Answer:
The electronegativity differences between carbon and oxygen are not very large.
Explanation:
Between the atoms of carbon monoxide exists a covalent bond which attaches the carbon to the oxygen.
In this type of bonding, both atoms shares a given number of valence electrons to attain chemical stability.
A substance is polar when there is a distinct charge separation between the species.
For covalent bonds, the electronegativity difference plays in important role in determining the polarity of the compound. When the difference is large, the compound will be polar but when the difference is very small or zero, no polarity will exist.
In between carbon and oxygen of carbon monoxide, the electronegativity difference is very low.
Answer:
36 valence electrons
Explanation:
Given CBr₂COHNH₂ => Br₂C = C - O - H
|
H - N - H
#Valence e⁻s = 2Br + 2C + 3H + 1N + 1O = 2(7) + 2(4) + 3(1) + 1(5) + 1(6)
= 14 + 8 + 3 + 5 + 6 = 36 valence electrons
Addendum ...
#Bonded e⁻s = 2Br + 2C + 3H + 1N + 1O = 2(8) + 2(8) + 3(2) + 1(8) + 1(8)
= 16 + 16 + 6 + 8 + 8 = 54 bonded electrons
#Covalent Bonds = #Valence e⁻ - #Bonded e⁻ / 2 = (54 - 36) / 2 = 9 cov. bonds.
Answer:
Explanation:
The frequency and the wavelength of a wave are related by the equation
where
v is the speed
f is the frequency
is the wavelength
For the sound wave in this problem, we have
f = 634 Hz (frequency)
(wavelength)
Therefore, the speed of the wave is
The speed of sound in air depends on the temperature according to the equation
where T is the temperature.
In this problem, we know the speed, so we can calculate the temperature:
Molar mass neon = <span>20.1797 g/mol
20.1797 g ---------- 6.02x10</span>²³ atoms
? g ------------ 3.0 x 10²³ atoms
mass = 3.0 x 10²³ * <span>20.1797 / 6.02 x 10</span>²³
mass = 6.054x10²⁴ / 6.02 x 10²³
mass = 10.05 g
hope this helps!
