+2 for Mg
+4 for C
-2 for each O
Ah, isn't that a lovely question? To find the number of moles in 100 g of MgCO3, we first need to know the molar mass of magnesium carbonate (MgCO3). Then, we can use the formula: moles = mass / molar mass. Just like painting a happy little tree, it's all about following the steps and enjoying the journey to the answer.
+1 for H -1 for I
The oxidation number of Li in LiNO2 is +1, as it typically has an oxidation number of +1 in its compounds.
Phosphorus increases its oxidation number in this reaction. In H3PO4, phosphorus has an oxidation number of +5, and in K3PO4, it has an oxidation number of +5 as well. This means that phosphorus's oxidation state remains the same throughout the reaction.
The oxidation number of silicon (Si) in SiO2 is +4. Oxygen (O) typically has an oxidation number of -2, so in this compound, the total oxidation number must equal zero. Since there are two oxygen atoms in SiO2, the oxidation number of silicon must be +4 to balance out the -4 from the oxygens.
Magnesium and carbonate are divalent.

The ratio of MgCO3 to WHAT!
Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
Silicon's oxidation number is +4.Oxygen's oxidation number is -2
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
Oxidation number of Nb is +4. Oxidation number of O is -2.
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
The oxidation number for H is +1, and the oxidation number for O is -1.
