What is the pressure inside a 2.0 L bottle filled with 0.25 mol of carbon dioxide gas at 25 °C?

Chemistry

Answer:

3.1atm

Explanation:

Given parameters:

Volume of gas = 2L

Number of moles  = 0.25mol

Temperature  = 25°C = 25 + 273  = 298K

Unknown:

Pressure of the gas = ?

Solution:

To solve this problem, we use the ideal gas equation.

This is given as;

       PV  = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas  constant  = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

          P  = \frac{nRT}{V}  

 Now insert the parameters and solve;

         P  = \frac{0.25 x 0.082 x 298}{2}   = 3.1atm

A weak acid (ha) has a pka of 4.001. If a solution of this acid has a ph of 4.110, what percentage of the acid is not ionized? (
OverLord2011 [107]

99.9224 % of the acid is not ionized.

____HA + H₂O ⇌ A⁻ + H₃O⁺

I: ___<em>c</em> ________0 ____0  

C: _-α<em>c</em> _______+α<em>c</em> __+α<em>c </em>

E: <em>c</em>(1-α) _______α<em>c</em> ___α<em>c </em>

pH = 4.110

[H₃O⁺] = α<em>c</em> = 10^(-4.110) mol/L = 7.76 × 10⁻⁵ mol/L

α = 7.76 × 10⁻⁵

1 – α = 1 - 7.76 × 10⁻⁵ = 0.999 224 = 99.9224 %

Calculate the rcf (recipe conversion factor) for a new yield of 80 oz. (5 lbs) blueberry muffin batter. the original yield of th
SCORPION-xisa [38]

The rcf (recipe conversion factor)=  0.6

<h3>What is the rcf (recipe conversion factor)?</h3>
  • The conversion factor approach is the most typical technique for modifying recipes.
  • Finding a conversion factor and multiplying the ingredients in the original recipe by that factor are the only two steps needed to do this.
  • Remember that the conversion factor will be larger than 1 if you are raising your amounts to be sure you are finding it correctly.
  • The factor will be less than 1 if your amounts are being decreased. Use the conversion factor approach if you come across a recipe that is written in a standard format.
  • The production of phenolic monomers from lignin is effective and selective when done using reductive catalytic fractionation (RCF).

How this is calculated?

Conversion Factor = New Yield ÷ Old Yield

 =80/134

 =0.5970

 =0.6(rounded to nearest tenth)
