Answer:
The thermodynamic parameter which is of significance in this case is the 'Reduction Potential' for molecular bromine which is ~ +1.1 v vs N.H.E. In other words, it is a strong oxidizing agent. The bromine will oxidize sulfur compounds in which the valence of sulfur is lower than six to sulfate.
There are many possible reactions. Here is one possible example:
Na2 S2O3 + 4Br2 + 5 H2O = 2NaHSO4 + 8 HBr
Answer : The given statement is, false.
Explanation :
Ionic product of water : It is defined as the product of the concentration of hydrogen ion and the concentration of hydroxide ion.
The mathematical expression will be,
![[H^+][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
When the concentration of hydrogen ion and hydroxide ion are equal then the solution is neutral and the value will be,
. And the pH of the solution is, 7.
When the concentration of hydrogen ion is greater than
then the solution is acidic in nature. And the pH of the solution is, less than 7.
When the concentration of hydrogen ion is less than
then the solution is basic in nature. And the pH of the solution is, greater than 7.
Hence, the given statement is false.
Proteins are made of carbon, hydrogen,oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon,hydrogen, oxygen, nitrogen, and phosphorus(CHON P). The body also needs trace amounts of other elements such as calcium,potassium, and sulfur for proper functioning of muscles, nerves, etc.
Answer:
0.0125 mol.
Explanation:
<em>Molarity of a solution is the no. of moles of a solute per 1.0 L of the solution.</em>
<em></em>
M of HCl = 0.5 mol/L.
V = 25.0 mL = 0.025 L.
<em>∴ no. of moles of HCl present in the flask at this time = MV</em> = (0.5 mol/L)(0.025 L) = <em>0.0125 mol.</em>
