When you have two nonmetals bounded together, you form a covalent bond. When the covalently-bonded molecule consists of two atoms of different elements, you give the second atom the prefix "mono-", so you should have "sulfur monoxide" instead.
The chemical formula "Mg2O2" is incorrect. The correct formula for magnesium oxide is "MgO". Magnesium oxide is formed by the combination of one magnesium atom with one oxygen atom, not two.
H2SO4 [water plus Sulphur Dioxide]. Correct me if I'm wrong but isn't it Sulphur Trioxide?
The names "Calcium and sulfur" and "Sulfur calcium" are incorrect because they do not follow the standard naming conventions for chemical compounds. In this case, the correct name for the compound formed by calcium and sulfur would be calcium sulfide.
The mineral lime is essentially calcium that contains inorganic material the is predominantly either oxides, carbonates or hydroxides. The basic chemical formula of lime is CaO and it is known as either calcium hydroxide or calcium oxide.
The chemical formula CaCl2 represents calcium chloride. It is correct as it shows that the compound contains one calcium atom and two chlorine atoms.
The chemical formula "Mg2O2" is incorrect. The correct formula for magnesium oxide is "MgO". Magnesium oxide is formed by the combination of one magnesium atom with one oxygen atom, not two.
It is SnO2Why? Because:Tin has a charge of 4 and Oxygen has a charge of 2. Their charges are switched to make a compound; therefore, the chemical formula would be written as Sn2O4. Then, you have to simplify that so it would be written as SnO2.
So it is wrong equation .Symbols are very important
the ions are 67 and one half since the molecular structuere
H2SO4 [water plus Sulphur Dioxide]. Correct me if I'm wrong but isn't it Sulphur Trioxide?
The chemical formula i2Ca is incorrect because the element symbol "i" is not recognized in the periodic table. The correct chemical formula for calcium iodide is CaI2, where calcium has a +2 charge and iodine has a -1 charge.
The names "Calcium and sulfur" and "Sulfur calcium" are incorrect because they do not follow the standard naming conventions for chemical compounds. In this case, the correct name for the compound formed by calcium and sulfur would be calcium sulfide.
I'm pretty sure you have your formula wrong. Oxygen has a net charge of -2. So therefore, the equation must be written as 2Hg with a net charge of 2+ plus CO3 with a net charge of 2-. So, you do your math here, and the answer should be Hg3CO3
The mineral lime is essentially calcium that contains inorganic material the is predominantly either oxides, carbonates or hydroxides. The basic chemical formula of lime is CaO and it is known as either calcium hydroxide or calcium oxide.
The chemical formula CaCl2 represents calcium chloride. It is correct as it shows that the compound contains one calcium atom and two chlorine atoms.
C2S is the chemical formula for carbon disulfide, while CS2 is the chemical formula for carbon disulfide. The placement of the elements in the formula indicates the chemical structure and arrangement of atoms in the molecule. In the case of carbon disulfide, the carbon atom is bonded to two sulfur atoms, hence C2S.
CuH2PO4 - this is wrong! The correct answer is: Cu(H2PO4)2
