Answer:
Moles= 10.55*10^29ǜ.02*10^23
=1.75*10^6 moles
Moles= mass/molar mass
1.75*10^6=mass/ 183
Mass= 320*10^6 g
Answer:
Cuando un átomo neutro gana uno o más electrones, el número de electrones aumenta mientras que el número de protones en el núcleo permanece igual. El resultado es que el átomo se convierte en un anión, un ion con una carga neta negativa.
Explanation:
When the acid is hydrolyzed, the reaction is
HA --> H⁺ + A⁻
So,
Ka = [H⁺][A⁻]/[HA]
Apply the ICE approach:
HA --> H⁺ + A⁻
I 0.3 0 0
C -X +X +X
E 0.3-X X X
Ka = [X][X]/[0.3-X]
X = H⁺ = A⁻
The formula for pH is:
pH = -log[X]
5.2 = -log[X]
Solving for X,
X = 6.31*10⁻⁶
Therefore,
Ka = [6.31*10⁻⁶][6.31*10⁻⁶]/[0.3-6.31*10⁻⁶]
<span>Ka = 1.33×10⁻¹⁰</span>
Carbon, Lead and Silicon all have the same amount of valence electrons as Germanium. This can be determined by looking at their position on the periodic table. Within each column (group) all the elements have the same amount of valence electrons. This explains why they will all have very similar chemical properties.
Well you see its part sodium and sodium is another word for salt so It is a salt because it is formed by the reaction of an acid and a base
