Hydrogen sulfide gas gives rotten eggs their terrible odor. Hydrogen sulfide burns in air (O2) to produce sulfide dioxide gas an
gizmo_the_mogwai [7]

Answer:

2.07 mol O₂

Explanation:

First we need to write down the species present in the chemical equation, using the information given by the exercise:

  • H₂S + O₂ → SO₂ + H₂O

However this equation <em>is not balanced</em>, so now we<u> balance it</u>:

  • 2H₂S + 3O₂ → 2SO₂ + 2H₂O

Now we can use the stoichiometric ratio to <u>calculate the moles of oxygen </u>from the moles of sulfide dioxide:

  • 1.38 molSO₂ * \frac{3molO_{2}}{2molSO_{2}} = 2.07 mol O₂

The boiling point of isopropyl alcohol is 82.5°C. a student conducts an experiment and finds a boiling point of 83.1°C. what is
zlopas [31]

Answer:

B. 0.7%

Explanation:

Given data:

Actual boiling point = 82.5°C

Experimental boiling point = 83.1°C

Percent error = ?

Solution:

Formula:

Percent error = ( actual value - experimental value / actual value )×100

by putting values,

Percent error = (82.5°C - 83.1 °C /82.5°C) × 100

Percent error = 0.007 × 100

Percent error = 0.7 %

Negative sign shows that experimental value is greater than accepted value. It can not written in result.
