What makes balancing redox reactions different from balancing other reactions?

A. Both the number of atoms and the amount of charge must be

balanced.

B. Redox reactions always occur in a basic solution of OH ions.

ChThe balanced equations have electrons left over as a reactant or

"product.

D. The reactions have to be broken up into half-reactions to balance.

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

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
