Estequiometria de las reacciones

La estequiometría es una rama de la química que se enfoca en las proporciones cuantitativas de los elementos en las reacciones químicas, determinando las relaciones de masa y la cantidad de átomos involucrados.

Rivers have always been essential for human life and settlement. A source for drinking, the source of food, and a way to transfer goods from one place to another. They are essential in the environment of rainforest and wetlands.

The Yangtze holds the title of Asia’s longest river. The Yangtze has a momentous place in China’s history and culture, providing some of the country’s most fertile land as well as some of its most artistically inspiring scenery.

Where the Mekong river runs, the land is incredibly verdant shaping one of the richest areas of biodiversity on the planet. Thousands of species call its shores and waters home. Long an essential trade route the Mekong passes through, or close to, some of the region’s most important cities, including Vientiane, Phnom Penh and Saigon.

Metodo algebraico

The Mekong is a trans-boundary river in Southeast Asia. Its estimated length is 4,350 km.

From the Tibetan Plateau, the river runs through China's Yunnan Province, Myanmar, Laos, Thailand, Cambodia, and Vietnam.
The Mekong rises as the Za Qu and soon becomes known as the Lancang (Lantsang) in the 'Three Rivers Source Area' on the Tibetan Plateau in the Sanjiangyuan National Nature Reserve. It approaches and empties into the sea through the Mekong Delta. Tributaries: Nam Khan, Tha, Nam Ou, Mun, Tonle Sap, Kok, Ruak.

The Yangtze or Yangzi is the longest river in Asia and the longest in the world to flow entirely within one country (Qinghai, Tibet, Yunnan, Sichuan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu, Shanghai provinces). It rises in the northern part of the Tibetan Plateau and flows 6,300 km in a generally easterly direction to the East China Sea.

Tributaries: Yalong, Min, Tuo, Jialing, Han, Wu, Yuan, Zi, Xiang, Gan, Huangpu.
In mid-2014, the Chinese government announced it was building a multi-tier transport network, comprising railways, roads, and airports, to create a new economic belt alongside the river.

Definición

The Volga is the longest river in Europe. The waters of the Volga are used to irrigate the steppe regions of southern Russia. Because of its importance in the country, the Volga has mythological status in Russia, and many iconic sites are found along its banks

The Danube is the second-longest river in Europe. Travelers can experience many of the river's sights by embarking on a cruise along its waterways. Danube River Cruises, which are offered by Viking Cruises, typically stop in Cologne, Budapest, Nuremberg, Belgrade and Krems. Following the river is a way to experience several Eastern European cities in one trip. Famous monuments, such as the Hungarian Parliament, have been erected on its coast.

The Volga is the longest river in Europe with a catchment area of 1,350,000 square km.
Eleven of the twenty largest cities of Russia, including the capital, Moscow, are located in the Volga's drainage basin. Rising in the Valdai Hills 225 meters above sea level northwest of Moscow and about 320 km southeast of Saint Petersburg, the Volga heads east past Lake Sterzh, Tver, Dubna, Rybinsk, Yaroslavl, Nizhny Novgorod, and Kazan. From there it turns south, flows past Ulyanovsk, Tolyatti, Samara, Saratov, and Volgograd, and discharges into the Caspian Sea.
Tributaries: Kama, Oka, Vetluga, and Sura. The Volga Delta has a length of about 160 kilometers and includes as many as 500 channels and smaller rivers.

Conceptos importantes

There are four major rivers in Africa: the Nile, the Zambezi, the Congo, and the Niger. The Nile is one of the longest rivers in the world.

The Zambezi's most noted feature is Victoria Falls. Other notable falls include the Chavuma Falls at the border between Zambia and Angola, and Ngonye Falls, near Sioma in Western Zambia.

The Nile, which is about 6,650 km long, covers eleven countries: Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt.

It has two major tributaries, the White Nile and the Blue Nile. The White Nile is the headwaters and primary stream of the Nile. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. The two rivers meet just north of the Sudanese capital of Khartoum.
The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta and flows into the Mediterranean Sea.

Unidad de medida

The Nile flows through 7 countries and 3 republics from Africa. Type them in.

In the 18th century, the river was the primary western boundary of the young United States, and since the country's expansion westward, the Mississippi River has been widely considered a convenient dividing line between the Eastern, Southern, Midwestern United States, and the Western United States.

South America

Amazon River, the greatest river of South America and the largest drainage system in the world in terms of the volume of its flow and the area of its basin.

Its source is Lake Itasca in northern Minnesota and it flows generally south for 2,320 miles (3,730 km) to the Mississippi River Delta in the Gulf of Mexico.

The main stem is entirely within the United States. Tributaries - St. Croix River, Wisconsin River, Rock River, Illinois River, Kaskaskia River, Ohio River, Minnesota River, Des Moines River, Missouri River, White River, Arkansas River.

The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana.
