What is the bronsted acid of NO2- + H2O HNO2 + OH-​
sammy [17]
<h3><u>Answer</u>;</h3>

H2O -Bronsted Acid

<h3><u>Explanation;</u></h3>
  • Bronsted-Lowry acids are  H+ donors , while Bronsted-Lowry bases are H+ acceptors .
  • A reaction of a Bronsted-Lowry acid and a Bronsted base is a neutralization reaction that is characterized by H+ transfer.
  • The above reaction is an example of base ionization or dissociation where;

                 B (aq) + H2O (l) → BH+ (aq) + OH– (aq)

          That is; Base + Acid will give a conjugate acid + hydroxide ion

  • In our case; NO2- + H2O → HNO2 + OH-​ ; H2O is the H+ donor and thus, it is a Bronsted Acid.

If i initially have 4.0 l of a gas at a pressure of 1.1 atm, what will the volume be if i increase the pressure of 3.4 atm?
ddd [48]
  The  volume  of  a  gas  that   its  pressure  increase  to  3.4  atm   is    calculated  as   follows

  By  use  of  boyles   law   that  is  P1V1=P2V2
V1=4.0  L
P1=1.1  atm
P2=3.4  atm
V2= P1V1/P2  

(1.1  atm  x  4.0 L)/3.4  atm=  1.29  L
