they are called The 7 Seas
Start with 0.5 g of each - place each in a separate 20 ml beaker containing 10 cc water. Swirl each beaker to dissolve the solids - The KCl will dissolve completely - the lead salt will not.
Answer:
Five electrons are gained.
Explanation:
Oxidation number or oxidation state of an atom in a chemical compound is the number of electrons lost or gained. It is also defined as the degree of oxidation of the atom in the compound.
This is a theoretical number which can help to decipher the oxidation and reduction in a redox reaction.
Oxidation is the loss of electrons. The specie which is oxidized has has elevation in its oxidation state as compared in the reactant and the products.
The given reaction is shown below as:
Manganese in has oxidation state of +7
Manganese in has an oxidation state of +2
<u>It reduces from +7 to +2 . It means that 5 electrons are gained.</u>
Answer:
<em><u>Rows in the periodic table are called periods</u></em>. As one moves from left to right in a given period, the chemical properties of the elements slowly change. <em><u>Columns in the periodic table are called groups</u></em>. Elements in a given group in the periodic table share many similar chemical and physical properties
