Using the reaction below: 2 CO2(g) + 2 H2O(l) → C2H4(g) + 3 O2(g) ΔHrxn= +1411.1 kJ What would be the heat of reaction for this

maw [93]

Answer: d) -705.55 kJ

Explanation:

Heat of reaction is the change of enthalpy during a chemical reaction with all substances in their standard states.

$2CO_2(g)+2H_2O(l)\rightarrow C_2H_4(g)+3O_2(g)$ $\Delta H=+1411.1kJ$

Reversing the reaction, changes the sign of $\Delta H$

$C_2H_4(g)+3O_2(g)\rightarrow 2CO_2(g)+2H_2O(l)$

$\Delta H=-1411.1kJ$

On multiplying the reaction by $\frac{1}{2}$ , enthalpy gets half:

$0.5C_2H_4(g)+1.5O_2(g)\rightarrow CO_2(g)+H_2O(l)$ $\Delta H=\frac{1}{2}\times -1411.1kJ=-705.55kJ/mol$

Thus the enthalpy change for the given reaction is -705.55kJ

Colloid

Explanation:

A lotion of this type is a typical colloid mixture.

A colloid is a homogeneous mixtures of two phases.
The dispersed phase and the dispersion medium.
Water is the dispersion medium and oil is the dispersed phase.

They have the following properties:

Liquid dispersed phase and liquid dispersion medium forms an emulsion and a lotion of this type is an example.
The particles are larger than those found in solutions.
The particles pass through ordinary filter paper.
They may be cloudy or clear .
