The correct answer is<span> C) Water takes long to heat and cool down than other liquids.
It doesn't climb up the sides of a tube any more than other solutions do, and being a universal solvent has nothing to do with radiators. It does however take a long time to heat and cool down since you don't have a 100+ celsius burner to heat it up in an instant.</span>
Answer:
The answer to your question is: True
Explanation:
Gibbs energy is the energy related to a chemical reaction that can be used to do some work.
Gibbs energy is calculated from a reaction and also the spontaneity can be determined.
In a spontaneous reaction Gibbs energy is always negative.
Answer:
c(Al³⁺) = 0.52 mol·L⁻¹; c(SO₄²⁻) = 0.84 mol·L⁻¹
Explanation:
One mole of aluminium sulfate produces 2 mol of aluminium ions and 3 mol of sulfate ions.
If we apply the same proportionality, 0.26 mol of Al₂(SO₄)₃ produces 0.52 mol of Al³⁺ions and 0.84 mol of SO₄²⁻ ions.
Al₂(SO₄)₃(aq) ⟶ 2Al³⁺(aq) + 3SO₄²⁻(aq)
I/mol·L⁻¹: 0.26 0 0
C/mol·L⁻¹: -0.26 +0.52 +0.84
E/mol·L⁻¹: 0 0.52 0.84
From this, a greater amount of hydrogen bonding can take place between water molecules than between methanol molecules. Thus a greater amount of thermal energy is needed to overcome these intermolecular forces for water, leading to its boiling point being higher than methanol.
