4 Al + 3 O2 --> 2 Al2O3
SIZIF [17.4K]

Answer:

The answer to your question is 7.4 moles of Aluminum

Explanation:

Data

moles of Al = ?

moles of Al₂O₃ = 3.7

Balanced chemical reaction

                4 Al  +  3 O₂  ⇒  2 Al₂O₃

To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced chemical equation.

                4 moles of Aluminum ----------------- 2 moles of Al₂O₃

                 x                                  ----------------- 3.7 moles of Al₂O₃

                            x = (3.7 x 4) / 2

                            x = 14.8 / 2

                            x = 7.4 moles of Aluminum

Which statement describes the distribution of charge in an atom?
miv72 [106K]

The correct answer is:

A positively charged nucleus is surrounded by one or more negatively charged electrons

The explanation:

when:

proton is a positively charged elementary particle that is a fundamental constituent of all atomic nuclei.

neutron is a subatomic particle found in the nucleus of every atom except that of simple hydrogen. The particle derives its name from the fact that it has no electrical charge

electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom .  

so, , there are positively charged protons and zero-charged neutrons in the nucleus of an atom. Therefore, the nucleus is positively charged, Surrounding the nucleus, the electrons have negative charge. 

Thus, the correct answer is (3): A positively charged nucleus is surrounded by one or more negatively charged electrons is correct.
