+1 for Na, +1 for H, +6 for S and -2 for each O
The oxidation number of H in NaH is -1. Sodium (Na) typically has an oxidation number of +1, so in order for the overall compound to be electrically neutral, hydrogen (H) must have an oxidation number of -1.
The oxidation number for H in H3PO2 is +1, as it is in compounds with nonmetals. The oxidation number for P in H3PO2 is +1, as the sum of oxidation numbers in a compound is zero.
The oxidation number of H in H3PO4 is +1. In a compound, the oxidation numbers of all the elements add up to the overall charge of the compound, which is 0 in this case. Since the oxidation number of oxygen is typically -2 and there are four oxygen atoms in H3PO4, the oxidation number of hydrogen must be +1 to balance the charge.
The oxidation number for hydrogen in the compound HCl is +1. Hydrogen typically has an oxidation number of +1 when bonded to nonmetals like chlorine in covalent compounds.
In NH4₂SO3, the oxidation number of N is -3 (since H is +1), the oxidation number of S is +3, and the oxidation number of O is -2. The sum of the oxidation numbers in a neutral compound is always zero, so the oxidation number of H is +1.
The oxidation number of H in NaH is -1. Sodium (Na) typically has an oxidation number of +1, so in order for the overall compound to be electrically neutral, hydrogen (H) must have an oxidation number of -1.
+1 for H -1 for I
The oxidation number for H in H3PO2 is +1, as it is in compounds with nonmetals. The oxidation number for P in H3PO2 is +1, as the sum of oxidation numbers in a compound is zero.
The oxidation number of H in H3PO4 is +1. In a compound, the oxidation numbers of all the elements add up to the overall charge of the compound, which is 0 in this case. Since the oxidation number of oxygen is typically -2 and there are four oxygen atoms in H3PO4, the oxidation number of hydrogen must be +1 to balance the charge.
The oxidation number for hydrogen in the compound HCl is +1. Hydrogen typically has an oxidation number of +1 when bonded to nonmetals like chlorine in covalent compounds.
In NH4₂SO3, the oxidation number of N is -3 (since H is +1), the oxidation number of S is +3, and the oxidation number of O is -2. The sum of the oxidation numbers in a neutral compound is always zero, so the oxidation number of H is +1.
Hydrogen chloride (HCl) is a covalent compound, where hydrogen typically has an oxidation number of +1 and chlorine has an oxidation number of -1.
O.S. of H = +1 O.S. of O = -2 O.N. of cpd = 0
The oxidation number of Al in NaAlH4 is +3. This is because Na has an oxidation number of +1, H has an oxidation number of -1, and the overall compound has a neutral charge. Therefore, the oxidation number of Al can be calculated as +3.
The oxidation number of H in H2SO4 is +1, the oxidation number of S is +6, and the oxidation number of O is -2. This is because the sum of the oxidation numbers in a neutral compound like H2SO4 must equal zero.
The oxidation number of xenon (Xe) in H4XeO6 is +4. This is because hydrogen (H) is typically assigned an oxidation number of +1, and oxygen (O) is typically assigned an oxidation number of -2. By adding up the oxidation numbers for each element in the compound, it must equal the charge of the compound, which is 0 in this case.
The oxidation number for H is almost always 1+.
