As you add more acid to the solution the amount of dissociation increases to compensate for it. But since the acid is weak, it will never have more ions dissociate than are in the concentrated solution being added. % ionization is the concentration of dissociated H+ ions divided by the initial concentration of the weak acid. 

% ionization = [H+] / [weak acid] x 100% 

As you increase the concentration of the weak acid, the numerator increases more than the denominator so the percentage goes down.

A sample of gas contains 0.1900 mol of CO(g) and 0.1900 mol of NO(g) and occupies a volume of 22.0 L. The following reaction tak
worty [1.4K]

Answer:

V₂ = 16.5 L

Explanation:

To solve this problem we use <em>Avogadro's law, </em>which applies when temperature and pressure remain constant:

V₁/n₁ = V₂/n₂

In this case, V₁ is 22.0 L, n₁ is [mol CO + mol NO], V₂ is our unknown, and n₂ is [mol CO₂ + mol N₂].

  • n₁ = mol CO + mol NO = 0.1900 + 0.1900 = 0.3800 mol

<em>We use the reaction to calculate n₂</em>:

2CO(g) + 2NO(g) → 2CO₂(g) + N₂(g)

  • mol CO₂:

0.1900 mol CO * \frac{2molCO_{2}}{2molCO} = 0.1900 mol CO₂

  • mol N₂:

0.1900 mol NO * \frac{1molN_{2}}{2molNO} = 0.095 mol N₂

  • n₂ = mol CO₂ + mol N₂ = 0.1900 + 0.095 = 0.2850 mol

Calculating V₂:

22.0 L / 0.3800 mol = V₂ / 0.2850 mol

V₂ = 16.5 L

The gas in an engine cylinder is compressed until it has a volume of 0.045 liter and an absolute pressure of 28 atmospheres. If
Sonbull [250]

The  temperature  in K  is  767.4 K

<u><em>  calculation</em></u>

This is calculated using the ideal gas equation

that is PV =nRT

where;

P(pressure)= 28 atm

V(volume) = 0.045 L

n(number of moles)= 0.020 moles

R( gas  constant)  =0.0821 L.atm/mol.K

T(temperature)= ? K\


make T the subject of   the formula  by diving  both side of equation by nR

T =PV/nR

T ={ (28 atm x 0.045 L) /( 0.020 mol x 0.0821 L.atm/mol.K)}  =767.4 K
