How is an unknown oxidation state of an element within a compound?
It is determined from known oxidation states of other elements.
Who found the element arsenic?
Arsenic was discovered in 1250 by Albertus Magnus. The place of discovery is unknown. x
An unknown substance is made only of identical atoms that cannot be broken down this substance is what?
The substance is an element. Each atom consists of the same type of nucleus and protons, with a specific number of protons determining the element's identity on the periodic table.
An unknown element in group 2 has a total number of 12 electrons and two electrons in its outer level. what is it?
beryllium
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 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 compound determined?
It is determined from known oxidation states of other elements.
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).
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.
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.
Oxidation no of C in Fe CN 6 -3?
The oxidation number of carbon in Fe(CN)6^3- is -3. To find this, you can set up the equation where the total charge of the complex ion equals the sum of the oxidation numbers of each element in the ion and solve for the unknown oxidation number.
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.
What color is the element rutherfordium?
unknown
Which describes mendeleevs use of the term ekaaluminum?
A mixture of aluminum and an unknown element.
What is oxidation state of Mn?
The oxidation states of manganese (Mn) can range from -3 to +7, with common oxidation states being +2, +4, and +7. The oxidation state of manganese in a compound can be determined based on the overall charge of the compound and the known oxidation states of the other elements present.
