Substituents are trans to each other if the appear on opposite sides in the structure. C, E, G, H and K are trans to the bromo substituent.
The substituted cyclohexane compound is shown in the image attached. Two substituents in a compound are trans to each other if they appear on opposite sides of the structure. Cis substituents appear on the same side of the structure.
Considering the structure as shown in the image attached, the substituents that are trans to the bromo substituent are the substituents shown as letters C, E, G, H and K. They lie opposite to the bromo substituent.

Answer:
12
Explanation:
The coefficient of the CO2 shows the amount of CO2 needed in the reaction so to react with 11 water, 12 molecules of carbon dioxide is needed.
V = maximum capacity of human lung = 3 liter = 3 x 0.001 m³ = 0.003 m³ (Since 1 liter = 0.001 m³)
P = pressure of oxygen = 21.1 kilo pascal = 21.1 x 1000 = 21100 Pa (since 1 kilo = 1000)
T = temperature of air = 295 K
n = number of moles of oxygen
Using the ideal gas equation
PV = n RT
inserting the above values in the equation
(21100) (0.003) = n (8.314) (295)
n = 0.026 moles
The theobromine molecule contains a total of 22 bonds
Answer:
Ag2S
Explanation:
10.8 gm of silver, 12.4 gm of silver sulfide, so 12.4 -10.8 = 1,6 gm of sulfur
silver atomic weight is 108, sulfur atomic weight is 32 so
10.8/108; = 0.10 mole Ag 1.6/32 = 0.05 mole sulfur
so there is a 2:1 ratio of silver to sulfur, so the compound is 2 silver 1 sulfur or Ag2S
