Answer:

Gunshot residue is important to forensic scientists because it can help measure the firing distance of a weapon, or if someone has fired a weapon lately based on what's on their hands. The potential complications of this evidence include it being uncertain if the residue is from another firing. This type of evidence can also be uncertain in a courtroom when firing distance is drawn into question.

Now moles: _(1, 2, or 3)_moles of H2 + _(1, 2, or 3)_ moles of O2 → _(1, 2, or 3)_moles of H2O
arsen [322]

Answer:

2H₂ + O₂ → 2H₂O.

Explanation:

  • For the reaction of water formation:

<em>2H₂ + O₂ → 2H₂O.</em>

  • It should apply the the law of conservation of mass that the no. of reactants atoms is equal to the no. of products atoms.

<em>So, every </em><em>2.0 moles of H₂ </em><em>react with </em><em>1.0 mole of O₂</em><em> to produce </em><em>2.0 moles of H₂O.</em>
