n chemistry, the pH of a solution is defined by: pH space equals space minus log space left square bracket straight H plus right
slavikrds [6]

Answer:

The correct option is;

pH = 4.1

Step-by-step explanation:

The given information are;

The hydrogen ion [H⁺] concentration in tomato juice = 10 ^{-4.1}

The pH of a solution = -㏒{H⁺] =  -㏒( 10 ^{-4.1}) = -(-4.1) × ㏒(10) = 4.1

The pH of the of the tomato juice = 4.1

The pH is the term used to refer to the acidity of water with the range of pH values ranging from 0 to 14 where pH values of a solution lesser than 7 are considered acidic while pH values above 7 indicate a basic solution.

the number of bacteria in a sample after x days is represented using the equation <img src="https://tex.z-dn.net/?f=b%3D50%2C000
KATRIN_1 [288]
Initial, x = 0, b = 50000

day 1, x = 1, b = 50000 (1.05)^-1

day 2, x = 2, b = 50000 (1.05) =^-2

day 2 / day 1 = 1.05^-2 / 1.05^-1 = 1.05^-1 = 0.952

Which means that the number of bacteria decreased 4.8%

garik1379 [7]

Answer:

Step-by-step explanation:

The decibel level of the sound of a monster truck is

Further explanation:

Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.

In the question it is given that the intensity of the sound of a monster truck is watts per square inch.

The formula which is used to calculate the decibel level of a sound is as follows:

Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .

The value of the threshold intensity of hearing at is watts per square meter.

This implies that the valiue of is watts per square meter.

The intensity of the sound of a monster is given in unit of per square inch.

The relation between per square inch and per square meter is as follows:

So, the intensity of a monster truck is converted into per square meter as follows:

This implies that the value of is watts per square meter.

Now, substitute the value of and in the equation .

The approximated value of the above equation is as follows:

From the above calculation it is concluded that the decibel level of the sound of a monster truck is .
