Answer : The work done on the surroundings is, 709.1 Joules.
Explanation :
The formula used for isothermally irreversible expansion is :

where,
w = work done
= external pressure = 1.00 atm
= initial volume of gas = 1.00 L
= final volume of gas = 8.00 L
Now put all the given values in the above formula, we get :



The work done by the system on the surroundings are, 709.1 Joules. In this, the negative sign indicates the work is done by the system on the surroundings.
Therefore, the work done on the surroundings is, 709.1 Joules.
Answer:
A) The atoms of the reactants unbond, rearrange and then rebond to form the products
Explanation:
Using method of elimination:
A) The atoms of the reactants unbond, rearrange and then rebond to form the products
This is the correct option. Chemical reactions involves breaking and forming of new bonds.
B) Some atoms disappear while others multiply to form the products
This option is incorrect. Atoms do not disappear
C) The atoms of the reactants always stay together to form the products
This option is incorrect. The bonds between the atoms in the reactants must first be broken before products can be formed.
D) New atoms are formed which combine to make the products
This option is incorrect. Atoms do not just form out of nowhere.
