No. Changing of color is a physical change.
As you move from left to right of the periodic table, the element becomes more negative.
If one wants to make a molar quantity of aluminum oxide from aluminum in the laboratory, the amount of aluminum needed would be 53.96 grams.
<h3>Stoichiometric problem</h3>
Aluminum and oxygen react to form aluminum oxide according to the following equation:
From the balanced equation, the mole ratio of aluminum that reacts to the aluminum oxide that is produced is 2:1.
Now, we want to produce just a molar of aluminum oxide, this means 2 moles of aluminum will be required.
Recall that: mass = mole x molar mass
The molar mass of aluminum is 26.98 g/mol.
Mass of 2 moles aluminum = 2 x 26.98
= 53.96 grams
Thus, the amount of aluminum that one would need to produce a molar aluminum oxide in the laboratory is 53.96 grams.

Pretty sure the answer is A, but you probably shouldn't use Brainly to answer test questions.
God made the earth, I dont know the whole story but in genesis it tells you how the earth was made.
