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 :

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

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

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

Why is it important to know what temperature scale is being used in a given situation?

Arisa [49]

It depends, for example, it is quite important to know the Kelvin scale (i.e 0 degrees Celsius is 273 K and -273 degrees Celsius is 0 K ) when dealing gases. But I don't know other situations where you would need to know other temperature scales.

Hope this helps and also if you are using Fahrenheit 1 Fahrenheit is -17.22 degrees Celsius

A sample of a substance has a mass of 4.2 grams and a volume of 6 milliliters. The density of this substance is

Tanzania [10]

Hello!

Mass =4.2 g

Volume =6 mL

Therefore:

Density = mass / volume

Density = 4.2 / 6

Density = 0.7 g/mL

Hope that helps!
