OH - REFERS TO THAT OT IS ION OF BASE IF THE SOLUTION OF BASE HAS PH 6.10 SO IT IS ACIDIC SO IT IS NOT POSSIBLE THAT SOLUTION OF OH- IS PH 6.10
Answer : The correct Lewis-dot structure of nitrate ion is shown below and the nitrogen has 4 covalent bonds.
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule. The number of valance electrons are shown by 'dot'.
The given molecule is, nitrate ion
As we know that nitrogen has '5' valence electrons and oxygen has '6' valence electron.
Therefore, the total number of valence electrons in 
= 5 + 3(6) + 1 = 24 electrons
According to Lewis-dot structure, there are 8 number of bonding electrons and 16 number of non-bonding electrons.
The correct Lewis-dot structure of nitrate ion is shown below.
Answer:
The symbol for this ion is Ni^2+
Not sure though
N2 +H2 →2 NH3
"Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3."
Answer:
Option a
Explanation:
Ester ethyl butanoate is a Chemical compound with Molar mass of 116.16 g/mol, the Boiling point is 121 °C and the Density is 879 kg/m³.
Looking at the chemical representation of the compound, it can be shown that the chemical compound contains the an ester functional group and this it is formed through the reaction of a -COOH containing compound/salt and an alcohol.
The chemical representations showing the chemical reaction is given below;
CH3CH2CH2COOCH2CH3 + Acid(H2O, H^+) =========> C2H5OH + C4H8O2.
Thus, acidic hydrolysis of the ester gives ethyl alcohol and butanoic acid.
