Answer:
Add some water to his solution
Explanation:
Ion pair effect refers to strong electrostatic interaction between oppositely charged ions in solution. Such strong interaction affects solute- solvent interaction when an ionic substance is dissolved in water.
High solute concentration may lead to ion-pair effect. Hence, the ion pair effect may be minimized by adding more water (decreasing the concentration of the solution).
To reduce the ion- pair effect, Andy needs to add some water to his solution (dilution).
Answer:
NH3 weak base
HCOOH weak acid
H3PO4 weak acid
NaOH strong base
Explanation:
When talking about the weakness or strength of acid and bases, it is essential to look at it from the base point of ionization or dissociation in solutions. For an acid or base to be termed strong , this means it ionize completely in solution to form hydroxonium ion and hydroxide jobs respectively in water. For an acid or base to be termed weak, it ionizes only partially in solution.
The strength of acid can be accessed from the value of the acid ionization constant Ka. Strong acids like sulphuric acid have a fairly large value for for this constant while weak acids have a relatively low value for this constant. Hence, we must know that the dissociation equation is not enough to say an acid is weak or strong. Acids with higher Ka value are stronger with acids with lower Ka value.
In likewise manner, we have the base dissociation constant. It is the equilibrium constant for a base dissociation reaction. While stronger bases have relatively higher values for Ka, weak bases have a relatively lower value.
Ammonia yields a weak base solution of ammonium hydroxide in water. This makes it a weak acid
Methanoic or Formic acid like most organic acid is a weak acid. It ionizes only partially in solutions.
Phosphoric acid is also a weak acid as it ionizes partially in solutions too.
Lastly, sodium hydroxide is a strong base as it ionizes completely in solution
Answer:
NCl₃ + 2 H₂O = HNO₂ + 3 HCl
Explanation:
Let's consider the unbalanced equation showing the reaction between nitrogen trichloride and water to form nitrous acid and hydrochloric acid.
NCl₃ + H₂O = HNO₂ + HCl
We start balancing Cl atoms by multiplying HCl by 3.
NCl₃ + H₂O = HNO₂ + 3 HCl
Then, we balance O atoms by multiplying H₂O by 2.
NCl₃ + 2 H₂O = HNO₂ + 3 HCl
The equation is now balanced.

Displacement is zero. Displacement is in reference to the starting and ending positions, so starting and ending in the same place would cause a net displacement of zero. Distance, however, is not zero. It is a measurement of the total amount moved, so if the object left the starting position, the distance is automatically not zero.
