An element from group 2 will form ionic bonds with - 1

Answers

Answer 1
Answer:

An element from group 2 will form ionic bonds with a nonmetal group 13-17, therefore the correct answer is option C.

What is an ionic bond?

When electrons are moved from the atoms of one element to the atoms of another, creating positive and negative ions, ionic bonds are created. Ionic bonds are only between metals and non-metals occur. There can not be the formation of the ionic bond between two metals.

These ionic bonds are also known as electrovalent bonds as they are formed because of the transfer of the electrons.

There must be one electropositive element that can release electrons which is metal as metals have extra electrons in their valence shell.

There must be one electronegative element involved during the formation of the ionic bond, which is a nonmetal as nonmetals have few electrons left to complete their outermost shell.

As given in the problem element of group 2 are metals and will form ionic bonds with the nonmetal elements of the group 13-17.

Thus, the correct answer is option C.

What is an example of a light mediem wave.

Answers

Speed of light is an example of a light medium wave.

Most famous Michelson-Morley (1887) demonstrated that light travels at the same speed regardless  of whether it was measured in the direction of the Earth's motion or at right angles to it. When the light travels through a vacuum: It moves from medium to medium (example: air to glass) speed can change depending of the new medium's index of refraction and the "bending" of light is essentially how lenses work.
Hey there

There are 4 hydrogens on the right side (2\mathrm H_2=4\mathrm H), and 2 hydrogens on the left per molecule of \mathrm H_2. To get the same number of hydrogens on both sides, the coefficient should be 2.

(Then the number of oxygens will be consistent, since 2\mathrm H_2\mathrm O contributes 2 oxygens, and so does \mathrm O_2.)

if i cut a body in half, after the application of heat to a body what will be the resultant temperature of the two halves

Answers

The temperature of both the halves of the body remain same and thus the body  remain in thermal equilibrium.

Both the parts of the body even after being in contact with each other will not transfer heat and thus maintain equal temperature and the resultant of the two will be zero.


The resultant temperature of the two halves will be same as the temperature of the body before cutting them into two.

Explanation:

As the body of heated between cutting it into two halves, so the temperature of the body will be same even after cutting them into two halves. This can be confirmed from zeroth law of thermodynamics.

As the heat is stored in the form of temperature of the body when heated. The after cutting it into two halves, the temperature will be remained same as temperature does not depend on the mass of the object once the heating process is completed.

The temperature would have varied if the two halves were heated again but in this case after heat process is completed, the body is divided. This leads to no change in temperature of the two halves.
