Answer:
Higher melting and boiling points signify stronger noncovalent intermolecular forces. Consider the boiling points of increasingly larger hydrocarbons. More carbons means a greater surface area possible for hydrophobic interaction, and thus higher boiling points.
Answer:
Hydrogen is the lightest element in the periodic table. Hydrogen is a gas of diatomic molecules and is colorless, odorless, non-toxic, and highly combustible. It is the most abundant chemical substance in the universe as it constitutes roughly 75% of all normal matter.

Answer:
Formation of Gas, Color Change, and Absorption of heat is the Answer.
Explanation:
I just took the test.
Answer:
C = 0.2349 J/ (g °C)
Explanation:
Mass, m = 894.0g
Initial Temperature = −5.8°C
Final Temperature = 17.5°C
Temperature change = 17.5°C - (−5.8°C) = 23.3
Heat, H = 4.90kJ = 4900 J
Specific heat capacit, C = ?
The relationship between these quantities is given by the equation;
H = mCΔT
C = H / mΔT
C = 4900 / (894)(23.3)
C = 0.2349 J/ (g °C)
