Left Panel

A is an acid. Not the answer.

B is correct. That would be a base. But it is not an Arrhenius base. Keep reading.

C that is exactly what an Arrhenius base is.

D. No an acid of some sort would accept OH ions.

Right Panel

D is concentrated and it is also a weak base. Good cleaning fluid. Smells awful but it works.

m_a_m_a [10]

Answer:

1.0 moles of N2

Explanation:

since

1.0 × avogadro's no# = same answer for SO2 and N2

avogadro's no#= 6.02× 10²³

g At elevated temperatures, molecular hydrogen and molecular bromine react to partially form hydrogen bromide: H 2 (g) Br 2 (g)
oksano4ka [1.4K]

Answer: At equilibrium , there are 0.274 moles of Br_2

Explanation:

Moles of  H_2 = 0.682 mole

Moles of  Br_2 = 0.440 mole

Volume of solution = 2.00 L

Initial concentration of H_2 = \frac{0.682}{2.00}=0.341 M

Initial concentration of Br_2 =  \frac{0.440}{2.00}=0.220 M

Equilibrium concentration of H_2 = \frac{0.516}{2.00}=0.258 M

The given balanced equilibrium reaction is,

             H_2(g)+Br_2(g)\rightleftharpoons 2HBr(g)

Initial conc.   0.341 M    0.220 M        0 M    

At eqm. conc.   (0.341-x) M   (0.220-x) M   (2x) M

Given : (0.341-x) M = 0.258 M

x= 0.083 M

Thus equilibrium concentartion of Br_2 = (0.220-0.083) M = 0.137 M

Thus moles of Br_2 at equilibrium = 0.137M\times 2.00L=0.274mol

At equilibrium , there are 0.274 moles of Br_2
