Explanation:
Pb2O3 is better formulated as PbO.PbO2. It is actually a mixture of the two oxides of lead, lead II oxide and lead IV oxide.
This implies that this compound Pb2O3 (sometimes called lead sesquioxide) is a mixture of the oxides of lead in its two known oxidation states +II and +IV.
Hence Pb2O3 contains PbO and PbO2 units.
Answer:
moles of water in 1 ml = 1/18 mol.
take 1 ml and calculate it by 30
1 ml x 30= 30 ml
Explanation:
Alkali metals will always contain one valence electron but the electron configuration will depend on the element
non-metals are brittle.
but for brittle property, they need to be solid.
sulphur is solid at STP.
Argon(Ar) is a gas at STP, so it cannot be brittle.
1.covalent bond
2A bond angle is the angle between two bonds originating from the same atom in a covalent species
3. 1.Write the Lewis dot structure for the molecule.
2.Use the steric number and VSEPR theory to determine the electron domain geometry of the molecule.
3. Use the VSEPR shape to determine the angles between the electron domains.
