Which are produced when hcl reacts with ca(oh)2?
a) cl2, h3, and cao
b) cacl and h3o cao,
c) cl2, and h2o
d) cacl2 and h2o

The product when HCl reacts with Ca(OH)2 is

CaCl2 and H2O (answer D)

that is Ca(OH)2 + HCl → CaCl2 + H2O

strong Base and strong acid react to form salt and water Ca(OH)2 is a base which react with HCl an acid to form CaCL2 a salt plus water (H2O)

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
