The product of a reaction between these two elements is .
Explanation:
The oxidation state of an ion in a compound is equal to its charge.
The aluminum having a charge of +3 because oxidation state is +3
The oxide is having charge of -2
The product of these reactants will produce a chemical compound.
The compound formed is i.e Aluminium oxide. The compound while getting formed will share the charge and cation A+ will have the charge of anion and anion will have the charge of cation. This will result in a compound as there should be a neutral charge on the compound formed.
The <em>+</em><em>3 charge of the cation Al+ will go to anion oxide O2- and the charge of anion -2 will go with cation Al+. </em>

Yes, granite is a compound.
Answer:
3.42×10²¹ of particles
Explanation:
To determine the number of particles we should know, that:
1 mol of anything contains 6.02×10²³ particles
Therefore we have to find out, how many moles corresponds to 0.332 g of NaCl.
The conversion is: 0.332 g / 58.44 g/mol = 0.00568 moles
The rule of three to determine the number of particles is:
1 mol of NaCl has 6.02×10²³ particles
0.00568 moles must have (0.00568 . 6.02×10²³ particles )/1 = 3.42×10²¹
Answer: made up of an infinite number of indestructible atoms in unpredictable motion.
