for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species. Humans and chimps share a surprising 99 percent of their DNA.
Answer: the answer is d
Explanation:
Decane + Dioxygen = Carbon Dioxide + Water
Reaction Type
Combustion
The new pressure exerted by helium on its container is 2533.33 torr.
Boyle's law: For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. so PV= constant.
At constant temperature and moles,
P1V1 = P2V2.
The original sample is at 2atm torr and volume 5.00 L and then helium gas was compressed to 3.00 L
∴ P₁V₁ = P₂V₂
(2× 760 torr)(5.00 L ) = (3.00 L )(x torr),
x = 2533.33 torr.
P₂ = 2533.33 torr.
Therefore, the new pressure exerted by helium on its container is 2533.33 torr.
