Copper II oxide is a compound.
(a)
Write balanced half-reactions for the process:
Oxidation: Se^2- (aq) → Se
(s) + 2e-
Reduction: 2So3^2- (aq) + 3H2O (l) + 4e- →
S2O3^2- + 6OH- (aq)
(b)
If E sulfite is 0.57 V, calculate E selenium:
E anode = E cathode – E cell
= -0.57 – 0.35
=
-.092
Answer: <span>The main interactions between molecules of hydrogen chloride are examples of
Dipole-Dipole Interactions.
Explanation: The bond between Hydrogen and Chlorine is
Polar Covalent Bond as the
electronegativity difference between these two elements is
0.96 which is greater than 0.4. Chlorine being more electronegative attracts the electrons from Hydrogen making the Hydrogen
partial positive and itself
partial negative. The two poles on HCl makes it a dipole. Now, one HCl (a dipole) interacts with another HCl (another Dipole) through their opposite charges and creates
Dipole-Dipole Interaction. The picture is as below, the
green dashed lines are interactions,

According to research, the answer is no. Although alcohol is dissolves in water solution but dissociation of methyl alcohol in into ions is barely not possible. Thus, methanol is considered as a non-electrolyte.
Answer:
the heat energy is transformed to any kind of energy depending on what it's meant to be transformed to.
remember it cannot be destroyed so it's definitely transformed to some kinda energy
