Subduction zones are where the seafloor is forced under continental plates
Area = L • W
Area = Length (multiplied) by the width
So if you had a rectangle that had a length of 4 and a width of 7 you would do 4 • 7 = 28 so the area of that rectangle would be 28.
Answer:
Explanation:
The chlorine is present in group 17. It has seven valance electrons. It accept one electron to complete the octet and show -1 charge and from anion.
Cl⁻
Sodium is present in group one. It alkali metal. It loses one valance electron and show +1 charge. It form sodium cation.
Na⁺
Magnesium is present in group two. It loses its two valance electrons and show +2 charge. It form magnesium cation.
Mg⁺²
Oxygen is present in group 16. It has six valance electrons. It require two electrons to complete the octet and show -2 charge.
O⁻²
Aluminium is present in group 13. it has three valance electrons. It loses its three valance electrons and show +3 oxidation state
Al⁺³ (most common)
others = Al⁺¹, Al⁺²
Iron is present on group eight.
Fe⁺² , Fe⁺³ (most common)
others = Fe⁺⁴, Fe⁺⁵
Copper is present in group eleven.

Answer:
C10H22
Explanation:
C6H6 is the molecular formula for Benzene. Benzene is an aromatic hydrocarbon which is obtained from the destructive distillation of coal. Benzene is a colourless volatile liquid with a sweet smell. Its vapor is highly toxic and mildly carcinogenic. It is highly inflammable. Benzene is nonpolar which is insoluble in water. Since benzene is insoluble in water , it will take an insoluble compound to be soluble in benzene since "like dissolves like".
From the options given:
C10H22 which is the molecular formula for Decane would be the most soluble in C6H6. This is because Decane is an alkanes which is an aliphatic hydrocarbon and their physical properties increases with increasing molar mass ( i.e melting points, boiling points , density, polarity) etc. The first mfour member of the family are gases. non-polar liquid starts with th fifth member of the family which is pentane and from hexadecane onwards the members are solids at room temperature. Thus, decane is a non-polar hydrocarbon which is insoluble in water but soluble in benzene
