Two neutral atoms, one being a nonmetal and the other a metal, form an ionic bond when the nonmetal uses energy to remove valence electrons from the metal.
Since a metal is not very electronegative but a nonmetal is, the nonmetal can remove the metal’s valence electrons.
In a perfect scenario, both atoms, now ions, will have octets. An octet is formed when an ion has a full valence shell (usually noted with 8 valence electrons).
Explanation: Chemicals in the original manufacturer’s container that have been recently purchased from a supplier will most likely contain hazard information in the form of warnings and pictograms. Older manufacturer’s chemical containers may have alternative labeling schemes that provide essentially the same information as the new labels.
Answer:
0.057 M
Explanation:
Step 1: Given data
Solubility product constant (Ksp) for HgBr₂: 2.8 × 10⁻⁴
Concentration of mercury (II) ion: 0.085 M
Step 2: Write the reaction for the solution of HgBr₂
HgBr₂(s) ⇄ Hg²⁺(aq) + 2 Br⁻
Step 3: Calculate the bromide concentration needed for a precipitate to occur
The Ksp is:
Ksp = 2.8 × 10⁻⁴ = [Hg²⁺] × [Br⁻]²
[Br⁻] = √(2.8 × 10⁻⁴/0.085) = 0.057 M
put some water out with less salt and then some more water out with more salt and look at the differences with the freezing.
It begins to form ice and also on its tail that is ice mixed with rocks and junk but if t where to crash on earth it would come through the atmosphere causing in to burn at amazing speeds. <span />
