What was the world's first village
Identifying the world's first village is challenging because the transition from nomadic to settled life occurred gradually across multiple regions over thousands of years during the Neolithic Revolution (roughly 10,000-8,000 BCE). One of the earliest known permanent settlements is Jericho in the West Bank, with archaeological evidence showing continuous occupation beginning around 9000 BCE with structures, storage facilities, and defensive towers indicating settled community life.

Is CaO H2O → Ca(OH)2 balanced
Yes, the equation CaO + H2O → Ca(OH)2 is already balanced as written. Each side contains one calcium atom, two hydrogen atoms, and two oxygen atoms, satisfying the law of conservation of mass. This represents the slaking of quicklime, where calcium oxide reacts with water to produce calcium hydroxide in a highly exothermic reaction that releases significant heat. In practical applications, this balanced equation is fundamental to understanding how quicklime behaves in constructio

Which is the second city in the world
The concept of "second city" typically refers not to the historical second city ever established, but to a country's second-most important city after its capital or primary metropolis—a major urban center that serves as an economic, cultural, or political alternative to the dominant city. In various global contexts, "second city" can mean different things: in the United Kingdom, Birmingham is traditionally called the "second city" after London; in the United States, Chicago historically

Who built the first city on Earth
No single individual built the first city on Earth—cities emerged gradually through collective human effort as agricultural surpluses allowed permanent settlements to grow beyond villages into complex urban centers. The earliest cities developed in Mesopotamia (modern Iraq), particularly Uruk around 4000-3000 BCE, through accumulated generations of building, expansion, and social organization by ancient Sumerian populations. These proto-urban developments involved contributions from tho
