Orchids attract insects many different ways depending on the insect that they attract. Orchids attract flies by using the smell of rotten flesh. Gross right? Anyways another way they can attract insects is because of the shape of their petals. Some males insects think that their petals look like female insects and the male insect then lands on the petal and spreads pollen onto the flower Hope this helped - Ashlynn

NaHCO3 (s) + HC2H3O2 (aq) = NaC2H3O2 (aq) + H2O (I) + CO2 (g)
Misha Larkins [42]

Moles=volume*concentration   
         =0.1*.83
         =.083 Moles of HC2H3O2
Mole ratio between HC2H3O2 and CO2 is 1:1
This means .083 Moles of CO2

Mass =Moles*Rfm of CO2
         =.083*(12+16+16)

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
