Answer:

Catalyst is referred to as the substance used in the reaction to speed up or to increase the efficiency of the reaction. the catalyst itself does not alter any change during the reaction. As catalyst itself is not the reactant or product thus it does not appear in a chemical reaction

Explanation:

Catalyst is referred to as the substance used in the reaction to speed up or to increase the efficiency of the reaction. the catalyst itself does not alter any change during the reaction. As catalyst itself is not the reactant or product thus it does not appear in a chemical reaction

In a chemical reaction, the catalyst is used to decrease the activation energy thus to provide or enhance the reaction mechanism to the reaction.

If you mix cu2+ with? a. nacl, b. nano2, c. h2o , arrange the solutions based on their absorption from highest frequency to lowe
erica [24]

The arrangement of the solutions based on their absorption from highest frequency to lowest frequency :

b.NaNO_{2} > c.H_{2} O > a.NaCl

<h3>What is absorption frequency?</h3>
  • The frequency of the molecular vibration that led to the absorption is the same as the absorption frequency of a basic IR absorption band.
  • In a way, an emission spectrum is the opposite of an absorption spectrum.
  • The discrepancies in the energy levels of each chemical element's orbitals correspond to absorption lines for each chemical element at various particular wavelengths.
  • Therefore, it is possible to identify the constituents in a gas or liquid using its absorption spectrum.
  • Absorption spectroscopy is most frequently used to measure infrared, atomic, visible, ultraviolet (UV), and x-ray waves.

Bond order of n2<br><br>bond order of N2 ​
snow_lady [41]

Answer:

The MO method for N2+ gives the bond order equal to 2.5. But first, we look at the diagram of molecular orbitals for N2 (the bond order for the nitrogen molecule is 3). the N2+ molecule). That is, the bond order for N2+ is 2.5.
