Answer:

Explanation:

2 NO2(g) ⇄ N2O4(g)

Adding Argon to this reaction will have NO effect. Catalysts nor inert gases have an affect on equilibrium conditions.

Only changes in concentration, temperature conditions and pressure-volume conditions (unless both sides have equal molar volumes) will affect the equilibria.

NH4OH(aq) ⇄ NH3(g) + H2O(l)

Removing ammonia from reaction equilibrium causes the reaction to shift right to replace removed ammonia. => Think of the reaction as being on a seesaw => removing ammonia from the product side tilts the seesaw left causing the NH₄OH to decompose and deliver more NH₃ and H₂O to the product side to increase weight on that side and level the seesaw. :-)

The rate law of the reaction NH3 + HOCl → NH2Cl + H2O is rate = k[NH3][HOCl] with k = 5.1 × 106 L/mol·s at 25°C. The reaction is

SIZIF [17.4K]

Answer:

40% of the ammonia will take 4.97x10^-5 s to react.

Explanation:

The rate is equal to:

R = k*[NH3]*[HOCl] = 5.1x10^6 * [NH3] * 2x10^-3 = 10200 s^-1 * [NH3]

R = k´ * [NH3]

k´ = 10200 s^-1

Because k´ is the psuedo first-order rate constant, we have the following:

b/(b-x) = 100/(100-40) ; 40% ammonia reacts

b/(b-x) = 1.67

log(b/(b-x)) = log(1.67)

log(b/(b-x)) = 0.22

the time will equal to:

t = (2.303/k) * log(b/(b-x)) = (2.303/10200) * (0.22) = 4.97x10^-5 s

An acid solution contains more... ions than... ions.

spayn [35]

Answer: An acid contains more hydrogen ions than hydroxide ions.

Explanation:

An acid is defined as the chemical compound which has a high concentration of hydrogen ions. They are considered as proton donors and they act as proton $(H^+)$ donors when they have high concentration of hydrogen ions.

A base is defined as a chemical substance which has high concentration of hydroxide ions. They are considered as proton acceptors and they act as proton $(H^+)$ acceptors when they have low concentration of hydrogen ions.

Hence, an acid is contains more hydrogen ions than hydroxide ions.

When comparing the two elements ga and as , the element with the higher first ionization energy is as based on periodic trends a

Nataliya [291]

He, ne , Ar - Noble gas elements have the highest ionization energy,
while francium (87) has the lowest ionization energy because it is so far from helium, in short atom near to helium has higher ionization energy and the atom who is far away from helium have low ionization energy.
