A chemical bond results from the mutual attraction of the nuclei for atoms and electrons.

Explanation:

Each atom tends to have an energy between the nuclei and electrons to keep it stable. So, there will be mutual attraction of the nuclei of atom and of electrons in the innermost shell to the outermost shell. And, this kind of mutual attraction can also be termed as chemical bond or binding energy.

So, depending upon the strength of mutual attraction, the nature of the element can be determined as well as its nature of reactivity can be analysed. So, results as a chemical bond from the mutual attractions of nuclei for atoms and electrons.

A. What is the basic building block of matter?

Nikitich [7]

Answer:

a. atoms are the basic building blocks of matter. The atom is made of electrons and protons. It contains the chemical identity of an element.

b. Three types of particles that make up an atom are:

electrons - these are negatively charged particles and lightest constituents of an atom.

protons are positively charges and is 1873 times heavier than an electron.

Neutrons are neutral particles having mass equivalent to mass of proton.

Protons and neutrons exist in the center of an atom in nucleus and electrons revolve around the nucleus.

c. An atom is a neutral entity where as an ion is charged. An ion has excess of electrons or lacks electrons due to which it has negative or positive charge. An atom has an equal number of electrons and protons.

d. In a negative ion, the number electrons is greater than number of protons. The atom when gains electrons becomes negative ion.

e. John Dalton proposed Solid sphere model in which tiny invisible particles constitute matter. These invisible particles are atoms and these are indivisible.

True or False: Inertia is the property that every material object has that causes objects to resist changes in its state of moti

goldfiish [28.3K]

That is True because if it resists it means to not do it and if it is motion, that means that it is resisting movement and that is what inertia is.

The scientific definition for inertia is: "a tendency to do nothing or to remain unchanged"
Glad to help. :)

The pressure at the button of a glass filled with water

-Dominant- [34]

Answer: Plz mark me brainlest.

The pressure in the bottom of the glass is defined as P= (pv)g/A.

V is the Volume.
A is the Area.
G is the acceleration due to gravity.

P is the density.

A 0.43 m long and 0.43 m wide loop is moved at a constant velocity of 0.15 m/s into a perpendicular constant magnetic field of 0

olya-2409 [2.1K]

Answer:

The magnitude of the induced voltage in the loop is 20 mV.

Explanation:

given;

length of loop, L = 0.43 m

width of loop,w = 0.43 m

velocity of moved loop, v = 0.15m/s

magnetic field strength,B = 0.31 T

To determine the magnitude of the induced voltage in the loop, we apply Faraday's law;

magnitude induced E.M.F = BLv

magnitude induced E.M.F = 0.31 x 0.43 x 0.15 = 0.02 V = 20 mV

Therefore, the magnitude of the induced voltage in the loop is 20 mV.

What mRNA sequence would result from the following DNA sequence?

Nezavi [6.7K]

Answer:

UAC CUG AGG AUC

Explanation:

The mRNA sequence from ATG GAC TCC TAG DNA sequence would be UAC CUG AGG AUC.

According to Chargaff's base pairing rule, the purine bases always pair with pyrimidine bases. Specifically, Adenine base must pair with Thymine base while Guanine base must pair with Cytosine base. In RNA, Thymine base is replaced with Uracil base.

Hence:

ATG GAC TCC TAG will pair with

UAC CUG AGG AUC
