentration for solutions.
It means that, our solution contains 2 g of solute, in this case glucose, which are contained by 100 mL of solution.
We only have to make a rule of three, in order to solve the question:
In 100 mL of glucose solution, we have 2 g of solute
In 399 mL of glucose solution, we may have:
(399 . 2) / 100 = 7.98 g
Answer:
Explanation:
An oxidizing accepts an electron and becomes reduced while a reducing agent loses an electron and become oxidized.
Chemical equation:
1) 2 N₂H₄ + N₂O₄ → 3 N₂ + 4 H₂O
2) Hydrazine ( N₂H₄) is being oxidized
Dinitrogen tetroxide N₂O₄ is being reduced
3) The reducing agent is Hydrazine ( N₂H₄) and the oxidizing agent is dinitrogen tetroxide (N₂O₄)
Answer:
True. Hope this helps. :)
