meriva

Answer:

Melting and Boiling Point Determination

The physical properties of a substance can be used to establish its purity. These properties include the melting point and boiling point. Different substances tend to have different melting and boiling points, and any pure substance will have a specific melting and boiling point.

SO2Cl2 decomposes by first order kinetics and k=2,81x106-3 min-1 at a given temperature. The initial concentration of SO2Cl2=0.0
solmaris [256]

Answer:

246.67 min

Explanation:

Half life is the time at which the concentration of the reactant reduced to half.

Half life expression for first order kinetic is:

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

Given that;- k = 2.81\times 10^{-3}\ min^{-1} (Values corrected from source)

Thus,

t_{1/2}=\frac{\ln2}{2.81\times 10^{-3}\ min^{-1}}=\frac{\ln2}{2.81\times 10^{-3}}\ min

t_{1/2}==355.87188\ln \left(2\right)\ min=246.67\ min

<u>246.67 min is the half-life of the reaction.</u>

What is the reading on your balance and that of your partner?what do these values represent?
never [62]
These values may represent the amount of pulling force that  we exert on each other or in other words exert forces on both parties.


The answer may differ as well but keep in mind the values should be equal.

Note:

The answer is not about helping each other or the "spring balance". We are not talking about the literal moral values instead we are talking about Chemistry and Science.
