Answer:
One triple bond and four non bonding electrons
Explanation:
In considering the lewis structure of carbon monoxide, we must remember that the molecule contains a total of ten valence electrons. Four are the valence electrons that are present on the valence shell of carbon while six are the valence electrons on oxygen. Some of these valence electrons participate in bonding in the CO molecule.
Out of the six valence electrons on oxygen, two valence electrons participate in bonding with carbon while the other four electrons remain localized on the oxygen atom as two lone pairs of electrons.
Hence there are four nonbonding electrons in the lewis structure of CO as well as one triple bond.
First, we determine the energy required to melt one gram of ice. This is given by:
Energy = mass * latent heat of fusion
Energy = 1 g * 334 J/g
Energy = 334 J
Next, we use Planck's equation which is:
Energy = number of photons * Planck's constant * speed of light / wavelength
334 = n * 6.64 x 10⁻³⁴ * 3 x 10⁸ / 5.49 x 10⁻⁶
n = 9.20 x 10²¹
9.20 x 10²¹ photons need to be absorbed by the ice.
Answer:
Explanation:
Attach is the net ionic equation
Answer:
a) Carbon.
Explanation:
The organic chemistry is normally based on the chemical elements Carbon, Hydrogen,oxygen, sulphur and Nitrogen. Sometimes a mixture or compound of one or more of these will be found such as (carbohydrates, fats, proteins). The varieties of organic molecules are based on these atoms, with carbon as the skeleton of the organic molecule.
Hence out of the four options given we find that though nitrogen, sulphur are also common in organic the most common is the first option
a) Carbon.
There are certain factors which affects Diffusion, and they are :
1) Particle Size
2) Temperature
3) Concentration difference
4) Distance between the particles
Hope this helps!
