How is an unknown oxidation state of an element within a compound?
It is determined from known oxidation states of other elements.
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 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.
Suppose you were given an unknown liquid and asked to determine if it was an element a compound or a mixture What would you do How would this help you find out what it was?
I would conduct various physical and chemical tests on the liquid. By testing its properties like boiling point, density, conductivity, and by performing chemical reactions with other substances, I can determine if the liquid is an element (made of the same type of atom), a compound (made of different types of atoms chemically bonded), or a mixture (combination of two or more substances that are not chemically bonded). This process helps to identify the nature of the unknown liquid based on its characteristics and behavior.
How do you identify whether the unknown chemical is element or compounds?
Previous answers are off point. Presumably you are given a sample of something and want to know whether it is is a compound or an element. There are several ways of finding out:- Investigate its chemistry. See how it reacts with oxygen, hydrogen, calcium, or various acids.- Investigate its physical chemistry. Does it have a well defined melting and boiling point? If not, it isn't an element.- X-ray studies. The absorption edges from an x-ray spectrum will identify the element(s) that may be present.

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 element forms a compound having the formula KXO4?
The element that forms a compound with the formula KXO4 is potassium (K).
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.
