Explanation:
Answer:

Explanation:
Hello,
In this case, we can analyze the colligative property of solutions - freezing point depression - for the formed solution when ethylene glycol mixes with water. Thus, since water freezes at 0 °C, we can compute the freezing point of the solution as shown below:

Whereas the van't Hoff factor for this solute is 1 as it is nonionizing and the molality is:

Thus, we obtain:

Best regards.
Explanation:
It is the motion of particles that creates a form of energy called heat (or thermal) energy that is present in all matter. Tiny particles in solids, liquids and gases are always in motion. It is the motion of particles that creates a form of energy called thermal (heat) energy that is present in all matter.
Answer:
Fe + CuSO4 → Cu + Fe2(SO4)
2. Combine lead (II) nitrate and potassium iodide solutions.
Pb(NO3)2+ Kl → KNO3 + PbI2
3. Combine magnesium metal and hydrochloric acid solution.
Mg + HCl → MgCl 2(aq) + H 2(g)
4. Electrolysis (splitting) of water.
H2O → Im not sure sorry
5. Burning magnesium.
Mg + O2 → MgO
