Explanation :
Atomic number is defined as the number of protons or number of electrons.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and number of neutrons.
Number of neutrons = Mass number - Number of protons
Number of electrons = Number of protons - charge
Element Number of Number of Number of Atomic
symbol protons electrons neutrons mass

Potassium chlorate decomposes to form potassium chloride and oxygen.
Balancefd equation is as follows;
2KClO₃ --> 2KCl + 3O₂
stoichiometry of KClO₃ to O₂ is 2:3
At STP, 1 mol of any gas occupies a volume of 22.4 L.
Number of moles in 22.4 L is - 1 mol
Therefore in 11.2 L - 1/22.4 x 11.2 = 0.5 mol
When 3 mol of O₂ are formed - 2 mol of KClO₃ react
therefore when 0.5 mol of O₂ are formed - 2/3 x 0.5 = 0.33 mol of KClO₃ reacted
Therefore 0.33 mol of KClO₃ are required
the mass of KClO₃ required - 0.33 mol x 122.5 g/mol = 40.43 g
72.0726 is the percent for carbon
Earthquakes generate three types of seismic waves<span>: P (primary) </span>waves<span>, S (secondary) </span>waves<span> and surface </span>waves<span>, which arrive at </span>seismic<span> recording stations one after another. Both P and S </span>waves<span>penetrate the interior of the Earth while surface </span>waves<span> do not. Due to this, P and S </span>waves<span> are known as "body </span>waves<span>".

Answer:
a. True
Explanation:
The control objectives seek to support the fulfillment of the critical factors of business success, in order to finally support the achievement of the institutional objectives, on this the CITI is based
It is very important to clearly identify the relationships of the control objectives with other internal control elements such as:
· Critical success factors receive direct support from control objectives to support compliance.
· The control objectives are made up of control goals, which allow them to have a more detailed perspective of the control objectives and at the same time facilitate the evaluation of their compliance.
CITI CONCEPT:
It is the set of administration elements that a company establishes in a coordinated way so that the use of information technology resources effectively supports the institutional objectives of the company
