6.37/ 58.5= .108888889
Since it had 3 sig figs the answer is 0.109
when an atom gains or loses an electron, it becomes an ion. Ions formed by the loss of an electron have a positive charge, and those formed by gaining an electron have a negative charge. Positive ions are called cations, and negative ions are called anions.
Answer:
5.0 moles.
Explanation:
- The balanced equation of the reaction between hydrogen and oxgen to produce water is:
<em>H₂ + 1/2O₂ → H₂O.</em>
- It is clear that 1.0 mole of H₂ reacts with 0.5 mole of O₂ to produce 1.0 mole of H₂O.
∴ 2.5 mole of O₂ will react with 5.0 moles of H₂.
- The limiting reactant is O₂ and H₂ is found in excess (1.0 mole more).
From the stichiometry: 2.5 mole of O₂ will react with 5.0 moles of H₂ to produce 5.0 moles of H₂O.
<em>∴ 5.0 moles of water are produced when 6.0 moles of hydrogen gas react with 2.5 moles of oxygen gas</em>
The answer of this question is Oxygen
CrF3; Cr has a 3+ charge and F has a 1-.
