Answer:NH4F ( ammonium fluoride)
Explanation:
NH4 is a cation with a positive 1 charge and F an anion having negative 1 oxidation number. Do the criss-cross rule for both cations and anions. So the charge of NH4 which is +1 will be the subscript of F and the charge of F which is -1 will be the subscript of NH4. Both have the same numerical value of 1 so we can cancel them out in the final equation of the chemical compound.
Ionic bonds are a metal and a non metal bond and a covalent bond is two no metals banded together.
4 In the open chain, 5 in the cyclic. Just like glucose.
2 moles of H₂ : 1 mole of O₂ : 2 moles of H₂O
number of moles of H₂ : number of moles of H₂O = 1 : 1
There are 5 moles of hydrogen so there must be 5 moles of water too.
The mass of H₂O is 90 g.
