Why are there many butt limited combinations of elements that make compounds

Physics

Alinara [238K]4 years ago

<h2>Answer:</h2>

We have limited combinations of elements to make compounds because most of the compounds are not stable due to different chemical properties of elements.

<h2>Explanation:</h2>

Elements combine to form compounds but not all of the elements combine in the same way. The individual properties of each element must be taken into account before combining them.

The most common types of compounds are metallic compounds, ionic compounds, and covalent compounds. All compounds made in the laboratory are not stable and the same phenomenon occurs in nature as well. Elements that have more tendency to react with other elements are far less than the total number of elements in the periodic table.

Every element tries to make a bond with another element that fulfill the requirements of both of them. For example if an element needs to lose its one electron will always try to make compound with another element that will have the tendency to gain one electron. They will not make bond with other random element so in this way  the combinations of elements that make compounds becomes limited.

A uniform 1.0-N meter stick is suspended horizontally by vertical strings attached at each end. A 2.0-N weight is suspended from
fgiga [73]

Answer:

3.5 N

Explanation:

Let the 0-cm end be the moment point. We know that for the system to be balanced, the total moment about this point must be 0. Let's calculate the moment at each point, in order from 0 to 100cm

- Tension of the string attached at the 0cm end is 0 as moment arm is 0

- 2 N weight suspended from the 10 cm position: 2*10 = 20 Ncm clockwise

- 2 N weight suspended from the 50 cm position: 2*50 = 100 Ncm clockwise

- 1 N stick weight at its center of mass, which is 50 cm position, since the stick is uniform: 1*50 = 50 Ncm clockwise

- 3 N weight suspended from the 60 cm position: 3*60 = 180 Ncm clockwise

- Tension T (N) of the string attached at the 100-cm end: T*100 = 100T Ncm counter-clockwise.

Total Clockwise moment = 20 + 100 + 50 + 180 = 350Ncm

Total counter-clockwise moment = 100T

For this to balance, 100 T = 350

so T = 350 / 100 = 3.5 N

What is the advantage of the SI unit over CGS units?
MatroZZZ [7]

Answer:

The advantage of the SI unit over CGS unit are:

  • S.I has broader base. It has seven base units and two supplementary units.
  • S.I is metric.
  • S.I is coherent.
  • S.I is rational, i.e. it gives one unit for one physical quantity .e g. for energy of any type i.e, mechanical or heat or electrical.There is only one unit Joule(J) but in M.K.S system unit for mechanical energy is joule.

Select the statement that best describes gravity.
ch4aika [34]

Answer:

Gravity is the force of attraction between two objects; it is dependent upon the mass of the objects and the distance between the objects.

Explanation:

Gravity is defined as the force of attraction between two objects. It depends on the masses of objects and the distance between them. The gravitational force between two bodies is given by the universal law of gravitation. According to this law, the force of gravity is :

F=G\dfrac{m_1m_2}{d^2}

Where

G is the universal gravitational constant

m₁ and m₂ are masses of two bodies

d is the distance between two bodies

Hence, the correct statement that describes gravity is (b)
