a. Spectator ions are the ones that are present but does not enter into the actual chemical  reaction.

b. Na⁺ and NO₃⁻ ions are spectator ions involved in this above mentioned reaction

<u>Explanation:</u>

  • In redox reactions, for example reaction of aqueous silver nitrate and aqueous sodium chloride, silver chloride settles down as a precipitate by the addition of Ag⁺ ion from AgNO₃ and Cl⁻ ions from NaCl .
  • The other 2 ions that is NO₃⁻ ion and Na⁺ ion in the reaction do not enter into the reaction and they are called as Spectator ions.

This can be expressed as the following equation,

AgNO₃(aq) + NaCl(aq) →AgCl(s) + NaNO₃

What mass of copper is produced when zinc is added to a solution containing 31.9g copper ii tetraoxosulphate vi
solmaris [256]

Answer:

12.7g of Cu

Explanation:

First let us generate a balanced equation for the reaction. This is illustrated below:

Zn + CuSO4 —> ZnSO4 + Cu

Molar Mass of Cu = 63.5g/mol

Molar Mass of CuSO4 = 63.5 + 32 + (16x4) = 63.5 + 32 + 64 = 159.5g/mol

From the equation,

159.5g of CuSO4 produced 63.5g of Cu.

Therefore, 31.9g of CuSO4 will produce = (31.9 x 63.5) / 159.5 = 12.7g of Cu

What is the working of NMR?
tiny-mole [99]

Answer:

NMR stands for Nuclear Magnetic Resonance, and NMR spectroscopy is the technology that makes use of the phenomena of NMR in the analysis of a material's molecular structure through measurement and observance of the nuclear spin interactions, in order to determine the biological, physical and chemical properties of the material

NMR works by the noting that some atoms in molecules placed in a strong magnetic field display the characteristics of small magnets. The application of a broad spectrum radio frequency to the molecules will cause the nuclei to resonate at particular frequencies. An NMR spectrum is formed from the measured nuclei resonant frequencies such that the graph peaks shows the correct frequencies in the sample and the peak height is directly related to the proportion or number of the nuclei which are resonating to a given frequency, such that the frequency values are indicative of the type of atoms and their distances apart from a given atom
