Front

What is the number of Carbon-Carbon single bonds formed in a molecule with 2 carbon atoms?

Back

2

Front

In an endothermic reaction, how do the bonds formed in the products compare to the reactant bonds?

Back

The bonds formed in the products are weaker/less stable than the reactant bonds.

Front

What type of process occurs when there is an increase in separation between ions in a solute during dissolution?

Back

Endothermic.

Front

What is the formula for calculating the change in enthalpy for a reaction?

Back

ΔH_rxn = ΔH_products - ΔH_reactants

Front

In an exothermic reaction, how do the bonds formed in the products compare to the reactant bonds?

Back

The bonds formed in the products are stronger/more stable than the reactant bonds.

Front

Define endothermic reaction.

Back

A reaction that absorbs heat from the surroundings.

Front

Define exothermic reaction.

Back

A reaction that releases heat to the surroundings.

Front

What is the significance of ΔH in a chemical reaction?

Back

ΔH represents the change in enthalpy, indicating whether a reaction is endothermic or exothermic.

Front

What happens to the energy during an endothermic reaction?

Back

Energy is absorbed from the surroundings.

Front

What happens to the energy during an exothermic reaction?

Back

Energy is released to the surroundings.
