First you would multiply 5,3, and 2 to get a volume of 30. Density is mass over volume so you would then divide 129 by 30. You would get 4.3. The answer would be 4.3 g/cm^3
The answer is yes they do form ions upon gaining electrons and becomes negatively charged
Answer:
I₂ + H₂O --------→ HI + HIO
Explanation:
Iodine is not fully dissolve in water but only dissolve up to some extent.
When iodine was mixed with water it give mixture of two products.
- Hydrogen iodide or hydroiodic acid (HI)
- Hypoiodous acid (HIO)
So the balance reaction is as under
I₂ + H₂O --------→ HI + HIO
All the reactant are one mole and one one mole of each product produced in the shown reaction.
This is a reversible reaction and only 0.05% of Iodine molecule react with water and the other Iodine molecule remain in water unreacted.
Answer:
MgO, is similar to the bonding in barium chloride, BaCl2. The bonding in each compound involves a transfer of valence electrons from the metal to the nonmetal; both metals lose all of their valence electrons
Explanation:
used goggle
Answer:
± 1 or ± 2
Explanation:
Electrovalent bonds are chemical bonds that are established on the premise of transferring electrons between two atoms.
In this bond type, a higly electronegative atom, typically a non-metal receives electrons from an atom with lesser electronegativity, a metal.
To know the number of electrons involved in forming electrovalent bonds, we typically look at the groups of atoms that combines to form the bond.
Metals are found in group I and II on the periodic table. Metals are electropositive and are good electron donors. These metals have 1 and 2 electrons in their valence shell respectively. In like manners, the more electronegative atoms are found in group VI and VII. The elements in these groups are non-metals with high electronegativity and requires just 1 and 2 electrons to complete their octet.
