It will be a unitary system where all provinces, regions and subdivisions follow one order from the executive department. Majority of these are used by several countries where others are considering to have it changed to federalism. When there is no federalism, the sectors and pillars only act upon the dictation of the central government.

Answer:
21,760 or 22,000
Explanation:
Find out what is 4.5% of 16,000 which will get you to 720.
720 times 8 equals 5,760.
16,000 + 5,760 = 21,760
rounded to the nearest whole number is 22,000
The answer would be D
The equation has been shifted to the right 1 unit so you would plug in -2 for x
Answer:
Taking into account the reaction stoichiometry, the correct answer is option B): 9 grams of aluminum are necessary to produce 0.50 mol of hydrogen gas at 25°C and 1.0 atm.
Explanation:
The balanced reaccion is:
6 HCl + 2 Al → 2 AlCl₃ + 3 H₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
HCl: 6 moles
Al: 2 moles
AlCl₃: 2 moles
H₂: 3 moles
The atomic mass of aluminum is 27 g/mole. Then, by reaction stoichiometry, the following mass quantity of aluminum participates in the reaction:
Then you can apply the following rule of three: if by reaction stoichiometry 3 moles of H₂ are formed from 54 grams of Al, 0.50 moles of H₂ are formed from how much mass of Al?
mass of Al= 9 grams
In summary, the correct answer is option B): 9 grams of aluminum are necessary to produce 0.50 mol of hydrogen gas at 25°C and 1.0 atm
