The molecule has two chiral carbons
Explanation:
i hope its the right answer
Answer:
Following are the solution to this question:
Explanation:


![[H_3O^{+}] =[HCl] \\\\\to [H_3O^{+}] =0.5064 \ m \\\\\to PH =-\log [H_3O^{+}] \\\\](https://tex.z-dn.net/?f=%5BH_3O%5E%7B%2B%7D%5D%20%3D%5BHCl%5D%20%5C%5C%5C%5C%5Cto%20%5BH_3O%5E%7B%2B%7D%5D%20%3D0.5064%20%5C%20m%20%5C%5C%5C%5C%5Cto%20PH%20%3D-%5Clog%20%5BH_3O%5E%7B%2B%7D%5D%20%5C%5C%5C%5C)

B is correct
salt lowers the freezing point of water (colligative property) by lowering the interaction and intermolecular forces between water molecules
2Fe+ 6HBr ---> 2FeBr3 +3H2
Fe is a reducing agent is what that is true in equation above This is because it oxidation state move from zero to positive three.Reducing agent is an element or compound that loses or donate an electron to another chemical species in a redox chemical reaction. Fe is oxidized since it loses electron in the redox reaction
