the reaction between nitrogen and hydrogen to produce ammonia is described by the following equilibrium reaction. 3h2 n2↽−−⇀2nh3
eimsori [14]

N₂, H₂, NH₃ are present in the reaction mixture when equilibrium has been obtained.

Balanced chemical reaction: 3H₂ + N₂ ⇄ 2NH₃

Hydrogen (H₂ ) and nitrogen (N₂) are reactants.

Ammonia (NH₃) is product of the reaction.

Reaction goes in both direction, both reactants and product are present.

The amount of substance of reactants and products of reaction do not change when chemical reaction is in chemical equilibrium.

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which not change with time.

Speed of direct and irreversible chemical reaction are equal.

For a tablet containing 500. mg of vitamin C, calculate how many ml of 0.095 M NaOH is required to reach the equivalence point.
Gala2k [10]

Answer:

mL of NaOH required =29.9mL

Explanation:

Let us calculate the moles of vitamin C in the tablet:

The molar mass of Vitamin C is 176.14 g/mole

moles=\frac{mass}{molarmass}=\frac{500mg}{176.14}=\frac{0.5}{176.14}=0.0028

Thus we need same number of moles of NaOH to reach the equivalence point.

For NaOH solution:

moles=MolarityXvolume=0.095Xvolume

0.00283=0.095Xvolume

volume=0.0299L=29.9mL
