Verified answer
Answer:
1] Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
2] A yellow flame indicates incomplete combustion, which means you are wasting gas and money, also it may serious safety hazard. With hydrocarbon flames, such as gas, the amount of oxygen supplied with the gas determines the rate of combustion, flame colour, and temperature.
3] Iron does not react with cold water as well as hot water but with steam, the red-hot iron reacts to give its respective oxide and hydrogen gas.
Explanation:
Answer:
Q.1 Good electrical conductors and heat conductors.
Malleable - can be beaten into thin sheets.
Q.2 A yellow flame indicates incomplete combustion, which means you are wasting gas and money, also it may serious safety hazard. With hydrocarbon flames, such as gas, the amount of oxygen supplied with the gas determines the rate of combustion, flame colour, and temperature.
Q.3 Iron does not react with cold water as well as hot water but with steam, the red-hot iron reacts to give its respective oxide and hydrogen gas(red hot iron)
