Need it fast!! Given the balanced equation below, calculate the moles of aluminum that are needed to react completely with 13.2
satela [25.4K]
By looking closely into the given balanced chemical reaction, it can be deduced that the number of moles needed for every mole of FeO is only 2/3. Calculating for the number of moles of aluminum,

                      x = (13.2 moles FeO)(2 mols Al/3 moles FeO)
 
                       x = 8.8 moles Al

Answer: 8.8 moles Al

One radioactive isotope of calcium has an atomic mass of 47,how many neutrons are in the calcium -47 nucleus
jekas [21]

Answer: 27 neutrons

Explanation:

Recall that the number of protons in the nucleus of an atom = Atomic number.

Hence, Calcium with mass number 47 and atomic number 20 will have 20 protons

Therefore, since Mass number = number of protons + neutrons

47 = 20 + neutrons

Neutrons = 47 - 20 = 27

Thus, there are 27 neutrons in radioactive calcium nucleus.

Explanation:

An anion is a charged particle with a negative charge. Anions has charge of -1

Oxygen require two electrons to complete its octet and hence its charge is -2

Calcium is  a cation and has a positive charge of +2
