The molecule with same molecular formula but different arrangement of atoms is said to be an isomer.
When 2,2-dimethylbutane reacts with chlorine in the presence of light gives three isomers that is
(3-chloro-2,2-dimethylbutane),
(1-chloro-2,2-dimethylbutane) and
(1-chloro-3,3-dimethylbutane).
In above case, the molecular formula of all isomers are same i.e.
but chlorine is arranged in different positions of carbon. Thus, results isomers.
The reaction is shown in the image.
Answer:
B. Increase the mass of one of the objects.
E. Decrease the distance between the objects.
Explanation:
To effect an increase in the gravitational force between two objects, the mass of both objects should be increased and the distance between them reduced.
This is derived from the Newton's law of universal gravitation:
- It states that "the force of gravity between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".
Therefore, if the mass of the two bodies are increased and the distance between them reduced, the gravitational force of attraction will increase.
The crust of the Earth is thickest beneath the continents.
Answer:
The given isotope is Br 80
If 35 protons present then its atomic number is 35
Mass number is 80 so its meutrons are 45 because proton+ neutron = mass number
Its electron are 36 because of negative one charge
Explanation:
Answer:
V₂ = 22.23 mL
Explanation:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
Given data:
Initial volume = 25 mL
Initial pressure = 725 mmHg (725/760 =0.954 atm)
Initial temperature = 20 °C (20 +273 = 293 K)
Final pressure = standard = 1 atm
Final temperature = standard = 273.15 K
Final volume = ?
Solution:
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 0.954 atm × 25 mL × 273.15 K / 293 K × 1 atm
V₂ = 6514.63 mL . atm . K / 293 K . atm
V₂ = 22.23 mL
