Evgen [1.6K]3 years ago

Answer:

The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.

Amines are ________. brønsted-lowry bases brønsted-lowry acids neutral in water solution unreactive
sammy [17]

Answer:

A.) Brønsted-Lowry bases

Explanation:

Amines have a lone pair of electrons.

Brønsted-Lowry bases donate a lone pair of electrons in exchange for a hydrogen ion.

Therefore, if exposed to an acid, amines will give up electrons in order to bond with a hydrogen. This makes them Brønsted-Lowry bases.

A gas has a volume of 10.0 liters at 373K and a pressure of 5.0atm, what volume will the gas occupy at STP?
zhannawk [14.2K]
Use ideal gas law PV=nRT
Convert 5.00 atm to kPa since units must be relative to gas constant (r).
To do this multiply 5 by 101.03 (1 atm=101.3kPa)
Now plug in (506.5kPa)(10.0L)=n(8.31 L•atm/mol•K)(373K)
Solve for n (moles) to get approximately 1.634 mol. Now use dimensional analysis (1.634mol/1)(22.4L/1mol) = 36.6L

what is the difference between the number of electrons in an atom of selenium and the number of electrons in an atom of aluminum
igomit [66]

Answer:

The atomic number of Selenium is 34. This means that Selenium possesses 34 electrons.

The atomic number of Aluminium is 13. This means that Aluminium has 13 electrons.

Hence, there is a difference of 21 between the number of electrons in an atom of selenium and the number of electrons in an atom of aluminium.

Selenium has 6 electrons in it's outer most shell whereas aluminium has 3 electrons in its outer most shell. As a result, aluminium will have a greater tendency to lose one of its outer most electrons to become stable.
