Answer:
Alkene A is more stable than alkene B
Explanation:
Complete question:
The same alkane is obtained from the catalytic hydrogenation of both alkene A and alkene B. The heat of hydrogenation of alkene A is 29.8 kcal/mol, and the heat of hydrogenation of alkene B is 31.4 kcal/mol. Which alkene is more stable ?
Step 1: Data given
The heat of hydrogenation of alkene A is 29.8 kcal/mol
The heat of hydrogenation of alkene B is 31.4 kcal/mol
Step 2: Which alkene is more stable
The smaller the heat of hydrogenation, the more stable the alkene. This because it releases less heat, and has less energy.
29.8 < 31.4
This means alkene A has a smaller heat of hydrogenation than alkene B
Alkene A is more stable than alkene B
Answer: True
Explanation: Specific Gravity of a body, also called its Relative Density, is the ratio of the density of that body to the density of a reference material (usually water).
With the Mathematics done right, it is evident that the specific gravity of a body would be equal to the ratio of mass/weight of the body to the mass/weight of an equal volume of water.
S.G = (Density of body)/(Density of water)
Density of Body = (mass/weight of body)/(volume of body)
Density of water = (mass/weight of water)/(volume of water)
If volume of Body = Volume of water, then,
S.G = (Mass/Weight of body)/(Mass/Weight of equal volume of water)
Proved!!
Probably not, because when you're dead, you lose your 'soul'. Like, if you cut out someones heart and put it in someone's body, then yeah, it could work, after a certain time. However, a zombie's body is completely dead, so all the nerves are dead and such. It's just scientifically impossible.
The answer to this question is 4-7
Answer: Option d. pressure increase by a factor of 3
Explanation:
P1 = P
T1 = 300k
T2 = 900K
P2 =?
Volume is constant.
P1/T1 = P2/T2
P/300 = P2/900
P2 x 300 = P x 900
P2 = (P x 900)/300
P2 = 3P
The pressure increased by a factor of 3
