What is the empirical formula for C8H20F4
1 answer:
The given formula of can be written as
<u>Explanation:</u>
Empirical formula is one of the way of representing the structural arrangement of any molecule. With this formula, we can guess the nearest atom or element in a heterogeneous molecules. Mostly the empirical and molecular formula differs for organic compounds.
As in organic compounds consists of chain of carbon and hydrogen elements. So while arranging them in a relation, we should remember that carbon should contain 4 nearby atoms and hydrogen can share only one electron to its nearby atom. Thus, a carbon can have three hydrogen and one carbon as neighbouring element.
So the given formula of can be written as

Answer:
Explanation:
Zn + 2HCl = ZnCl₂ + H₂
A ) mole of Zn = 2.65 / 65
= .04 mol
mole of HCl required = .04 x 2 mol
.08 mol
If v be the volume required
v x 6 = .08
v = .0133 liter
= 13.3 cc
B )
volume of gas at NTP :
moles of gas obtained = .04 moles
= 22.4 x .04 liter
= .896 liter
we have to find this volume at given temperature and pressure
= 1.175 liter.
C )
.04 mole of zinc chloride will be produced
mol weight of zinc chloride
= 65 + 35.5 x 2
= 136 gm
.04 mole = 136 x .04
= 5.44 gm
Answer: The electronic configuration of Chlorine will be
Explanation: Chlorine is an element which belongs to the P-block of the periodic table. Its atomic number is 17.
Atomic Number = Number of electrons
Number of electrons = 17
The nearest noble gas which lies to Chlorine is Neon which has 10 electrons. Rest of the 7 electrons are filled in the 3s and 3p orbitals. Hence, the electronic configuration of Chlorine is
