Energy is released as a bond is formed
Answer:
Decrease by the distance squared
Explanation:
<u><em>Gravitation formula:</em></u>
where
'F' is the force of attraction between the two bodies (Gravitational force),
'G' is the universal gravitational constant,
'M' is the mass of the first object,
'm' is the mass of the second object and
'r' is the distance between the centers of each object.
Hence, with the increase by distance between two objects , the gravitation decreases by the distance squared
Answer:
Comprehensive
Explanation:
In the given problem, it was stated that each team member has a great deal of discretion in terms of their overall performance, throughput, and with whom they can interact with in the course of their civic duties while collaborating to accomplish the team work. Therefore, this type of independence is comprehensive independence which is in contrast to other types of independence such as reciprocal, virtual, and sequential. The correct answer to the given problem is <u>comprehensive</u> independence.
Answer:
C) They all have single covalent bonds.
Explanation:
The given hydrocarbons Butane,Ethane,Methane,Propane belongs to alkane group.
In alkane group consists of hydrogen and carbon in which carbon_carbon bonds are single and carbon_hydrogen bond is also single.
The elements of this group makes bond by sharing of electrons that means they form single covalent bond.
Butane have 4 , Ethane has 2, Methane has 1, and Propane has 3 carbon atoms.
Since they have different number of carbon atoms so their structural formula also differs.
Answer: The first isotope has a relative abundance of 79% and last isotope has a relative abundance of 11%
Explanation: Given that the average atomic mass(M) of magnesium
= 24.3050amu
Mass of first isotope (M1) = 23.9850amu
Mass of middle isotope (M2)=24.9858amu
Mass of last isotope(M3)= 25.9826amu
Total abundance = 1
Abundance of middle isotope = 0.10
Let abundance of first and last isotope be x and y respectively.
x+0.10+y =1
x = 0.90-y
M = M1 × % abundance of first isotope + M2 × % of middle isotope +M3 ×% of last isotope
24.03050= 23.985× x + 24.9858 ×0.10 + 25.9826×y
Substitute x= 0.90-y
Then
y = 0.11
Since y=0.11, then
x= 0.90-0.11
x=0.79
Therefore the relative abundance of the first isotope = 11% and the relative abundance of the last isotope = 79%
