Lead is heavier and more resistant. Plastic foam is light and can easily be broken
Answer:
3
Step-by-step explanation:
Hence, the given number has 3 significant figures.
C3H6 because the molar mass of CH2 is 14 g/mol, but to get how many moles it takes to get to 42 g/mol, you need to divide 42 by 14 and that gets you 3 moles.
Fossils are usually found in sedimentary rocks.
Answer:
The answer to your question is E = 419.435 J
Explanation:
Data
Mass = m = 2.004 g
Temperature 1 = T1 = 89°C
Temperature 2 = T2 = 139°C
Specific heat of water = Cp = 4.186 J/g°C
Energy = E = ?
Formula
E = mCp(T2 - T1)
Substitution
E = (2.004)(4.186)(139 - 89)
Simplification and result
E = 8.3887(50)
E = 419.435 J
