Answer:

No

Explanation:

A compound is when two different elements join. The model only shows two similar elements, which form a molecule, not a compound.

A compound is a substance composed of 2 or more chemical elements.
The model does not represent a compound because it shows two atoms of the same element combined. To be a compound the model would need to contain atoms of different element, represented by different colored balls. Therefore, the picture does not represent a compound. :)

A compound contains 25.93% N and the rest is oxygen. What is the empirical formula for the compound?
Mnenie [13.5K]

Answer: NO2

Explanation:

                                  N                                O

Divide each by its    25.93                       74.07

mass number              14                             16

                                     2                              4

Divide both by the       2                               2

smaller (i.e. 2)               1                                2

Therefore, the empirical formula = NO2

20 ML of a gas at 200 K is heated until the new volume is 55ML what is the final temperature of the gas
MrRa [10]

Answer:

T2 = 550K

Explanation:

From Charles law;

V1/T1 = V2/T2

Where;

V1 is initial volume

V2 is final volume

T1 is initial temperature

T2 is final temperature

We are given;

V1 = 20 mL

V2 = 55 mL

T1 = 200 K

Thus from V1/T1 = V2/T2, making T2 the subject;

T2 = (V2 × T1)/V1

T2 = (55 × 200)/20

T2 = 550K

Consider the reaction.
Alex_Xolod [135]

Note the signs of equilibrium:-

  • Reaction don't procede forward or backward
  • Concentration of products and reactants remains same .

So

if

Concentration of A is 2M then concentration of B should be same .

So equilibrium constant K is 1

\\ \rm\rightarrowtail K=\dfrac{[Products]^a}{[Reactants]^b}

So

  • [B]=[A]^2
  • [B]=2^2
  • [B]=4M
