In order: B, D, A, A, A. C, A
So,
Let's draw the structures for the following hydrocarbons:
Cyclohexane
We can draw it using the fact that it is a cycloalkane with six carbons:
Cyclohexene
It also contains six carbons with a hexagonal form, but the difference is that there's double bond on it:
Benzene
It has six carbons but there's an alternating double bond as follows:
Toluene
It has the same structure as benzene but it is bonded to a methyl group outside the benzene:
<u>Answer:</u> The concentration of the diluted solution is 0.4788M
<u>Explanation:</u>
To calculate the concentration of the diluted solution, we use the following equation:

where,
are the molarity and volume of HCl solution
are the molarity and volume of the diluted HCl solution.
We are given:

Putting values in above equation, we get:

Hence, the concentration of the diluted solution is 0.4788M
<h2>
Answer:</h2>
Both of them will have same kinetic energy.
<h2>
Explanation:</h2>
- Kinetic energy is the energy of motion, every object in motion posses some kinetic energy.
- Kinetic energy can be calculated by the given formula,
i.e, K.E = 1/2 mv² .
Where, K.E is kinetic energy,
m is mass of the object
v is the velocity of the object
- On observing the formula we can state that K.E is directly proportional to mass(m) and velocity(v) of the object.
- Obviously, birds have more mass than bees but in question it has given 10 Kg of bees and 10 Kg of birds which means mass is same and also both of them are travelling with same velocity i.e 10m/s and hence both of them will have same kinetic energy(as both of the variables i.e m and v are same).
Result: Both bees and birds have same kinetic energy.
elements are classified to study their properties and similarities and differences between each other more aqurately
hope it helps...!!!!
