Missing text find on internet: a<span> 90,0 mL sample of water is heated to its boiling point.
V(H</span>₂O) = 90,0 mL.
d(H₂O) = 1,00 g/mL.
m(H₂O) = 90 mL · 1,00 g/mL.
m(H₂O) = 90 g.
n(H₂O) = m(H₂O) ÷ M(H₂O).
n(H₂O) = 90 g ÷ 18 g/mol.
n(H₂O) = 5 mol.
Q = n(H₂O) · ΔHvap
Q = 5 mol · 40.65 kJ/mol.
Q = 203,250 kJ.
Q - heat reqiured.
Octane will have higher melting point
Answer:
3.14
Explanation:
A student was comparing two samples with an equal number of carbon atoms. One sample contained only Carbon-12 atoms. One sample contained only Carbon-14 atoms, which contain two more neutrons than Carbon-12 atoms. The student measured the mass of each sample and testing the reactivity of each sample.
Required:
What would best describe the results of the investigation?
