PLZ HELP For the reaction: 2NO2(g) → N2O4(l),

Furkat [3]

Answer: $\Delta H_{rxn}=-20kJ/mol-(+66kJ/mol)$

Explanation:

Heat of reaction or enthalpy change is the energy released or absorbed during the course of the reaction.

It is calculated by subtracting the enthalpy of reactants from the enthalpy of products.

$\Delta H=H_{products}-H_{reactants}$

$\Delta H$ = enthalpy change = ?

$H_{products}$ = enthalpy of products

$H_{reactants}$ = enthalpy of reactants

For the given reaction :

$2NO_2(g)\rightarrow N_2O_4(l)$

$\Delta H=H_{N_2O_4}-2\times H_{NO_2}$

$\Delta H=-20kJ/mol-(+66kJ/mol)$

Bubbles in soda rise to the surface. Explain this in terms of density.

algol [13]

Answer:

Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them. This is just like helium in air; helium is lighter than air, so it rises, pushed to the top by the pressure around it.
