Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms, unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell. Atoms attain noble gas configuration by gaining or losing electrons in order to satisfy the role of an octet.
Atoms want a full outer shell because it completes all the gaps in the outside. With no gaps, other electrons don't want to fit into those spaces. For example, a noble gas like Neon has a full outer shell. It doesn't react with other chemicals because the electrons from other chemicals can't fall in anywhere. Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms, unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell.

Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions. In double replacement reactions, the positive ions exchange negative ion partners. A double replacement reaction is represented by the general equation.
AB + CD → AD + CB
Fe2O3 + 6HCl → 2FeCl3 + 3H2O

The French revolution broke out due to various social, economic, intellectual and political factors.
The then King of France, Louis XVI was inefficient and an autocrat.
The Social society of French was inequally divided.
The first and second classes were comprised of the Clergy and Nobility which were the priviliged classes exempted from all kind of state taxes.
The third estate or the third class was comprised of the majority of the population which were the unpriviliged classes and had to pay all the state taxes.
The population of France rose greatly during 1780's leading to food crisis. The price of bread rose highly during that time.
The treasury of France got empty due to continuous war and the luxurious living ways of the King.
After the assembly on 5 May, 1789, the members of the third estate became more agitated about their rights in the administration.
On July 14, 1789 the agitated crowd stormed and destroyed the bastille, the fortress prison, leading to outbreak of the French Revolution.

The Bretton Woods Agreement was finalised in July 1944 at Bretton Woods in New Hampshire, USA. It established the International Monetary Fund and the World Bank to preserve global economic stability and full employment in the industrial world. These institutions also dealt with external surpluses and deficits of member nations, and financed post-war reconstructions.

One of the main reason why the copper vessels lose their shine when exposed to air is due to the passivization.
When copper forms as protective layer of oxidation on the surface for preventing the further deterioration then material would be around the normal condition.
At the surface of vessel, Copper atoms react with the Oxygen atoms in the air forming copper-oxide.

Electric potential at a point in an Electric field (for instance, let's take it as uniform) is the amount of work done in moving a unit positive charge from infinity to that point against electric forces. (attraction or repulsion)
whereas Electric potential difference between two points in an Electric field is defined as the amount of work done in moving unit positive charge from one point to another point against the electric force.
In other words, Potential difference is simply the difference of scalar potentials between two points or anything you consider.

Statistics is a form of mathematical analysis that uses quantified models, representations and synopses for a given set of experimental data or real-life studies. Statistics studies methodologies to gather, review, analyze and draw conclusions from data. The two main branches of statistics are descriptive statistics and inferential statistics. Both of these are employed in scientific analysis of data and both are equally important for the student of statistics.

Formula of curved surface area of cone = πrl
Where r is radius and l is slant height
Since we are given slant height is 10 cm and base radius is 7cm
So, Curved surface area of cone = 3.14 × 25 ×7
Hence the curved surface area of cone is 549.5 cm square.

Angstrom (Å), unit of length used chiefly in measuring wavelengths of light, equal to 10−10 metre, or 0.1 nanometer. One angstrom is equal to 10−10 m (one ten-billionth of a meter or 0.1 nanometers). Although the unit is recognized world-wide, it is not an International System (SI) or metric unit. It is named for the 19th-century Swedish physicist Anders Jonas Ångström.

A climate is that average weather in an exceeding place over a few years. Whereas the weather would be an amendment in the matter of mere hours, the environment takes a whole bunch viz. thousands of years to alter. However, it is dynamic and rising at an alarming rate over the past few years.
