Hey there!
Mn + HI → H₂ + MnI₃
Balance I.
1 on the left, 3 on the right. Add a coefficient of 3 in front of HI.
Mn + 3HI → H₂ + MnI₃
Balance H.
3 on the left, 2 on the right. Multiply everything else by 2.
2Mn + 6HI → H₂ + 2MnI₃
Now we have 6 on the left and 2 on the right. Add a coefficient of 3 in front fo H₂.
2Mn + 6HI → 3H₂ + 2MnI₃
Balance Mn.
2 on the left, 2 on the right. Already balanced.
Our final balanced equation:
2Mn + 6HI → 3H₂ + 2MnI₃
Hope this helps!
Answer:
2 Na: 1 O
Explanation:
2 Sodium ion per 1 Oxygen ion
Answer:
The molarity of the solution is 0.29
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
Molarity is expressed in units .
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:
Molarity= 0.29
<u><em>The molarity of the solution is 0.29 </em></u><u><em></em></u>
