Please check this over and see of they are right...if they are not can you please tell the the right answer and explain how you got it. I think I am getting myself confused. Thank you.
Write the neutralization reaction for each of the following. Balance the equations.
a. HI(aq) + NaOH(aq) ® NaI + H2O
b. HClO4(aq) + Sr(OH)2 ®
2HClO4 + Sr(OH)2 ----> 2H2O + Sr(ClO4)2
IS this right??
They look good to me.
Thank you so much DrBob222
Let's go through each equation and check if they are balanced correctly.
a. HI(aq) + NaOH(aq) → NaI + H2O
The equation represents a neutralization reaction between hydroiodic acid (HI) and sodium hydroxide (NaOH). To balance this equation, we need to ensure that the number of atoms on both sides of the equation is equal.
First, let's count the number of each type of atom on each side:
Left side: H: 1 (HI), Na: 1 (NaOH), I: 1 (HI), O: 1 (NaOH)
Right side: Na: 1 (NaI), I: 1 (NaI), H: 2 (H2O), O: 1 (H2O)
We can see that the equation is not balanced as the hydrogen and oxygen atoms are not equal on both sides. To balance them, we need to adjust the coefficients:
HI(aq) + NaOH(aq) → NaI + H2O
1HI(aq) + 1NaOH(aq) → 1NaI + 1H2O
Now, the equation is balanced correctly.
b. HClO4(aq) + Sr(OH)2 → 2H2O + Sr(ClO4)2
In this equation, we have hydrochloric acid (HClO4) reacting with strontium hydroxide (Sr(OH)2). Again, let's count the number of each type of atom on each side:
Left side: H: 1 (HClO4), Cl: 1 (HClO4), O: 4 (HClO4), Sr: 1 (Sr(OH)2)
Right side: H: 4 (2H2O), Cl: 2 (Sr(ClO4)2), O: 8 (2H2O + Sr(ClO4)2), Sr: 1 (Sr(ClO4)2)
We can see that the equation is not balanced as the chlorine and oxygen atoms are not equal on both sides. We also need to ensure that the number of hydrogen and strontium atoms match.
To balance the equation properly, we need to adjust the coefficients:
HClO4(aq) + Sr(OH)2 → 2H2O + Sr(ClO4)2
1HClO4(aq) + 1Sr(OH)2 → 2H2O + 1Sr(ClO4)2
So, the balanced equation is:
HClO4(aq) + Sr(OH)2 → 2H2O + Sr(ClO4)2
Overall, your second equation was balanced correctly. However, your first equation was not initially balanced but could be corrected by adjusting the coefficients as shown above.
