Correctly balance this equation H202->H2O+O2

Chemistry
1 answer:
Savatey [412]3 years ago
8 0

Answer:

2H202(l) --> 2H2O(l) + O2(g)

Explanation:

The balanced equation above represent the decomposition of hydrogen peroxide (H2O2) to yield liquid water (H2O) and liberate oxygen gas (O2) without any heating.

In the laboratory, the rate of decomposition is increased in the presence of manganese (IV) oxide as catalyst.

Complete Question

The complete question is shown on the first uploaded image  

Answer:

a

  2NO_2 _{(g)} +  F_2_{(g)} ---->  2NO_2 F_{(g)}

b

  r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}

Explanation:

      From the question we are told that

          The formation mechanism is  

                      NO_2_{(g)} + F_2 _{(g)} ----> NO_2 F_{(g)} + F_{(g)}

                      F_{(g)} +  NO_2 _{(g)} ---> NO_2 F_{(g)}

The overall balanced equation is

              2NO_2 _{(g)} +  F_2_{(g)} ---->  2NO_2 F_{(g)}

We combined the first reactant and the last product and the balanced the number of mole

     The observable rate law is

                 r = \frac{ k [NO_2]^2 [F_2]}{[NO_2F]}

This rate law is derived from the balanced chemical equation

8.00*10^-5 mol was diluted to 500ml what is the concentration in Mol/L?
OLEGan [10]
Make sure all units are consistent. Convert ml to L first. (500ml = 0.5L). Then divide the mole by the volume which would result to 1.6*10^-4mol/L. This can also be expressed as interms of molarity (M). 1 M = 1 mol/L hence the final answer is <span>1.6*10^-4 M. </span>

Describes the difference between the formulas for nitrogen monoxide and nitrogen dioxide?
qwelly [4]

Answer:

nitrogen monoxide: NO

nitrogen dioxide: NO₂

Explanation:

Nitrogen monoxide is composed by 1 atom of O (prefix "mono-") and 1 atom of N. Nitrogen dioxide is composed by 2 atoms of O (prefix "di-") and 1 atom of N. As the oxigen atom in oxides has the valency -2 (it shares 2 electrons), the nitrogen has valency +2 in NO and +4 in NO₂.
