What is the oxidation for nitrogen in nitric oxide?
1 because oxygen is -2 so then N must be 2 divided by two =1 N2O 2(N) + (-2) = 0 2 times N (the unknown) + the oxidation number of oxygen = 0 because its a neutral compound so 2N = 2 N=2/2 = +1
A student has one mole of an unknown compound in a test tube The mass of the compound is 58.5 g The compound could be?
The compound could be sodium chloride (NaCl) since its molar mass is 58.5 g/mol.
What information do you need to know to determine the chemical formula of an unknown compound?
We need to know the elements contained in this molecule and the percentages.
A 76.00 g sample of unknown compound contains 12.90g of sulfur. what is the percentage by mass of sulfur in the compound?
The percentage by mass of sulfur in the compound is 16.97%. This was calculated by dividing the mass of sulfur (12.90g) by the total mass of the compound (76.00g) and then multiplying by 100 to get the percentage.
What color is Francium?
Pure francium is a silvery-white color, but it is highly reactive and quickly tarnishes to a darker color when exposed to air due to oxidation.
How is an unknown oxidation state of an element within a compound?
It is determined from known oxidation states of other elements.
How is the unknown oxidation state of an element within a compound determined?
The unknown oxidation state of an element in a compound can be determined by using a set of rules based on the known oxidation states of other elements in the compound. First, assign oxidation states to all known elements according to standard rules, such as those for group elements and common ions. Then, apply the principle that the sum of oxidation states in a neutral compound must equal zero or match the charge of a polyatomic ion. By solving the resulting equation, the unknown oxidation state can be deduced.
How is an unknown oxidation state of an element within a compoud determined?
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
What is the oxidation number of the each element in the following compound-K2TaF7?
In K2TaF7, the oxidation number of K is +1, Ta is +5, and F is -1. This is determined by assigning known oxidation numbers to the compounds (K is typically +1 and F is -1) and solving for the unknown ones (Ta).
How to calculate the oxidation number?
To calculate the oxidation number of an element in a compound, follow these steps: 1. Assign known oxidation numbers, such as +1 for hydrogen and -2 for oxygen. 2. Use algebraic rules to solve for the unknown oxidation number based on the compound's overall charge or known oxidation numbers of other elements. 3. Remember that the sum of oxidation numbers in a compound equals zero, or equals the compound's net charge if it is an ion.
The oxidation number of Fe in Fe2S3 is?
The oxidation number of Fe in Fe2S3 is +3. This can be determined by setting up an equation where the total oxidation number of the compound is equal to zero, and solving for the unknown oxidation number of Fe.
What is the oxidation number of Mn in K2Mno4?
The oxidation number of Mn in KMnO4 is +7. This can be determined by assigning the known oxidation numbers of potassium (+1) and oxygen (-2) and solving for the unknown oxidation number of manganese.
What is the oxidation number for P in H3P2O7?
The oxidation number of Phosphorus (P) in H3P2O7 is +5. This can be determined by assigning hydrogen an oxidation number of +1 and oxygen an oxidation number of -2, then setting up an equation to solve for the unknown oxidation number of Phosphorus.
What is the oxidation state of P in PO33?
The oxidation state of P in PO33- is +3. This can be determined by assigning -2 to each oxygen atom and solving for the unknown oxidation state of phosphorus to ensure the overall charge of the ion is balanced.
What is the oxidation number of phosphorus in H4P2O7?
The oxidation number of phosphorus in H4P2O7 is +5. This can be calculated by taking into account the known oxidation states of hydrogen (+1) and oxygen (-2), and solving for the unknown oxidation state of phosphorus to ensure the overall charge of the compound is neutral.
What the composition of a melting point mixture?
A melting point mixture typically consists of a 1:1 ratio of the compound being tested and a known standard compound, such as benzoic acid. The mixture is heated slowly to determine the melting point range of the unknown compound. By comparing the melting point range of the unknown compound to that of the standard, the identity or purity of the unknown compound can be determined.
What is oxidation state of Mn?
4SnO32-calculation can be done to find the unknown oxidation state of tinlet; X=Snbecause of the overall charge is -2, the equation must equal to -2X + 3(oxidation no of oxygen)=-2X + 3(-2)=-2X + (-6) = -2X = +4So, the oxidation no for tin in SnO32- is +4this calculation can be rechecked to confirm the answer by substituting +4 back in the equation;(+4) + (-6) = -2and here we gothe answer was correct
