Carbon-12 and carbon-13 are isotopes of carbon.
ohaa [14]

Answer:

Isotopes of an element share the same number of protons but have different numbers of neutrons. Let's use carbon as an example. There are three isotopes of carbon found in nature – carbon-12, carbon-13, and carbon-14. All three have six protons, but their neutron numbers - 6, 7, and 8, respectively - all differ.

The zero order reaction 2N2O→2N2+O2 has the reaction constant k is 6.28×10−3 molL s. If the initial concentration of N2O is 0.96
Talja [164]

<u>Answer:</u> The concentration of N_2O in three significant figures will be 0.899 mol/L.

<u>Explanation:</u>

For the given reaction:

2N_2O\rightarrow 2N_2+O_2

The above reaction follows zero order kinetics. The rate law equation for zero order follows:

k=\frac{1}{t}([A_o]-[A])

where,

k = rate constant for the reaction = 6.28\times 10^{-3}\text{ mol }L^{-1}s^{-1}

t = time taken = 10 sec

[A_o] = initial concentration of the reactant = 0.962 mol/L

[A] = concentration of reactant after some time = ?

Putting values in above equation, we get:

6.28\times 10^{-3}=\frac{1}{10}(0.962-[A])

[A]=0.899mol/L

Hence, the concentration of N_2O in three significant figures will be 0.899 mol/L.
