Answer:
See attachment.
Explanation:
Mono-substituted cyclohexanes are more stable with their substituents in an equatorial position. However, with poly-substituted cyclohexanes, the situation is more complex since the steric effects of all substituents have to be taken into account. In this case, you can see that <u>the interconversion is shifted towards the conformation in the bottom because there is less tension between the substituents</u>.
A. Bacteria are stored in the lymph nodes
Zn and HCl are the reactant in the equation above. zinc react with 2 moles of Hcl to form zinc chloride and a hydrogen molecule. The one equation means that the reaction proceed to the forward side only therefore no reverse of the reaction.
Effective collisions are those that result in a chemical reaction. In order to produce an effective collision, reactant particles must possess some minimum amount of energy. This energy, used to initiate the reaction, is called the activation energy.
Answer:
An endothermic reaction
Explanation:
A positive sign indicates that energy is absorbed. Hence it is an endothermic reaction.
A reversible reaction is indicated by a double arrow on the chemical equation.
A spontaneous is indicated by negative Gibbs Free Energy (G) value.
An exothermic reaction is indicated by a negative enthalpy change
