ivolga24 [154]3 years ago
7 0

Answer:

d = 2.5 g/L

Explanation:

Given data:

Molar mass of gas = 56 g/mol

Density of gas = ?

Temperature = 273.15 K

Pressure = 1 atm

Solution:

Formula:

d = PM/RT

d = 1 atm × 56 g/mol / 0.0821 atm.L/mol.K ×273.15 K

d = 56 atm  g/mol./ 22.42 atm.L/mol

d = 2.5 g/L

If the equilibrium concentration of CO is 3.4 × 10–1 M, and the equilibrium concentration
Irina18 [472]

Answer:

4.1M = [CH₃OH]

Explanation:

The equilibrium produced for the reaction between CO and H₂ to form CH₃OH is:

CO + 2 H₂ ⇄ CH₃OH

Where Keq is defined as:

Keq = 26 = [CH₃OH] / [CO] [H₂]²

<em>For concentrations in equilibrium</em>

Replacing in Keq the equilibrium concentrations of CO and H₂, the equilibrium concentration of CH₃COOH is:

26 = [CH₃OH] / [3.4x10⁻¹M] [6.8x10⁻¹M]²

<em>4.1M = [CH₃OH]</em>

malfutka [58]

The correct answer is Ozone.

Ozone, sometimes known as O3, is a poisonous and unstable gas. Ozone is a potent allotrope of oxygen; it absorbs heat when it is present in large quantities all over the earth. A molecule called ozone has three oxygen atoms in it. At ground level, it is dangerous and unstable. O3 O3's efficacy in treating infections, wounds, and several disorders has been extensively established. Before the turn of the century, it was employed to sterilize drinking water. One study found that ozone could cure 114 different ailments. Headaches, coughing, a dry throat, difficulty breathing, a heavy feeling in the chest, and fluid in the lungs can all be side effects of ozone exposure.
