Pentane is the correct answer the prefix pent means 5 so 5 hydrogens
Answer:
Q= mc∆T(ice) + mLF(ice) + mc∆T(water) + mLV(water) + mc∆T(steam)
m=250 g = 0.25 kg = ¼ kg c(ice)= 2100 J/kg.K c(water)= 4200 J/kg.K LF(ice)= 333.7 kJ/kg LV(water)= 2256 kJ/kg c(steam)= 2080 J/kg.K
Explanation:
Q= ¼ × 2100 × (0°-(-30°)) + ¼ × 333700 + ¼ × 4200 × (100°-0°) + ¼ × 2256000 + ¼ × 2080 × (145°-100°)
Q= 15750 + 83425 + 105000 + 564000 + 23400
Q= 791575 J
Answer:
Finches after drought had stronger and larger beaks to demolish the harder and larger seeds that the drought brought, a difference from those that lived in wet times that had smaller, pointy beaks to eat smaller seeds.
Explanation:
This is called the theory of animal evolution, where animals adapt according to the environment, this theory was just analyzed by this species of animals and many more on the island of Galapagos by Darwin.
What I also approve of as that animal that survives a certain environment is the one that is considered most suitable to live in that place.
