Answer:
127529 KJ
Explanation:
Since 1gallon = 3.78 L= 3780 ml
The density of C8H18= 0.703 g/mL
Density = mass/volume
Mass= Density × volume
Mass= 0.703 g/mL × 3780 ml
Mass= 2657.34 g
Molar mass of C8H18= 114 g/mol
Number of moles= mass/molar mass
Number of moles= 2657.34/114
Number of moles= 23.31 moles
Since 1 mole evolved=5471 kJ
23.31 moles = 5471 kJ × 23.31 = 127529 KJ
Answer:
no
Explanation:
you would need an electron microscope to see atoms.
Answer:
protists that produce a hard outer covering have left many fossils, other protists lack hard parts, so few fossils of these organisms have been found. ... Protists in this group are called plantlike because, like plants, they contain the pigment chlorophyll in chloroplasts and can make their own food.
