Its tetrahedral since there's four chlorine molecules around carbon
Answer:
1. 0.82 gram of Ag+
2. 4.79 g of Ag₂O₃S
Explanation:
From the given information:
Total amount of Ag₂O₃S = 2.24 grams
Atomic mass of Ag+ =107.86 g/mole
molar mass of Ag₂O₃S = 295.8 g/mole
∴
The mass of the Silver (Ag) in grams is:
= 0.82 gram of Ag+
2.
Here, the total amount of Ag₂O₃S = unknown
Atomic mass of Ag+ = 107.86 g/mole
molar mass of Ag₂O₃S = 295.8 g/mole
amount of Ag+ = 1.75 g
∴
The mass of Ag₂O₃S = 
= 4.79 g of Ag₂O₃S
The number of electrons shared between the atoms in a I₂ molecule is two (2).
Explanation:
An iodine atom has 53 electrons and its electron configuration is;
2. 8. 8. 18. 17
1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁵
Note that the outermost p shell has 5 electrons while it can accommodate a maximum of 6 for stable electron configuration. Therefore an Iodine atom needs one (1) electron to acquire nobility. Two Iodine atoms will, therefore, share two electrons (each from one of their p sub-shell ) by covalent bonds to form I₂

That is a tetrahedral arrangement, with an angle of 109.5°. Nothing changes in terms of the shape when the hydrogen atoms combine with the carbon, and so the methane molecule is also tetrahedral with 109.5° bond angles.
