A similarity between the separation of powers the system of checks and balances and federalism is?
A similarity between the separation of powers, the system of checks and balances, and federalism is that they all are meant to keep the federal government from becoming too powerful and tyrannical.
Answer:
Federalism and Separation of Powers policies seek for decentralised the power and avoid tyranny.
Explanation:
Separation of Powers, according to Montesquieu, is a policy that allow the country to have democracy, because this separation is constituted by three main autonomous powers: judicial, executive and legislative. Each institution can judge others, so this way whole nation power is not concentrated in one point.
In this way, Federalism is alike, because this policy is about having a central government (Federal), and regional governments (States) in a whole political system. So, each regional government has their own rules and freedom to their jurisdiction.

If enough heat was REMOVED from B, it would change into A.
An exothermic reaction is a reaction that releases energy, this energy is usually in the form of heat. An endothermic reaction is a reaction that absorbs energy to take place.
To bring molecules together requires the release of energy, that is, an exothermic reaction.
Thus, if heat were removed from B, it would turn into A, with molecules closer together, in the solid state.

B) the number of products is less that the number of reactants
C) the number of products is the same as the number of reactants
D) the number of products may be greater or less than the number of reactants
Answers
Answer: The correct answer is Option B.
Explanation:
Synthesis reaction is defined as the reaction in which two or more substances combine in their elemental state to form a single compound.
The general equation representing this reaction follows:
As, number of reactants in this type of reaction will always be more bacuse a single product is forming in this reaction.
Thus, the correct answer is Option B.
2. Calculate the moles of O in the sample.
Answers
Answer:
The answers are
C = 0.0895 moles
1. 0.02975 moles of N
2. 0.0299 moles O
Explanation:
Mass of sample = 2.18 g
Combustion yields 3.94 g of CO₂ and 1.89 g of H₂O
1.23 g of sample contains 0.235 g of N
3.94 g of CO₂ which contains one mole of C and two moles of O
Molar mass of CO₂ = 44 mass fraction of C = 12/44 = 0.273, Therefore mass of carbon in 2.18 g = 0.273×3.94 = 1.075 g
number of moles of C in sample = mass/(molar mass) = 1.075 g/(12.01 g/mol) = 0.0895 moles of C
(1) Mass of nitrogen, in 1.23 g of sample = 0.235
therefore mass in 2.18 g =0.235×2.18/1.23 = 0.4165 g
= 0.02975 moles of N
(2) To find the number of moles of oxygen in the sample we note that total mass of sample = 2.18 g containing only nitrogen, hydrogen, oxygen and carbon
Mass of hydrogen can be fround from 2/18×1.89 = 0.21 g
Mass of oxygen therefore = 2.18 -(0.21+0.4165+1.075) = 0.4785
number of moles = 0.475/16 = 0.0299 moles
