If you determine the molar heat of neutralization for an acid is 49.1 kJ/mol and the accepted value is found to be 55.2 kJ/mol,
zhenek [66]

Answer: % Errror = 11.05%

Explanation:

Percentage error is the difference between the measured value and the theoretical value as expressed in percent.

That is;

% Error =

( Theoretical value -measured value) /(Theoretical value) × 100

Theoretical value =55.2kJ

Measured value = 49.1kJ

% Error = (55.2-49.1)/(55.2) ×100

%Error = 6.1/55.2 ×100

% Error = 0.1105 ×100

% Error = 11.05

Therefore the percentage error is 11.05%

lesya [120]
The answer is B. Unsaturated hydrocarbons will be hydrocarbons that have twofold or triple covalent securities between neighboring carbon particles. Those with no less than one carbon-to-carbon twofold bond are called alkenes and those with no less than one carbon-to-carbon triple bond are called alkynes.
