Which of these are a bronsted acid, a bronsted base or are both the bronsted acid and the bronsted base? 
UNO [17]
We can classify the ion molecules as follows:

PO4^3-  = Bronsted Base
ClO2- = Bronsted Base
NH4+ = Bronsted Acid
HCO3- = Both
H2PO4- = Both

For a Bronsted-Lowry acid and bases, an acid is a proton (hydrogen ion) donor. A base is a proton (hydrogen ion) acceptor. Hope this answers the question. Have a nice day.

The atomic number of nitrogen is 7. How many protons, neutrons, and electrons make up an atom of Nitrogen-15?
earnstyle [38]
<h2><u>Answer:</u></h2>

A nonpartisan iota of Nitrogen has a mass of 18. There are 7 protons in the core of this iota. What number of neutrons, complete electrons, and valence electrons are available  

Nitrogen 15 has a nuclear mass of 15. The mass number is # protons in addition to # of neutrons, so for N-15 mass is 15 and the protons are dependably 7 so there must be 15-7=8 neutrons. N-15 has 7 electrons since it has 7 protons and p = e.

Determine the oxidation state of nitrogen in lino3.
Andre45 [30]

Answer : The oxidation state of nitrogen in LiNO_3 is, (+5)

Explanation :

Rules for the oxidation numbers :

  • The oxidation number of a free element is always be zero.
  • The oxidation number of a monatomic ion equal to the charge of the ion.
  • The oxidation number of  Hydrogen (H)  is +1.
  • The oxidation number of  oxygen (O)  in compounds is usually -2, but it is -1 in the peroxides.
  • The oxidation number of a Group 1 element in a compound is +1.
  • The oxidation number of a Group 2 element in a compound is +2.
  • The oxidation number of a Group 17 element in a binary compound is -1.
  • The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
  • The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.

The given compound is, LiNO_3

Let the oxidation state of 'N' be, 'x'

(+1)+x+3(-2)=0\\\\x=+5

Hence, the oxidation state of N is, (+5)
