Answer : The correct option is, B) They are both acids.

Explanation :

Acids : Acids are those which have higher concentration of hydrogen ion. The pH range of an acid is 0 to 6.9.

Base : Base are those which have higher concentration of hydroxide ion. The pH range of base is 7.1 to 14.

In coca cola, there are three acids present which are citric acid, carbonic acid and phosphoric acid.

In tomato juice, only citric acid is present.

The pH of both coca cola and tomato juice is less than 7 that means both are acidic solution.

Electron orbitals or shells are also called and abbreviated as?

Answer:

An Orbital is best described as the volume of space in which electrons are most often found

Explanation:

As we know atom consists of sub-particles commonly known as protons, neutrons and electrons. The outer space around the nucleus where the probability of finding electrons is maximum is known as orbital. As the electrons are not precisely ordered around the nucleus hence it is not easy to tell the exact position of an electron.

Hence, four quantum numbers are used to locate the position of electrons around the nucleus.

i) Principle Quantum Number:

This number explains the main energy level which tend to increase in energy as the distance of electrons from nucleus are increased. Principle Quantum Numbers are integer number ranging from one to infinity. Hence, increase in this quantum number results in increase of the size of orbital.

ii) Azimuthal Quantum Number:

This Quantum Number explains the direction of particular orbital in 3-dimensional space. Also it is responsible for the shape of an orbital.

iii) Magnetic Quantum Number:

This Quantum Number also tells the direction of orbital in 3D space with respect to x, y and z axis.

iv) Spin Quantum Number:

This Quantum Number tells about the spin direction of an electron about its axis which may be clockwise or anticlockwise.

at atmoshperic pressure, a balloon contains 2.00L of nitrogen of gas. How would the volume change if the Kelvin temperature were

Nataly [62]

<u>Answer:</u> The percent change in volume will be 25 %

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=2L\\T_1=T_1\\V_2=?\\T_2=75\% \text{ of }T_1=0.75\times T_1$

Putting values in above equation, we get:

$\frac{2L}{T_1}=\frac{V_2}{0.75\times T_1}\\\\V_2=\frac{2\times 0.75\times T_1}{T_1}=1.5L$

Percent change of volume = $\frac{\text{Change in volume}}{\text{Initial volume}}\times 100$

Percent change of volume = $\frac{(2-1.5)}{2}\times 100=25\%$

Hence, the percent change in volume will be 25 %
