<span>Ionic bonding is the entire exchange of valence electron(s) between particles. It is a kind of substance security that creates two oppositely charged particles. In ionic bonds, the metal loses electrons to wind up plainly an emphatically charged cation, though the nonmetal acknowledges those electrons to end up noticeably a contrarily charged anion.</span>
Answer:
7.0*10-11m or 70Å
Explanation:
From Bragg's equation, w=2dsinx/n
Since all the parameters are specified in the question, we can easily go ahead to obtain the wavelength but we must convert the spacing given in angstroms to meters using the conversion factor provided as shown in the solution below:
Net ionic reaction for the solution containing equal concentrations of both HF(aq) and NaF(aq) is as follow:
F⁻(aq) + H₂O(l) ⇄ HF(aq) + OH⁻(aq)
Answer:
71.5 %
Explanation:
mercury + bromine ⟶ compound
Mass/g: 60.2 24.0
According to the <em>Law of Conservation of Mass</em>, the mass of the product must equal the mass of the reactants
Mass of product = 60.2 + 24.0
Mass of product = 84.2 g
The formula for <em>percent composition</em> is
% by mass = mass of component/total mass × 100 %
% Hg = 60.2/84.2 × 100
% Hg = 0.7150 × 100
% Hg = 71.5 %
