The second level has s and p orbitals, the s orbital holds two electrons and all three p orbitals also hold two each for a total of eight electrons in the second energy level.
The answer is ‘matter’ as every living object and everything around us is made up of matter.
Hope it helps :)
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%
In order to determine, Order of reaction, we have to add all the exponents written in the Chemical form, on the Reactant species.

The concentration of hydrogen ion of a sample of vinegar : 1.514 x 10⁻⁷
<h3>Further explanation
</h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
pH = - log [H⁺]
pH of a sample vinegar = 6.82
The concentration of hydrogen ion :
![\tt 6.82=-log[H^+]\\\\(H^+]=10^{-6.82}=1.514\times 10^{-7}](https://tex.z-dn.net/?f=%5Ctt%206.82%3D-log%5BH%5E%2B%5D%5C%5C%5C%5C%28H%5E%2B%5D%3D10%5E%7B-6.82%7D%3D1.514%5Ctimes%2010%5E%7B-7%7D)
