Answer: -
Rimmed steel does not contain nickel.
Explanation: -
Rimmed steel is a deoxidised low carbon steel. Deoxidation leads to formation of rims in the iron.
Carbon, sulfur and phosphorus is present in rimmed steel. The concentrations of these vary from the outer rim to the inner rim. It is not as tough as other steel.
Hence it is primarily used for products where a lot of bending is required. Thus Rimmed steel does not contain nickel.
Mass percentage = (mass of Al)/(Total mass) * 100
= (26.98) / (26.98 + 3 * (1.0079 + 16)) * 100
= 34.59%
In Silver, the 4d orbitals will be completely filled. That
implies that it does not have two electrons in the 5s orbital. The electronic
configuration of Silver is :
Ag (47) = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^1
4d^10
Answer
B,C,D,E
Explanation:
Hydrogen bonds in water forms a tetrahedral ( four sided structure) and not a six sided structure.
The hydrogen bonds are needed to be broken first when heat is applied to change from one state to another.It makes room for more heat to be applied than the required amount which signifies a higher latent heat of melting or vaporization and also a higher heat capacity .
