The answer is 5.33 x 10^-4

to find the answer follow these steps:

the reaction is first order reaction

here k = 6.29 x 10^-4 s^-1

initial concentration = 1.00 x 10^-3

After time t = 1.000 x 10^3 s concentration is = ?

<span>So, - 6.29 x 10^-4 x 1.00 x 10^3 + ln (1.00 x 10^-3) = - 7.54 </span>

<span>C = e ^ - 7.54= 5.33 x 10^-4 M</span>

Answer:Concentration of [CH_3=N\equiv C] after [tex]1.000\times 10^3 s is 2.38\times 10^{-8} mol/L.

Explanation:

Rate constant of the reaction = k = 6.29\times 10^{-4} s^{-1}

Initial concentration of [A_o]=1.00\times 10^{-3} mol/L

Concentration after time t= [A]

t = 1.000\times 10^3 s

log[A]=2.303\times \log[A_o]-kt

log[A]=2.303\times \log[1.00\times 10^{-3}]-6.29\times 10^{-4} s^{-1}\times 1.000\times 10^3 s

[A]=2.38\times 10^{-8} mol/L

Concentration of [CH_3=N\equiv C] after [tex]1.000\times 10^3 s is 2.38\times 10^{-8} mol/L.

Answer:

Removing the worms is they first key to overcoming this problem. Thus you should ensure that the worms have not spread throughout the house/facility, or caused more damage.

Secondly, you should replace the pipes taht the worms got into, or clean them at most. If it’s simply worm droppings then just clean it, but if it’s more and worse than that alike slime then it is best to remove and replace it.

the only way the worms escaping could affect something is if they decontaminated it, or alas ate or destroyed it. Other than that if they died you could simply replace them, but e things cannot be replaced

What makes hydrogen peroxide a polar molecule?
kupik [55]
  <span>C. polar bonds and asymmetrical structure 
If the molecule contains polar bonds but it has a symmetrical structure, the polar bonds will cancel each other out so the overall molecule will be non-polar. 
On the other hand, if the molecule contains polar bonds but has an asymmetrical structure, then the polar bonds won't cancel each other out, so the overall molecule ends up being polar.
