The correct name for the compound N₂O₃ is *

bearhunter [10]

Answer:

Dinitrogen trioxide.

Explanation:

The correct name for the compound $N_2O_3$ is dinitrogen trioxide. The compound $N_2O_3$ also happens to be a <em>covalent compound</em>, and the nomenclature of covalent compounds involves the usage of numerical prefixes such as <em>"mono-"</em> and <em>"tri-"</em>.

Since there are two nitrogen atoms in the compound $N_2O_3$ , we can use the numerical prefix "di-", meaning two, to signify that.

Since there are three oxygen atoms in the compound $N_2O_3$ , we can use the numerical prefix "tri-", meaning three, to signify that.

For chemical reactions involving ideal gases, the equilibrium constant K can be expressed either in terms of the concentrations

miskamm [114]

Answer:

$K_p= 3966.01$

Explanation:

The relation between Kp and Kc is given below:

$K_p= K_c\times (RT)^{\Delta n}$

Where,

Kp is the pressure equilibrium constant

Kc is the molar equilibrium constant

R is gas constant

T is the temperature in Kelvins

Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)

For the first equilibrium reaction:

$2CH_4_{(g)}\rightleftharpoons C_2H_2_{(g)}+3H_2_{(g)}$

Given: Kc = 0.140

Temperature = 1778 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T = (1778 + 273.15) K = 2051.15 K

R = 0.082057 L atm.mol⁻¹K⁻¹

Δn = (3+1)-(2) = 2

Thus, Kp is:

$K_p= 0.140\times (0.082057\times 2051.15)^{2}$

$K_p= 3966.01$
