Substances X and Y can act as oxidizing agents. Substance X is blue and substance Y is red. They can form the ions X- and Y-, respectively - both of which are colorless. When a blue solution of X is mixed with a colorless solution containing Y- ions, the color changes from blue to red. What are the products of the reaction

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

so what is the problem with your lab report and whats the subject of the lab report? i will you

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
