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

How are the atoms of carbon different from the atoms of nitrogen
mars1129 [50]
<h2>Answer:</h2>

<em>Per my research, it was said that each of the atoms of the carbon has over 6 protons, six neutrons, and 6 protons. Each atom of nitrogen has 7 protons, 7 electrons, and 7 neutrons. The atomic mass of carbon and nitrogen is 12 and 14 respectively. As the number of electrons in the atoms of the two elements is different they have different chemical properties.</em>

<h2>Explanation:</h2>

<em>As you may know, I did my research and this is what it gave me. I would suppose it is correct since it explains that the carob has over 6 protons and so on. Correct me if I am incorrect and I hope this helped. Have a good one!</em>

Alla [95]
The law of conservation of energy is one of the most commonly used principles in physics and chemistry wherein it states that "Energy<span> can neither be created nor destroyed; rather, it transforms from one form to another." Therefore, the energy entering the system, should be equal to the amount of energy leaving the system.</span>
