Answer: The correct option is C.

Explanation: For a given chemical formula $C_3H_6O_2$

3 different elements are present in this molecule that are Carbon, Hydrogen and Oxygen.

Number of Carbon atoms present = 3

Number of Hydrogen atoms = 6

Number of oxygen atoms = 2

Total number of atoms in the given molecule = 3 + 6 + 2 = 11

Hence, This molecule is made up of total 11 atoms of 3 different elements. Therefore, the correct option is C.

grandymaker [24]

Answer:

(a) backward direction

(b) forward direction

(c) no change

Explanation:

(a)

On increasing the concentration of NO , the reaction will go in backward direction , as, according to le chatelier's principle ,

In a chemical equilibrium , when the concentration , pressure or temperature is changed , the equilibrium of the reaction is disturbed , hence, in order to gain attain the equilibrium the reaction moves in order to counteract the changes.

So, in this case, the reaction goes back , to reduce the increased concentration of NO.

(b)

On increasing the concentration of NO2 , the reaction goes in forward direction ,

according to le chatelier's principle ,

the reaction moves in forward direction , to reduce the increased concentration of NO2.

(c)

No change ,

As, changing the volume , does not effect change in the concentration,

Hence,

No change , as the system is allowed to expand to 5 times its initial value.

If the volume of a rock is 8 cm^3 and its’ mass is 16 g, what is its’ density?

attashe74 [19]

We know, Density = Mass / Volume

Substitute the given values,
d = 16/8
d = 2 g/cm³

In short, Your Answer would be: Option C

Hope this helps!
