Plastics are ____________________ reactive to chemicals.

Rasek [7]

Answer:

Plastic are non reactive to chemical.

Explanation:

Most plastic is chemically inert and will not react chemically with other substances -- you can store alcohol, soap, water, acid or gasoline in a plastic container without dissolving the container itself. ... Because plastic doesn't react chemically with most other substances, it doesn't decay.

Consider the following intermediate chemical equations.

vichka [17]

Answer:

$Overall\text{ }enthalpy=-1,300kJ$

Explanation:

According to Hess’s law, you can calculate the enthalpy of the overall chemical reaction by adding enthalpy changes of the intermediate reactions, at the same temperature.

First, you must find how the intermediate equations form the overall equation.

Here, the overall equation is:

$P_4O_{6}(s)+2O_2(g)\rightarrow P_4O_{10}(s)$

To obtain it you can swift both the first and second intermediate equations and sum them. When you swift a chemcial equation, the corresponding enthalpy change has the opposite sign:

Change

$P_4(s)+3O_2(g)\rightarrow P_4O_6(s)$ $\Delta H_1=-1,640kJ$
