The balanced net ionic equation should be written and oxidation numbers of all species involving in the reaction should be assigned and oxidizing and reducing agents should be identified. Concept introduction: Net ionic equation: Only the species, which are involving in product formation in present in the equation, is known as net ionic equation. The net ionic equation is derived from cancelling of spectator ions in ionic equation. Oxidation Numbers: Oxidation Numbers is number, which gives the information about the number of electrons lost or gained by atom or element in the formation of compound by redox reaction . In generally an atom are ion gains an electron from redox reaction is known as reduction and the atom are ion loosed its electron in redox reaction is known as oxidation. Oxidation increases the positive charge on atom or ion and reduction increases the negative charge on atom or ion. The total oxidation numbers of molecules are zero, noble gases and elemental form of all atoms are having 0 oxidation number. The common oxidation number for Hydrogen is +1, Oxygen is -2, halides -1, earth metals are +1 and alkaline earth metals are +2.

Interpretation Introduction

Interpretation:

The balanced net ionic equation should be written and oxidation numbers of all species involving in the reaction should be assigned and oxidizing and reducing agents should be identified.

Concept introduction:

Net ionic equation:

Only the species, which are involving in product formation in present in the equation, is known as net ionic equation.

The net ionic equation is derived from cancelling of spectator ions in ionic equation.

Oxidation Numbers:

Oxidation Numbers is number, which gives the information about the number of electrons lost or gained by atom or element in the formation of compound by redox reaction.

In generally an atom are ion gains an electron from redox reaction is known as reduction and the atom are ion loosed its electron in redox reaction is known as oxidation.

Oxidation increases the positive charge on atom or ion and reduction increases the negative charge on atom or ion.

The total oxidation numbers of molecules are zero, noble gases and elemental form of all atoms are having 0 oxidation number.

The common oxidation number for Hydrogen is +1, Oxygen is -2, halides -1, earth metals are +1 and alkaline earth metals are +2.

2. Make an ice cube at 1 bar pressure by freezing an amount of liquid water that is 2 cm x 2 cm x 2 cm in volume. The density of liquid water at 0 °C is 1.000 g cm³ and the density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason your water pipes burst if they freeze and why you shouldn't forget to take your bottle of pop out of the freezer if you put it in there to try and cool it down faster. A. What is the work of expansion upon freezing? B. Is work done on the system or by the system?

I have a excitation/emission spectra of a quinine standard solution here, and I'm having trouble interpreting it. the red line is emission the blue line is excitation. i'm having trouble interpreting properly. just want to know if there is any evidence of raman or rayleigh peaks in the spectra.
