answer: -
reaction:
na + cl ⇌ nacl
balanced chemical equation:
na + 2cl ⇌ nacl2
sodium + clorine goes to form sodium chloride (table salt).
the product is nacl2.
and the reactants are na and cl.
(note: if you don’t know what ⇌ means, read below: -
⇌(double head arrow) means reversible reaction).
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
