Answer:
2OH^-(aq) + Cu^2+(aq) -----> Cu(OH)2(s)
Explanation:
The net ionic equation usually shows the main ionic reaction that goes in the system. The other ions that do not participate in this net ionic equation are called spectator ions. Spectator ions do not participate in the main reaction occurring in the system.
The net ionic equation quite often result in the formation of a solid precipitate in the system such as Cu(OH)2.
The net ionic equation for this reaction is;
2OH^-(aq) + Cu^2+(aq) -----> Cu(OH)2(s)
The answer is Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded. The metallic bond structure of lead forms a cubic crystal structure and the atoms can roll over one another without breaking the metallic bonds. This is especially because the p orbital electrons of lead can be delocalized and the electrons can be shared with other lead ions in the cubic structure of lead.
Answer:
1. When you see the moon, think of the whereabouts of the sun
2. The moon rises in the east and sets in the west, each and every day
3. The moon takes about a month (one month) to orbit the Earth
4. The moon’s orbital motion is toward the east
Explanation:
Answer:
Concentration for the solution is 0.153 mol/L
Explanation:
Formula for the osmotic pressure is π = M . R . T . i
where M is molarity (concentration), R the universal constant for gases and T is Absolute T° (T°C + 273)
π = Osmotic pressure.
Let's replace the data given:
3.9 atm = M . 0.082L.atm/mol.K . 310K
3.9 atm / 0.082 mol.K/L.atm . 310K = 0.153 mol/L (M)
i = Van't Hoff factor (ions from the solute dissolved in solution)
In this case, we assumed no ion pairing, so i = 1
