Why does silicon have a high melting point

Chemistry
1 answer:
Igoryamba3 years ago

If the bonds are held together tightly, as an ionic bond or even a covalent bond, there will need to be a strong force to separate those bonds. This would by why their would be a high melting point. Another reason would be re-activity. <span />

When aqueous solutions of sodium chloride and silver (I) acetate combine, what are the products?
lesya692 [45]

Answer: The products are sodium acetate (CH_3COONa) and solid silver chloride (AgCl)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The reaction of  aqueous solutions of sodium chloride and silver (I) acetate is :

NaCl(aq)+CH_3COOAg(aq)\rightarrow CH_3COONa(aq)+AgCl(s)

Thus the products are aqueous sodium acetate (CH_3COONa) and solid silver chloride (AgCl)

I am a metal which can be drawn into thin wires
Gwar [14]

Answer:

Silver and copper

Explanation:

Siliver

Electrical conductivity=62000000(s/m)

Boiling point=2162

Melting point=961.78

Phase=solid

Copper

Electrical conductivity=59000000(s/m)

Boiling point =2927

Melting point=1084.62

Phase=soild

Metals like gold, silver and copper are drawn into thin wire and are used in an electric circuit because of their high electrical conductivity

Mostly Siliver and copper are used since using gold is much expensive.

The table below lists norm al and abnormal events. Explain why some events would never happen normally.
vlada-n [284]
Beacause of lack of force in all three scenarios.
In scenario one there’s two forces acting in the bottle atmospheric pressure and gravity.Gravity keeps the ball at the lowest pointwithout force resisting it.
Umber two there’s no other force greater than gravity that would cause movement to the apple..
And number three there are isn’t any force acting in the rubber band greater than the elastic force to make it stretch
Hope this helps and mark as brainliest if you thought it was most helpful :)
