chemical properties of metal when reacts with oxygen and water
Answers
Answer:
Some main physical properties of metals are;
•The have lustreand a metallic appearance.
•They are usually in the form of a solid at room temperature.
•They are very good conductors of electricity and heat.
•Metals are malleable and ductile.
•They mostly have a very high melting point.
Answer:REACTION WITH BASE - DEFINITION
concept - metal + base ------> Hydrogen gas
Metals give hydrogen gas when they react with a base. Reaction of non-metals with bases are complex.
REACTIONS WITH ACIDS - DEFINITION
concept - metal + acid ------> Hydrogen gas
Metals give hydrogen gas when they react with dilute acid. Generally, non-metals do not react with dilute acid.
CHEMICAL PROPERTIES - DEFINITION
Metals are very reactive. Metals tend to lose electrons easily and form positively charged ions. Therefore metals are called electropositive elements. Non-metals accept electrons readily because they have high electronegativities.
REACTION OF NON-METAL WITH WATER - DEFINITION
Metals react with water to form hydroxides , generally non-metal do not react with water.
