Answer: 996 mmHg
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number
of particles.
According to the ideal gas equation:

P = Pressure of the gas = ?
V= Volume of the gas = 25.5 L
T= Temperature of the gas = 13°C = (273+13) K = 286K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 1.42
(760mmHg=1atm)
Thus pressure of this gas sample is 996 mm Hg.
<u>Answer:</u> The lewis dot structure is attached below.
<u>Explanation:</u>
A Lewis dot structure is defined as the representation of atoms having electrons around the atom where electrons are represented as dots.
A ketene is an organic compound having general formula R′R″C=C=O, where R and R' are two different/same monovalent chemical groups.
The given chemical compound having formula
is represented as
.
Total number of unshared electrons = 4 (left on oxygen atom only)
The lewis dot structure of
is given in the image below.
Answer:
Fluorine
Explanation:
It is a non-metal does not conduct electricity
Answer:
sp3 hybridization
Explanation:
Hybridization means the mixing of atomic orbitals to yield hybrid orbitals with characteristics that are different from that of the isolated atomic orbitals before the combination.
sp3 hybridization occurs when one s orbital is mixed with three p orbitals to yield four sp3 hybrid orbitals which can be used to bond to a central atom.
The central atom is then located at the center of a regular tetrahedron at a bond angle of 109°.
