A .gamma
Because composed of photons, which have neither mass nor electric charge and, as a result, penetrates much further through matter than either alpha or beta radiation.
Answer:
From this I could observe the effect of concentration and surface area on the reaction rate. The concentrated acids can dissolve a large piece of limestone in a few days because the higher reactant concentration leads to more frequent collisions which increases the reaction rate. Acid rain is diluted with water which is why it can take decades. However, statues with intricate carvings break down more quickly because it increases the surface area which increases reaction rate.
Explanation:
We call these reactive elements, becausethese atoms really like to follow the buddysystem and form bonds with other atoms.Noble gases, however, don't have thisproblem. Their outer shells are filled to the max, so they don't need to bond or react with any other atoms.
The right answer is C.
Oxidation is the loss of electrons. A loss of electrons will appear as an increase in the positive charge of the element as it is converted to an ion. Here we have aluminum have an oxidation state equals zero as a reactant because it is in the element state. After reacting, it combines with three atoms chlorine where each chlorine atom usually has an oxidation state equals -1, therefore, we have -3 charges which have to be neutralized with the 3+ charges of aluminum.
