<u>Answer:</u>
<u>For (i):</u> Magnesium is getting oxidized and zinc is getting reduced.
<u>For (ii):</u> The half reactions are given below.
<u>For (iii):</u> Magnesium will act as anode and zinc act as cathode.
<u>Explanation:</u>
The substance having highest positive potential will always get reduced and will undergo reduction reaction. Here, zinc will always undergo reduction reaction will get reduced.
Magnesium will undergo oxidation reaction and will get oxidized.
Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
Oxidation half reaction:
Reduction half reaction:
Oxidation reaction always occurs on anode side and thus, magnesium is acting as anode.
Reduction reaction always occurs on cathode side and thus, zinc is acting as cathode.
Answer:
A pure substance is a substance composed of one substance. It has fixed physical and chemical properties. It has special chemical symbols, which can be expressed by a chemical formula. Water is pure, so what you mean by liquid ice is pure.
Explanation:
Answer:
12 grams
Explanation:
the mass of 1 mole of carbon is equal to the number of atoms in 12 grams of carbon-12; this number is referred to as Avogadro's number and has been measured as approximately 6.022 x 1023.
Answer:
True
Explanation:
The moon exhibits synchronous rotation. This means that the time taken to go around its center is equal to the time taken to go around its orbit. Therefore, one rotation is of the moon is approximately equal to its one revolution.
Answer: <span>The actual yield depends on the reaction conditions, but the theoretical yield varies only with reactant amounts.
The actual yield has to be detemined from the real data.
The theoretical yield is calculated with the reactants amoounts and the theroretical molar ratios indicated by the chemical equation. Thus, the theoretical yield is the maximum possible yield, from the total reaction of the limiting reactant. The actual yield must be detemined under the particular contitions on which the reaction is performed.
