The relation between the elements electro negativity, atomic radius, and ionization energy levels.
Its a polar molecule
Hope this helps you hon :)
Answer:
1 mole
Explanation:
To get the answer to this, we need to write the correct chemical equation:
HCl + NaOH ------》NaCl + H2O
As seen in the balanced chemical equation above, one mole of hydrochloric acid will react with one mole of sodium hydroxide to yield one mole of sodium chloride and one mole of water
Answer: :)
Explanation:
In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom
Answer:
THE EMPIRICAL FORMULA FOR THE PURE HYDROCARBON IS CH4
Explanation:
A pure hydrocarbon contains carbon and hydrogen
Percentage composition of carbon = 74.5 %
Percentage composition of hydrogen = 25.5
In order to calculate the empirical formula of this hydrocarbon, you follow these couple of steps.
write out the percentage composition and divide by the relative atomic mass of the respective constituents.
Carbon = 74.5 / 12 = 6.2083
Hydrogen = 25.5 / 1 = 25.5
Next is to divide the values by the lowest factor
Carbon = 6.2083 / 6.2083 = 1
Hydrogen = 25.5 / 6.2083 = 4.1
Next is to write the empirical formula:
C H4
In conclusion the empirical formula for the pure hydrcarbon is CH4
