It is true because you can die of anything thus haveing an excess of ANYTHING can kill you and cause a family unhappiness
Covalent compounds are held together with an intra molecular attraction which is weaker than metallic bond
hence covalent compounds exist as liquids, gases and soft solids
Answer:
The compound with the correct formula is;
A. MNO₃
Explanation:
The number of oxidation states in the metal, M = One oxidation state
The formula of the compound formed by the metal, M = MHCO₃
We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1
Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;
The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.
Answer is: the structural formula of fluorine is F-F.
The structural formula is a graphic representation of the molecular structure, it shows arrangement of the atoms and the covalent bonds between them.
Fluorine is molecule with molecular formula F₂.
Between two flourine atoms there is nonpolar, single, covalent bond.
D. Physical change
Cause you are the one doing the change to it and physical change means You.
