Si una masa dada de hidrógeno ocupa 40 litros a 700 grados torr. ¿Qué volumen ocupará a 1 atmósfera de presión? (dar la presión
Svetach [21]

Answer:

V_2=36.84L

Explanation:

Hola,

En este caso, podemos usar la ley de Boyle, la cual nos permite analizar el comportamiento volumen-presión en un gas ideal de manera inversamente propocional:

P_1V_1=P_2V_2

Así, dado el volumen y la presión inicial, la cual se convierte a atmósferas (760 torr = 1atm), calculamos el volumen final a 1 atm como se muestra a continuación:

V_2=\frac{P_1V_1}{P_2}=\frac{700torr*\frac{1atm}{760torr}*40l }{1atm}\\  \\V_2=36.84L

Saludos!

What is electronegativity​
Mama L [17]

Answer:

Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

Its symbol is the Greek letter chi: χ

The higher the electronegativity, the greater an atom's attraction for electrons.

Below is a periodic table of electronegativity: the lighter the shade of green, the higher the electronegativity. Gray means no value is known. (Click image for larger view that shows electronegativity values.)

If excess caso4(s) is mixed with water at 25 ∘c to produce a saturated solution of caso4, what is the equilibrium concentration
Ray Of Light [21]

<em>Answer:</em>

The equlibrium concentration sof Ca+2 ion willl be 4.9×10∧-3 M

<em>Data Given:</em>

              Ksp of CaSO4 = 2.4 × 10∧-5

              CaSO4 ⇔ Ca+2   +  SO4∧-2

<em>Solution:</em>

                Ksp = [Ca+2].[ SO4∧-2]

                 2.4 × 10∧-5 = [x].[x]= x²

                 x =  4.9×10∧-3 M

<em>Result:</em>

  • The conc. of Ca+2 ion is 4.9×10∧-3 M

Nitrogen and hydrogen combine to form ammonia in the Haber process. Calculate (in kJ/mole) the standard enthalpy change DH° for
MrRa [10]

Answer: 104 KJ mol

Each NH3 has 3 N-H bonds

Explanation:

Enthalpy change(DHo)= sum t enthalpy of products - sum of enthalpy of Reactants

DHo= 2x3 dHo (N-H) - {dHo(N2)+3dHo(H-H)}

= 6(391)-(945+3(432))

=2346-(945+1296)

=2346-2241

DHo= 105 KJ/mole
