Answer:
1) magnesium chloride
2) b) The copper is getting oxidized from Cu+ to Cu2+ and turns blue.
Explanation:
The work published by David N. Frick, Sukalyani Banik, and Ryan S. Rypma in J Mol Biol. 2007 Jan 26; 365(4): 1017–1032 clearly shows that divalent metal ions of group 2 such as Mg^2+ play an important role in ATP hydrolysis. Addition of EDTA decreased the rate of hydrolysis of ATP (due to sequestration of the divalent ion of group 2) indicating an active participation of divalent ions in the process.
2) The copper I ion is colourless because it is a d^10 specie. However, when it is oxidized to Cu^2+, a blue colour appears in the solution.
<span>The ionic form of Chlorine is Chloride. Chloride helps maintain the body's fluid balance. It is a component of hydrochloric acid (HCl acid) in your stomach which helps good digestion. It is also an aide to maintain the acid-base balance of your body. Among the choices given, letter C is not a function of chloride. Excess or too much dietary intake of chloride causes hypertension.</span>
A solid that forms and separates from a liquid mixture is a chemical change.
Answer:
Explanation:
Chloride is described as an extended structure because its atoms are arranged following an endless repeating pattern and are of distinct ratio
Crystals and polymers mostly form extended structures as seen in the formation of sodium chloride whereby the ions in the compound are arranged following a repeating pattern. ( i.e. has a giant ionic structure ).
Chloride is a considered an extended structure because in sodium chloride it forms an unending repeated pattern of ions which makes it a perfect example of an extended structure.
Hence we can conclude that Chloride can be described as an extended structure because its atoms are arranged following a repeating pattern and are of distinct ratio.
Answer:
Decomposition or cracking
Explanation:
Decomposition reaction is a chemical change in which a single compound is broken down into two or more simpler products.
For example;
A → B + C
The driving force of such reaction is the high positive heat of formation of the compound which indicates that they are highly unstable.
Some stable compounds also decompose when subjected to high temperature and pressure.
