Explanation:
a) 4P + 3O2 --> 2P2O3
b) The chemical reaction above limits the number of molecules of P2O3 produced for every 4 atoms of P.
The statement that describes NASA's Chandra X-ray Observatory is a space telescope.
Explanation:
Usually telescopes are used by the astronomer's to find objects which are placed in far places.
But Chandra X-ray observatory is the NASA's space telescope.
This telescope is used to find and discover advanced X-rays which are produced in the space due to explosion of stars, clusters and the matter around black hole in the hot regions.
Therefore, this NASA's Chandra X-ray Observatory is a space telescope.
The amount of potassium chloride in the solution is represented as 33.49 w/V. The metal halide salt potassium chloride (KCl, often known as potassium salt) is made up of both potassium and chlorine.
It has a vitreous crystal look and is odourless or colourless. The material easily dissolves in water, and the flavour of its solutions is similar to salt. In a homogenous mixture of two or more components, a solution is defined as having particles less than one nanometer in size. Solutions come in many forms, such as sugar and salt solutions, soda water, etc. potassium chloride and metals combine to form metal halides. Others are covalently bound, while others, like sodium chloride, are ionic.
The amount of KCL in 100 ml is 34.7/103.61*100 = 33.49gm.
