Answer:
The system shifts forward
Explanation:
The forward reaction is favoured in order to reduce the disruption (excess heat) to the system. Position of equilibrium shifts rightwards of the equation for excess heat to be absorbed during the endothermic forward reaction
Answer:
Zn(s) + Cu²⁺(aq) ⇒ Zn²⁺(aq) + Cu(s)
Explanation:
Let's consider the molecular single displacement equation between Zn and Cu(NO₃)₂
Zn(s) + Cu(NO₃)₂(aq) ⇒ Zn(NO₃)₂(aq) + Cu(s)
The complete ionic equation includes all the ions and insoluble species.
Zn(s) + Cu²⁺(aq) + 2 NO₃⁻(aq) ⇒ Zn²⁺(aq) + 2 NO₃⁻(aq) + Cu(s)
The net ionic equation includes only the ions that participate in the reaction and insoluble species.
Zn(s) + Cu²⁺(aq) ⇒ Zn²⁺(aq) + Cu(s)
CCl₄ - carbon tetrachloride
This molecule has 4 polar bonds, but is non-polar in nature.

The balanced equation for the combustion reaction is as follows
4C₂H₅ + 13O₂ --> 8CO₂ + 10H₂O
coefficients for the reactants and products are
C₂H₅ - 4
