If you have a pH of 3.35, what is the hydrogen ion concentration of the solution?
melamori03 [73]

Answer: 4.46 x 10^-4M

Explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

On the pH scale, readings are from 1 to 14.

- pH values less than 7 are regarded as acidic. So, the solution with pH 3.35 is said to be acidic, and will produce hydrogen ions.

3.35 = -log(H+)

(H+) = Antilog (-3.35)

(H+) = 0.000446M

Place (H+) in standard form

(H+) = 4.46 x 10^-4M

Thus, the concentration of hydrogen ion in the solution with pH 3.35 is 4.46 x 10^-4M

In a plant, 1500kg of nitrogen oxide is consumed per day to produce 1,500 kg of nitrogen per day. What is the prevent yield?
slavikrds [6]

Answer:

65.21 percent

Explanation:

We are to find the percentage yield

We have this equation,

2no+o2 -->2no2

Such that 1500 kilograms/30grams

= Mno2/46

=1500/30 = mno2/46

We cross multiply from here

1500x46 = 30xMnO2

69000 = 30Mno2

69000/30 = MnO2

2300 = Mno2

The percentage yield would be

1500/2300 *100

= 0.6521 x 100

= 65.21%
