Answer:
* 
* ![[I_2]=0.011M](https://tex.z-dn.net/?f=%5BI_2%5D%3D0.011M)
Explanation:
Hello,
In this case, considering the reaction:
Which is first-order with respect to I₂, we can compute the half-life by:
Moreover, since the integrated rate law is:
![[I_2]=[I_2]_0exp(-kt)](https://tex.z-dn.net/?f=%5BI_2%5D%3D%5BI_2%5D_0exp%28-kt%29)
We can compute the concentration of iodine once 5.37 s have passed:
![[I_2]=0.048Mexp(-0.271s^{-1}*5.37s)\\\\](https://tex.z-dn.net/?f=%5BI_2%5D%3D0.048Mexp%28-0.271s%5E%7B-1%7D%2A5.37s%29%5C%5C%5C%5C)
Best regards.
Molarity of solution is expressed as,
Molarity =
Molecular weight of KCl = 74.55 g/mol
For preparing 1 mol of KCl solution (1 liter), 74.44 g KCl must be dissolved in 1 liter of water.
Following glasswares are required for preparing the solution.
1) Watch Glass (for weight the KCl)
2) Beaker (for preparing the solution)
3) Stirrer (For dissolving KCl in water)
4) Standard measuring flask (To ensure final volume of solution is 1 liter)
The correct answer is:
neutrality
on the pH scale 7 is neutral above 7 is basic and below 7 is acidic.
Explanation:
The pH is an example of how acidic/basic water is. The scale goes from 0 - 14, with 7 being neutral, pH of less than 7 designates acidity, whereas a pH of greater than 7 intimates a base. pH is really a pattern of the relative amount of free hydrogen and hydroxyl ions in the water.pH is a measure of how acidic/basic water is.
It is neutral because, at this pH, the molar concentrations of Hydroxide and Hydronium are same, therefore the substance is not a base nor an acid.
Answer:
Elements in the same group of the periodic table have the same number of valence electrons. These are the electrons in their outer energy level that can be involved in chemical reactions. ... All the elements in group 1 have just one valence electron. This makes them very reactive.
Explanation:
Answer:
Sodium and chloride ions separate when salts are dissolved in water. The dissolved sodium and chloride ions, in high concentrations, can displace other mineral nutrients in the soil. Plants then absorb the chlorine and sodium instead of needed plant nutrients such as potassium and phosphorus, leading to deficiencies.
