<u>Answer:</u>
NO ---> N +2 and O -2
<u>Explanation:</u>
Oxidation numbers are assigned to the elements of a compound to keep a track of the number of electrons each atom has.
Here we have a compound NO (Nitrogen Oxide). The Nitrogen is assigned an oxidation number of +2 while Oxygen in this compound is assigned an oxidation number of -2.
So the algebraic sum of the oxidation numbers of the elements in the compound NO is equal to zero.
To be honest the answer should be B. Hope this help.
Answer:
=1.4953 moles
Explanation:
Iron (III) Oxide is reduced by carbon (II) oxide into Iron. According to the following equation, One mole of Fe₂O₃ react with 3 moles of CO to produce 2 moles of Fe. Thus the reaction ratio of CO to Fe₂O₃ is 3:1
Fe₂O₃₍s₎ + 3CO → 2Fe₍s₎ + 3CO₂₍g₎
125.6 grams of CO is equivalent to: 125.6g/28.0g/mol
=4.486 moles.
The number of moles of Fe produced by the reaction is:
=(4.486 moles×1)/3
=1.4953 moles
The model of photosynthesis used by biologists begins when chlorophyll splits a water molecule into hydrogen and oxygen. The oxygen from the water is a waste product that is released as a gas. In later stages of photosynthesis, carbon dioxide from the air and hydrogen from the water unite to form glucose. Photosynthesis usually takes place in the leaves of green plants. The food produced is a simple sugar called glucose. Some of the food made during photosynthesis is used by plants for their growth and development. The rest is stored in the plant.
Answer:
E°= E°cathode- E° anode= 0.271-0.330= -0.59V
Explanation:
NB: the stoichiometry does not affect E°values,
And the more positive the E° values , the greater it's tendency to become spontaneous and hence irreversible, and the more negative the E° values the more likely to become less spontaneous and reversible, hence the above reaction is reversible
