To get the net chemical equation, you should write out the
two equations and then add the elements or compounds on each side. And then cancel
ones that are on each side.
But first, you'll need to multiply the first equation by 6.
6CaC2(s) + 12H2O(g) + 6C2H2(g) + 3CO2(g) + 4H2O(g) = 6C2H2(g) + 6CaOH2(s) +
5CH2CHCO2H(g)
6CaC2(s) + 12H2O(g) + 3CO2(g) + 4H2O(g) = 6CaOH2(s) + 5CH2CHCO2H(g)
6CaC2(s) + 16H2O(g) + 3CO2(g) = 6CaOH2(s) + 5CH2CHCO2H(g) is the net chemical equation.
The Huang He, or Yellow river was very important in Ancient Chinese society. It's called the yellow river because of the huge amount of silt inside of it flowing down. Because of this, the soil around it was very fertile, and this was great for rice farmers.
The Indus River Valley civilization relied on the Indus River because it provides a source of water, travel, and irrigation for crops, as well as very fertile soil.
Hope this helps
Answer:
Civilizations developed around rivers because their waters provided places to hunt and fish. Also, as the rivers flooded, the lands around them became fertile. This allowed them to support farming. This is especially true of the Nile River, which flooded the same time each year.
Explanation:
Answer:
The statement is false, as the region of present-day southern Iraq was part of the Fertile Crescent.
Explanation:
The Fertile Crescent is a region in the Middle East, south of the mountains of Turkey and Iran. It mainly covers the fertile areas of Iraq, Syria, Lebanon, Israel and Jordan, as well as parts of southeastern Turkey and southwestern Iran. The area is home to the great Euphrates and Tigris Mesopotamian streams, as well as the Syrian Orontes and the Levant Jordan. The Nile valley in Egypt is also often considered to be part of the region.
The Fertile Crescent takes its name from its semi-resembling shape and its good cultivation conditions, which allowed agriculture to develop in the area between 11000 and 8000 BC. The area is home to most of today's most important crops and livestock.
In the prehistoric and early history, the region developed the first major cities and early centers of cultivation as agriculture enabled it to support large numbers of people.
What war? I doubt we will be having another war. But if we do then we got to get ready for it.
