Volume of the peat moss = 
= 
Convert the above volume into 
Thus, volume in is:
Volume of peat moss = 
= 
Now,
Total volume by using area and depth of the peat moss = 
= 
= 
Convert above values in 
to get the value of volume in :
Thus, volume in is:
Total volume = 
= 
= 
Now, number of bags is calculated by the ratio of total volume of the peat moss to the volume of the peat moss.
Substitute the values of volume in above formula:
= 
≅ 
bags
Thus, number of bags of peat moss are needed to cover an area measure 
by 
to a depth of 
are bags.
Answer:
dispersion, dipole-dipole, and hydrogen bonding
Explanation:
The pictured compound is an amine. Amines have high boiling points. Amines have such high boiling points because they posses about three different kinds of intermolecular interactions, viz; hydrogen bonds, dispersion forces and dipole-dipole interactions.
The dipole interactions and hydrogen bonds arise from the fact that the N-H bond is polar. Also recall that a hydrogen bond is formed when hydrogen is bonded to an electronegative element. Hydrogen bonds lead to significant intermolecular association and high boiling points.
Hence the three kinds of intermolecular forces present in the pictured compound are; hydrogen bonding, dipole interactions and dispersion forces.
Answer:
A. Nutrients are released into the soil
Explanation:
The resonance compounds are compounds that have the same position of the atoms (same quantity and elements) but the position of the electrons arround them is different in each resonance compound.
In reality, the compound switches between all the resonance structures it has.
One example of resonance Lewis structures is the Ozone's as can be seen in the figure.
Answer:
The answer to the question is
50 % of the original amount of potassium 40 will be left after one half life or 1.25 billion years
Explanation:
To solve the question we note that the half life is the time for half of the quantity of substance that undergoes radioactive decay to disintegrate, thus
we have
half life of potassium 40 K₄₀ = 1.25 billion years
To support the believe tht the rock was formed 1.25 billion years ago we have
After 1.25 billion years we have
= 
=0.5 of 
will be left or 50 % of the original amount of potassium 40 will be left
