Answer:

bblalabala;;a;;a

Explanation:

What is the heat of reaction for the process NH4CI (s) ----> NH3 (g)+HCI (g)

The reaction taking place is a gas-phase acid-base reaction (both HCl and NH3 are volatile), that produces particulate NH4Cl as the sole product: HCl(g) + NH3(g) → NH4Cl(s). 1.

What pressure is required to achieve a co2 concentration of 5.80×10−2 m at 20∘c?
skelet666 [1.2K]

The concentration (c) of a gas at pressure (p) at a given temperature (T) through the Henry's constant kH

c = kH * p

at 20 C or 293 K, the henry's constant kH for CO2 = 0.037 mol/L-atm

Given concentration c = 0.0580 moles/L

Hence the pressure is given as:

p = c/kH = 0.0580 molesL-1/0.037 molL-1atm-1 = 1.57 atm

Pressure required is 1.57 atm

Acetone can be easily converted to isopropyl alcohol by addition of hydrogen to the carbon–oxygen double bond. calculate the ent
Vanyuwa [196]
<span>Answer: Enthalpy is delta-H- We need to look at the molecule and determine which bonds are broken adn which bonds are formed. Bonds that are broken are H-H (from the H2 molecule) and the C=O from acetone. their energies add up like this: 436 kJ + 745 kJ = 1181 kJ looking at the bonds formed, these are C-O, O-H, and C-H. these add up to 1229 kJ solving for delta H by taking the sum of the broken bonds and subtracting the sum of the formed bonds, like so: 1181 - 1229 = -48 kJ</span>

sergeinik [125]

Answer:

Electrones de valencia.

Explanation:

¡Hola!

En este caso, dado en química se conocen las estructuras de Lewis como representaciones gráficas de como los elementos están enlazados entre sí, debemos tener en cuenta que estos enlaces se forman entre los electrones de valenciam, los cuales son utilizados para su representación. Se sabe que los electrones de valencia son representados con puntos alrededor del elemento a través de puntos que se unen entre sí y son el número de electrons en la capa más externa de los elementos en cuestión; por ejemplo, cloro tiene 7 electrones de valencia, azufre tiene 6, hidrogeno 1, carbono 4 y así sucesivamente.

¡Saludos!
