Why absolute value of enthalpy of system cannot be measured?
The absolute value of enthalpy cannot be measured because enthalpy is a state function, which means its value depends on the initial and final states rather than the absolute value. Only changes in enthalpy can be measured experimentally through processes like calorimetry.
What does the term "literature value" mean in the context of chemistry?
In chemistry, the term "literature value" refers to a known or accepted value for a specific measurement or property that is found in scientific literature. It serves as a reference point for comparison with experimental results obtained in research or laboratory work.
What is literature value in chemistry?
Literature value in chemistry refers to the accepted or established value of a physical or chemical property that can be found in scientific literature. It serves as a point of reference for comparing and validating experimental results obtained in the laboratory. Comparing experimental results to literature values helps scientists assess the accuracy and reliability of their measurements.
How can one find the value of q in chemistry?
To find the value of q in chemistry, one can use the formula q m c T, where q represents the heat energy, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature. By plugging in the known values for mass, specific heat capacity, and temperature change, one can calculate the value of q.
What is the pKa value of an imine functional group and how does it affect its reactivity in organic chemistry reactions?
The pKa value of an imine functional group is typically around 9-10. A lower pKa value indicates that the imine is more acidic and therefore more reactive in organic chemistry reactions. This increased reactivity allows imines to participate in various reactions such as nucleophilic addition and condensation reactions.
Is Chemistry relative science or absolute science?
absolute
Distance a number is from zero?
That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.
What number has the absolute value as -4?
no number; absolute value is always positive. The absolute value of a negative number is positive. For example absolute value of -4 is +4
What is the absolute value of -19?
The absolute value of 19 is 19. If x is positive , absolute x equals x.
Information about absolute value?
Absolute value is the distance of a number from zero on a number line.
What is the integer's absolute value?
An interger's absolute value is how far away it is from 0, so an interger's absolute value will always be positive. The absolute value of -83 is 83. The absolute value of 178 is 178. etc.
What is absolute value and why is it useful?
The absolute value is when even if a negative number when put in absolute value signs is positive such as.. l-23 l the absolute value is 23. l..l are absolute value signs
What is the absolute value of 14?
Absolute value of 14 is 14.
How does the absolute value of -7 compare to the absolute value of 7?
They are the same. the absolute value is always positive
What is the absolute value of-607?
The absolute value of something is its difference from 0. Absolute value of -607=607
What is an absolute function?
The absolute value function returns the absolute value of a number.
Is the absolute value of negative 7 less than the absolute value of 7?
the absolute value of negative 7 is 7 and the absolute value of 7 is also seven so they are equal. Therefore, the absolute value of negative 7 is not less than the absolute value of 7. Remember that absolute value means the positive of a number
