The yeast acted as a catalyst. Explain the purpose of a catalyst in a reaction
Anna71 [15]

Answer:

The catalyst speeds up the chemical reaction.

Explanation:

The process in which chemical reaction rate increases by addition of substance is termed as a catalyst. The chemical reaction happens faster when a catalyst is present because it gives an alternative reaction pathway with lower activation energy.

The catalyst usually forms a temporary intermediate that helps in regenerating the original catalyst in the cyclic process. Yeast when added in a mixture work as a catalyst and helps with chemical reaction.

How many nonbonding electron pairs are there in the lewis structure of the peroxide ion, o22−?
Tom [10]
There is 6 non - bonding pairs.
Let me show you one easy method to do this.
o22-, oxygen valence electron = 6 here we have two so total 12, and -2 that means we add electrons so it’s all equal to 14 right.
whenever need to find lone pair, subtract the number you get with the lowest multiple of 8.
here we total 14 valence electron right so lowest multiple of 8 would be 8.
so 14 - 8 = 6 and that is our answer.
Let me know if you have Problem with chemistry.

A spectrophotometer measures the transmittance or the absorbance, or both, of a particular wavelength of light after it has pass
Cerrena [4.2K]

Answer:Answer: The step that is NOT necessary to complete before a cuvette is placed into the spectrophotometer is option B (Write, in ink, either sample or blank on the side of the cuvette to keep track of them)

Explanation: spectrophotometer is an instrument used to measure the light intensity absorbed after being passed through a solution. Before the absorbance of the sample solution, a solvent solution called blank is used for the calibration of the machine and this blank solvent is placed in a cuvette. The procedure usually comes first before the main sample is processed. Therefore there is no need to

Write, in ink, either sample or blank on the side of the cuvette to keep track of them. This is so since sample and blank is not absorbed at the same time by the machine.
