I would say that the first answer choice makes sense since the charge of Oxygen is +2. But I may be wrong, try it out!
Answer:
The final temperature is equal to 240 K or -33.15°C
Explanation:
Given that,
Initial temperature of the gas, T₁ = 47°C = 320 K
Initial pressure, P₁ = 140 kpa
Final pressure, P₂ = 105 kpa
We need to find the final temperature if the volume remains constant. The relation between temperature and pressure is given by :
or
So, the final temperature is equal to 240 K or -33.15°C.
On the first graph the beginning flat line is the reaction. Then comes the hill will it be call the activation energy. The final flat line would be the produce. Same names apply to the 2 graph too
Alcohol is the technical, scientifically correct term for the “liquor” alcohol substances for which the general formula is CnH2n+1OH.
Answer:
25.30 gram
Explanation:
No of moles = given mass / molar mass
No of moles = 63.17/80.06
0.7890 moles
Mass of sulphar = no of moles× molar mass of sulphar
Mass of sulphur = 0.7890×32.065
25.30 gram
