Flame test would be useful for detecting metal ions because each metal ion has its own properties, and when there are many metal ions we can distinguish each metal ion by using or performing flame test.
As in flame test we can distinguish metal ions by there different colors of flames and the color of flames also depends on the temperature factor. And also not all metal ions gives colored flames so sometimes we failed to detect metal ions that are present in a mixture and if there is a very small quantity of metal ions are in a mixture, that is also a problem to detect that.

Answer and explanation;

Metal ions change the color of a flame when they are heated in it. Different metal ions give different colors to the flame. Therefore, flame tests can be used to identify the presence of a particular metal in a sample.

In a flame test, different metal give of different wavelengths of light, some of which we can see, visible light from most metals i.e. Cu, Lit and K. Other metals give off light which we can't see, i.e. Mg. However, if two or more metals present gave more than one color of visible light, it would be hard to distinguish between them to find individual metals and may take several colors as one color, and therefore take several metals as one different metal.

How much H2O is produced when 20000 g of C2H2 burns completely? Answer in units of g.
IgorC [24]

Answer:

Explanation:

H  = 1

C = 12

O = 16

Acetylene, HC≡CH = 2+24 = 26

H2O = 2 + 16 = 18

In XS oxygen, one HC≡CH yields one H2O

26 g HC≡CH  ==> 18 g H2O

2000 g HC≡CH ==> 2000*18/26 g H2O =  1384.6154 g H2O

Explain at least one observation you can make about the political borders and the language borders shown on the maps.
bazaltina [42]

Answer:

A boundary is a real or imaginary line that separates two things. In geography, boundaries separate different regions of the Earth.The most obvious type of boundary is a physical boundary. A physical boundary is a naturally occurring barrier between two areas. Rivers, mountain ranges, oceans, and deserts can all serve as physical boundaries. Many times, political boundaries between countries or states form along physical boundaries. For example, the boundary between France and Spain follows the peaks of the Pyrenees Mountains, while the Alps separate France from Italy.

The Strait of Gibraltar is the boundary between southwestern Europe and northwestern Africa. This narrow waterway between the Atlantic Ocean and the Mediterranean Sea is an important political, economic, and social boundary between the continents.

Rivers are common boundaries between nations, states, and smaller political units such as counties. The Rio Grande forms a large part of the boundary between Mexico and the United States. The Mississippi Riveris the defining boundary between many of the states it winds through, including Iowa and Illinois, Arkansas and Tennessee, and Louisiana and Mississippi.
