BALANCE THIS CHEMICAL EQUATION PLS, help:)

Chemistry
1 answer:
Likurg_2 [28]3 years ago
8 0

Answer:

<em>4C₈H₄OH +  35O₂  →  32CO₂   +   10H₂O  </em>

Explanation:

The unbalanced reaction expression is given as:

     

         C₈H₄OH +  O₂  →  CO₂   +   H₂O  

To solve this problem, we use a mathematical approach.

     aC₈H₄OH +  bO₂  →  cCO₂   +   dH₂O

Conserving C: 8a  = c

                    H:  5a  = 2d

                    O: a + 2b  = 2c + d

Let a  = 1, c  = 8, d  = \frac{5}{2}  , b  = 35

   <em>4C₈H₄OH +  35O₂  →  32CO₂   +   10H₂O  </em>

The pH of a Ba(OH) 2 solution is 10.00. What is the H+ ion concentration of this solution?
I am Lyosha [343]

Answer:

Option D. 1×10¯¹⁰ M

Explanation:

From the question given above, the following data were obtained:

pH = 10

Hydrogen ion concentration, [H+] =?

The hydrogen ion concentration, [H+] of the Ba(OH)2 solution can be obtained as follow:

pH = – Log [H+]

pH = 10

10 = – Log [H+]

Divide both side by – 1

– 10 = Log [H+]

Take the antilog of – 10

[H+] = antilog (– 10)

[H+] = 1×10¯¹⁰ M

Therefore, the hydrogen ion concentration, [H+] of the Ba(OH)2 solution is 1×10¯¹⁰ M
