Answer:
A; deciduous
Explanation:
Trees that lose all of their leaves for part of the year are known as deciduous trees. Those that don't are called evergreen trees. Common deciduous trees in the Northern Hemisphere include several species of ash, aspen, beech, birch, cherry, elm, hickory, hornbeam, maple, oak, poplar and willow
Lowering the temperature could also be used to decrease the number of collisions that would occur and lowering the temperature would also reduce the kinetic energy available for activation energy. If the particles have insufficient activation energy, the collisions will result in rebound rather than reaction.5
Answer:
The molecular weight (molar mass) of any gas is the mass of one particle of that gas multiplied by Avogadro's number (6.02 x 1023).
Explanation:
How do you find the molar mass of a gas?
First the ideal gas law will be used to solve for the moles of unknown gas (n). Then the mass of the gas divided by the moles will give the molar mass.
<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:
They both alter the pH of a solution.
Explanation:
If a strong acid is added, the pH of a solution will lower. This is because more hydrogens/hydroniums are increasing in the solution. If a strong base is added, the pH will increase. This is because hydrogens/hydroniums are decreasing in the solution.
