The oxidation number of oxygen is -2, and that of chlorine is -1. Use this information to match the names of the compounds to their chemical formulas. manganese(II) chloride manganese(IV) chloride manganese(II) oxide manganese(IV) oxide MnCl2 arrowRight MnO2 arrowRight

Answer : The correct formula of manganese(II) chloride and manganese(II) oxide is and respectively.

Explanation :

As we know that the chemical formula is formed by the criss-cross method.

In criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions.

For formation of manganese(II) chloride, manganese will form having an oxidation state of +2 called as cation and anion is chloride with oxidation state of -1.Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral  .

For formation of manganese(II) oxide, manganese will form having an oxidation state of +2 called as cation and anion is oxide with oxidation state of -2.Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral  .

Hence, the correct formula of manganese(II) chloride and manganese(II) oxide is and respectively.

The oxidation number of oxygen is -2, and that of chlorine is -1

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
