What is metallic bonding , properties and everything about it?
Elodia [21]
Metallic bonding

The particles in a metal are held together by metallic bonds.

High melting and boiling points

Metallic bonds are strong and a lot of energy is needed to break them. This is why metals have high melting points and boiling points.

Conducting electricity

Metals contain electrons that are free to move in the metal structure, carrying charge from place to place and allowing metals to conduct electricity well.

Metallic bonding - Higher tier

Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons.

Write a chemical equation depicting what happens to the sugar in water.
zysi [14]
Assuming that you mean table sugar (sucrose), then at room temperature and without any catalyst, there is no reaction. 

However if you elevate and hold the temperature of the aqueous solution at 50 to 60 °C (especially in the presence of a suitable catalyst, like mineral acid) the sucrose dimer will split into glucose and fructose. This is called hydrolysis and the resulting solution is called an invert sugar solution. 

The reaction could be written as: 

C12H22O11 (sucrose) + H2O (water) → C6H12O6 (glucose) + C6H12O6 (fructose) 

or 

C12H22O11 (aq) + H2O (l) → C6H12O6 (aq) + C6H12O6 (aq) 

Notice that both of the produced sugars have the same empirical formula. Check with your instructor or in your textbook to see if more exact formulas are needed.

if 5.01 moles of ti are mixed with 7.86 moles of cl2 and 2.47 moles of ticl4 are formed, what is the percent yield of this react
ipn [44]

Titanium is also utilized in the construction of portable computer housings and medical implants. Despite being the ninth most prevalent element in the crust of the Earth, titanium is relatively challenging to extract from its ores. Titanium-containing oxide minerals react with solid carbon and chlorine gas to produce titanium tetrachloride and carbrabon dioxide in the first step of the extraction process.

therefore,

5.01+7.86=12.87

12.87/2.47=19.1%

Yeild Percentage is 19.1%

Minerals are naturally occurring inorganic elements or compounds with an organized internal structure, a distinctive chemical composition, crystal shape, and physical characteristics. The yield percentage is 19.1%. Quartz, feldspar, mica, amphibole, olivine, titanium, and calcite are examples of common minerals.
