Classify the following as Arrhenius, Brønsted-Lowry, or Lewis acid-base reactions. A reaction may fit all, two, one, or none of the categories: (1) Ag + + 2NH3 LaTeX: \leftrightarrow↔Ag(NH3)2+ (2) H2SO4 + NH3 LaTeX: \leftrightarrow↔HSO42-+ NH4+ (3) 2HCl LaTeX: \leftrightarrow↔H2 + Cl2 (4) AlCl3 + Cl- LaTeX: \leftrightarrow↔AlCl4- A. Arrhenius acid-base reactions B. Brønsted-Lowry acid-base reactions C. Lewis acid-base reactions

Explanation:

An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H+). In other words, an acid increases the concentration of H+ ions in an aqueous solution.

An acid-base reaction according to the Brønsted-Lowry definition is a transfer of a proton from one molecule or ion to another. Bronsted-Lowery definition refers to the loss or gain of an H+ (proton). The acid is a proton donor, and the base is a proton acceptor.

A Lewis acid-base reaction is a chemical reaction that forms at least one covalent bond between an electron pair donor (Lewis base) and an electron pair acceptor (Lewis acid). Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons.

1. Ag+ + 2NH3 ⇌ Ag(NH3)2 -

C

2. H2SO4 + NH3 ⇌ HSO4- + NH4+

A, B

3. 2HCl ⇌ H2 + Cl2

None

4. AlCl3 + Cl- ⇌ AlCl4-

C

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

i believe the answer is true.
