Among BF₃, NF₃, OH⁻ and ALCl₃ both NF₃ and OH⁻ acts as a lewis base.
Explaination:
According to lewis theory of acid and base, base is a specie which has either lone pair of electrons or is negatively charged. So, in the given compounds Nitrogen trifluoride contain lone pair of electron on nitrogen and Hydroxide contains a negative charge on oxygen. And botha are capable to donate these electrons to a lewis acid (electrophiles).
Answer:
2.67g Ni
Explanation:
To convert from moles to mass, use molar mass as a conversion factor.
Nickel has a molar mass of 58.69g/mol.
0.0455mol (
) = 2.67g Ni

Answer:
Explanation:
This is a typical double replacement or double decomposition reaction. In this kind of reaction, it involves the combination of ionic compounds which exchange their partners to form new compounds. Typical of these reaction is the formation of precipitates which are insoluble compounds.
The reaction equation is shown below:
AgNO₃
+ K₂SO₄ → 2KNO₃ + AgSO₄
)
From the rule of solubility:
- All trioxonitrate(v) salts are soluble
- Salts of silver sulfates are slightly soluble. This will form the precipitate in the solution.
We can write the ionic equation as:
Ag⁺ + NO₃⁻ + 2K⁺ + SO₄²⁻ → AgSO₄
+ 2K⁺ + NO₃⁻
The spectator ions or non-reactive ions are those ions that appears on both sides of the equation. These ions are the potassium and trioxonitrate ions. We cancel them out to give the net ionic equation of the reaction:
Ag⁺ + SO₄²⁻ → AgSO₄
Answer:
The equilibrium will shift in forward direction.
Explanation:
The equilibrium between the carbonic acid and bicarbonate ion is shown below as:
H₂CO₃ (aq) ⇔ H⁺(aq) + HCO₃²⁻(aq)
According to Le Chatelier's Principle, the change in any state of the equilibrium say temperature, volume, pressure, or the concentration, the equilibrium will oppose these changes and will shift in such a way that the effect cause must be nullified.
<u>If a strong base is added to the equilibrium, the base will accept hydrogen ions which are formed in the right side of the equilibrium. Thus, there will be less hydrogen ions present and to compensate this effect, the equilibrium will shift in forward direction.</u>
