the energy required to transform a given quantity of a substance from a liquid into a vapor or gas at a given pressure so the enthalpy of them also different. simply can we say heat is released by the substance also differ such as heat capacity of water and HCL. In addition , pressure and volume of them not same at same temperature. thank you

The standard heat of vaporization values differ between H2O and HCl because of differences in molecular structure and intermolecular forces. H2O has hydrogen bonding, which results in stronger intermolecular forces and a higher heat of vaporization compared to HCl, which has weaker dipole-dipole interactions. Additionally, the molecular weight and specific properties of each compound also contribute to the difference in their heat of vaporization values.

The accepted standard state values for temperature is 298 K (25°C) and pressure is 1 bar (100 kPa).
Why is experimenral value different from literature value in chimestry?
Experimental values may differ from literature values in chemistry due to errors in measurement techniques, equipment calibration, sample purity, or human error in performing experiments. Additionally, variation in experimental conditions, such as temperature, pressure, or reaction time, can also contribute to discrepancies between experimental and literature values.
How should the values found using the zinc electrode as a standard compare with those based on the standard hydrogen electrode?
When using the zinc electrode as a standard, the values obtained will be relative to the standard hydrogen electrode (SHE). The potential difference between the two electrodes at a given condition can be used to calculate the standard electrode potential of the zinc electrode. This potential difference is due to the different standard hydrogen electrode potential (0 V) and standard zinc electrode potential (+0.76 V).
Where you could find the standard Rf values for fatty acids and poly unsaturated fatty acids?
You can typically find standard Rf values for fatty acids and polyunsaturated fatty acids in scientific literature, such as research papers, textbooks on chromatography, or chemical databases like ChemSpider or PubChem. These values may vary depending on the specific method and conditions used for their determination.
In the ninhydrin test why do absorbance values for glycine and tyrosine differ?
The absorbance values for glycine and tyrosine differ in the ninhydrin test because tyrosine contains an aromatic ring that reacts with ninhydrin to form a colored product, while glycine lacks this structure. The presence of the aromatic ring in tyrosine leads to a more intense color formation, resulting in a higher absorbance value compared to glycine.

How do you find the standard deviation?
The standard deviation (?, pronounced sigma) of a set of values is a measure of how much the set of values deviates from the average of the values. To calculate ? of a complete set of values (as opposed to a sampling),...Calculate the average of the set (the sum of the values divided by the quantity of the values).Calculate the difference between each value and the average calculated in step 1, then square the difference.Calculate the average of all the squares calculated in step 2.The standard deviation is the square root of the average calculated in step 3.

What percentage of data values of a normal distribution will fall within one standard deviation below the mean?
34.1% of the data values fall between (mean-1sd) and the mean.
How do you compute probabilities of a standard normal random variable?
You need to determine the area under the curve between the values in question. This is easy to do because there are tables that give the area values.

Carbon resistors are not available in market of each number of resistance why?
carbon resistors of standard values are manufactured because other values can be obtained by series and parallel combination of standard values. Moreover even standard values do not offer exact Resistance's will have tolerance
