Answer: Every action force results in an equal and opposite reaction force.
Explanation: newtons law
Answer:
Explanation:
mass of 1mole of brick = mass of 1 brick x avagadro number
= 4 kg x 6.022 x 10^23 bricks = 2.4 x 10^24 kg
No. of moles of bricks have a mass equal to the mass of the earth
= mass of earth / mass of 1 mole of brick
= [ 6 x 10^27 ] / [ 2.4 x 10^24 ]
= 2.5 x 10^3
= 2500 moles
<em> $ 434.40</em>
<em>41 miles ............ 1 gallon</em>
<em>4700 miles .......x gallon</em>
<em>x = 4700×1/41 = 114.63 gallons</em>
<em />
<em>114.63 gallons×$3.79 ≈ $ 434.40</em>
The condensed structure of given compounds are shown in the below image.
<h3>What is functional group?</h3>
Functional group is the specific group which is present in an organic compound gives information about the properties of that compound.
- In 1,2-propanediol compound hydroxyl functional group is present on the 1st and 2nd position.
- In Ethyl methyl ether, ether functional group is present.
- In Dichloromethane, two atoms of chlorine groups are present.
Hence, structure of the given compounds are shown in the below image.
