Answer:

Ionic or electrovalent bond

Explanation:

The electronegativity of an atom determines to what extent an atom would attract an electron towards it. So, they can form combine.

The nature of chemical bonding depends upon the difference between the electronegativity of the combining atoms.

When the electronegativity difference is

< 0.4 - forms non-polar covalent bonds

between 0.4 and 1.7 - polar covalent bonds

> 1.7 - ionic bond

Hence, when there is a large difference between the electronegativity of atoms, it forms ionic bonds.

B. instantaneous speed

The speedometer of a car show instantaneous speed.
Instantaneous speed is the motion rate of a car (in this example) at a particular moment or instant in time. It can be calculated by dividing a portion or a part of the total distance (of the trip) by time traveled.

Which of the following statements is false?

vladimir1956 [14]

An excited atom can return to its ground state by absorbing electromagnetic radiation is false about the electromagnetic radiation.

Option B

<u>Explanation</u>:

In the scope of modern quantum theory, the term Electromagnetic radiation is identified as the movement of photons through space. Almost all the sources of energy that we utilize today such as coal, oil, etc are a product of electromagnetic radiation which was absorbed from the sun millions of years ago.

Various properties of electromagnetic radiations are a directly proportional relationship between the energy and the frequency, Inverse proportionality between frequency and the wavelength, etc. Hence, we can conclude that an "excited atom" can never return to its ground state by assimilating electromagnetic radiation and the 2nd statement is false.

As stream discharge increases ________. only velocity increases velocity, width, and depth increase velocity, width, and depth d

nignag [31]

As stream discharge increases, only velocity increases.

<h3>What is discharge?</h3>

The discharge or volume flow rate is defined as the product of the velocity of the fluid and the area of cross- section of the pipe or tube.

Discharge Q = Area A x Velocity V

Q = AV

The discharge is directly proportional to the velocity of the fluid. When discharge increases, velocity is the only physical quantity that can be changed.

Thus, As stream discharge increases, only velocity increases.
