I think the answer is B, it keeps food from rotting as quickly and being wasted. Food-storage facilities. Food storage allows food to be eaten after some time after the harvest rather than solely immediately. This ensures that there is food even during the time when there is no harvests and also prevents wastage of food at the time of harvest
Answer : The initial rate of the reaction is, 
Explanation :
First we have to calculate the rate constant of the reaction.
Expression for rate law for first order kinetics is given by :
![k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B%5BA_o%5D%7D%7B%5BA%5D%7D)
where,
k = rate constant = ?
t = time taken for the process = 44 s
![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= initial amount or concentration of the reactant = 0.1108 M
![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= amount or concentration left time 44 s = 0.0554 M
Now put all the given values in above equation, we get:
Now we have to calculate the initial rate of the reaction.
Initial rate = K [A]
At t = 0, ![[A]=[A_o]](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA_o%5D)
Initial rate = 0.0157 × 0.1108 =
Therefore, the initial rate of the reaction is,
Use the formula PV=NRT to find the amount of moles of nitrogen gas. Then use the same formula using the amount of moles found to find the temperature
Answer:
energy is stored in the chemical bonds in molecules
Explanation:
This problem is providing two reduction-oxidation (redox) reactions in which the oxidized and reduced species can be identified by firstly setting the oxidation number of each element:
Reaction 1: 2K⁺I⁻ + H₂⁺O₂⁻ ⇒2K⁺O⁻²H⁺ + I₂⁰
Reaction 2: Cl₂⁰ + H₂⁰ ⇒ 2H⁺CI⁻
Next, we can see that iodine is being oxidized and oxygen reduced in reaction #1 and chlorine is being reduced and hydrogen oxidized in reaction #2 because the oxidized species increase the oxidation number whereas the reduced ones decrease it.
In such a way, the correct choice is C.
